China has always tried to maintain multilateralism and advocated working together to deal with global climate change through multilateral mechanisms. Although China’s announcement to peak its carbon emissions by 2030 comes as no surprise, its commitment to carbon neutrality does. As the period between its carbon peaking and carbon neutrality is far shorter than that in the developed countries, China’s economic and energy structures need to be adjusted toward the low-carbon and carbon-free end with unprecedented efforts. To that end, China should define the responsibilities of local authorities and industrial entities to promote the orderly accomplishment of carbon peaking in all regions and industries. To supply the huge investments needed to achieve the goals of carbon peaking and carbon neutrality, China has an urgent need to accelerate the development of green finance and a national carbon emissions trading market, guide the rational allocation of resources, and channel resources to eco-friendly projects for green and low-carbon development. At the same time, China and the international community should strengthen dialogue and coordination, promote international cooperation on the way to carbon neutrality, formulate widely acceptable policy guidelines as soon as possible, and avoid unilateral measures that may cause conflicts.

Whereas the implementation of the Tourism Protocol of the Alpine Convention seems far from its completion, the Alpine Convention fourth report on the state of the Alps "Sustainable Tourism in the Alps" is under preparation and it is expected by the end of 2012. One of the main critical challenges that Alpine tourism needs to face in the quest for sustainability is climate change. In recent years several research and cooperation projects focusing on the Alpine region have been dealing with the issue of climate change. In particular the Alpine Space Programme, starting with ClimChAlp (2006-2008), focused on the issue of adaptation to climate change in the following call (2008-2011) through several projects: CLISP, ClimAlpTour, Manfred, AdaptAlp, AlpWaterScarce, ParaMount, PermaNet, SILMAS, AlpFFIRS. These projects led to a capitalization project named C3Alps that recently started. At the same time, the Alpstar project, which also started recently, will focus on climate change mitigation and on making the Alps a carbon neutral environment. The Euro-Mediterranean Centre for Climate Change (CMCC) contributed to several of these Alpine Space projects (ClimChAlp, AdaptAlp, ClimAlpTour and C3Alps). Other non Alpine Space projects have also contributed to this research and cooperation issue, such as CC.ALPS (by CIPRA), KLIWA (by various German and Bavarian institutions), Histalp (Austrian weather service), etc. However, ClimAlpTour is the only project that explicitly focused on tourism. This paper builds on these projects’ findings, especially for what concerns the implications for the tourism sector, and on the existing relevant literature.

Externalities influencing countries, such as wars tend to disrupt the regular economic and social processes. This paper analysis how a military conflict impacts the efforts of world acters in climate change and carbon neutrality. It focuses on armed conflict between Russian Federation and Ukraine, research the most recent available data and compare the emissions in given periods in order to provide and estimated impact of such events on climate efforts of countries directly and indirectly involved in conflict. Assumption, that crises directly lead to neglecting the climate goals and therefore an increase in GHG emissions is tested. Paper also analyzes the overall impact of war on GHG emissions, providing a overview of its severity. The results indicate that emissions on territory of countries directly involved in conflict tend to increase significantly, while change in emissions of external actors are insignificant. Results that would confirm or disprove the assumption of increased GHG emissions during crises are inconclusive and indicate a high subjectivity. [ABSTRACT FROM AUTHOR]

LAND degradation ,CARBON offsetting ,PARIS Agreement (2016) ,CLIMATE change ,ECONOMIC models - Abstract
Land is being degraded rapidly worldwide. United Nations Convention to Combat Desertification in 2015 has invited countries to formulate voluntary targets to achieve Land Degradation Neutrality (LDN). Under the Paris Agreement, a legally binding international treaty adopted in 2015, the world is transitioning toward Carbon Neutrality (CN) with more mitigation actions. This paper intended to review the concepts of land degradation, LDN along with CN emphasizing the degradation types, approaches, models available to analyze, synergies, economic aspects and challenges. The review explores approaches and models available for achieving LDN and CN which are both synergistic, economically efficient and could overcome the common challenges. Land degradation has to focus beyond the traditional definitions to incorporate more persistent and the difficult to restore degradation causes. Such complex land degradation requires specialized LDN approaches. The level of degradation and restoration progress could be analyzed using a variety of modeling approaches including economic models. Approaches for LDN and CN can bring significant synergies for each other. The approach proposed by the present study will provide a logical flow for decision-making while minimizing time and effort and avoiding a piecemeal approach. The approach therefore maximizes the output in relation to the inputs thus enhancing sustainability. [ABSTRACT FROM AUTHOR]

How have 30 years of development in energy and climate policies influenced long-term trends in China and what does this imply for future climate policies? To answer the question, this article examines three decades of energy and climate policies in China. By providing an overarching review, it contributes new and updated research on drivers behind long-term climate policies and whether China's long-term emissions trend can be broken by placing greater emphasis on innovation, technology and low-carbon development. Importantly, it analyses the most recent policy developments in China, such as the likely effects of China's recent 2060 carbon neutrality goal. We conclude that after the Paris Agreement, the biggest policy change has been technological innovation in the power and transport sector. China has prioritized measures, laws and policies for developing renewable energy, especially solar and wind. China has also embraced the 'green growth' approach for responding to the challenges of climate change. These efforts have yielded results, and China has emerged as a world leader in renewable energy. However, there is still a long way to go. The upcoming 14th five-year plan will be critical for accelerating the energy transition, including setting a cap on coal in the national energy-transition strategy.

The iron and steel industry is the largest carbon emitter in China's manufacturing sector and one of the most important fields in the country's response to climate change. This paper aims to explain the current situation, technological pathways, and future direction of green and low-carbon development of the iron and steel industry. According to the carbon emissions of the iron and steel industry, this paper analyzes the relationship between steelmaking technologies and carbon emissions, as well as the transformation trend of the world's iron and steel industry, finding that China's iron and steel industry faces both opportunities and challenges. Steel scrap recycling and electric furnace steelmaking technologies, re-electrification, hydrogen metallurgy, resource recycling and by-products, and carbon capture and utilization (CCU) are the main technologies tailored to the transformation pathways, and the optimization of energy consumption structure is an important direction for future development. Therefore, this paper believes that clean energy, as a guarantee for carbon mitigation, will play an increasingly important role in the process towards achieving carbon peaking and carbon neutrality goals (the "dual carbon" goals), in addition to the transformation of metallurgical technologies.

- Abstract
Carbon neutrality is an important policy in the current global response to climate change and has been widely recognized by various industries. In the process of promoting carbon neutrality, new energy plays a pivotal role. In this study, the definition and connotation of new energy and its role and specific operation in the energy transition of carbon neutrality are firstly explained. Promoting new energy development requires significant green and low-carbon investments. Taking China as an example, this paper analyzes the opportunities brought by the carbon neutral process to the field of green finance and analyzes the main features and development trends of green finance in China at present. Then this paper proposes policy recommendations to strengthen the development of green finance in China in terms of improving the green financial policy system, enhancing the supply capacity of green financial services, and optimizing the supporting environment for green financial development. Finally, this paper analyzes the measures and experiences of the United States in promoting low-carbon development and proposes countermeasures for China's low-carbon development on the basis of the five major relationships that need attention in China's carbon-neutral process. That is, strengthen the top-level design and improve the regulatory policy system; optimize the energy structure and increase the proportion of clean energy; optimize the industrial structure and reduce energy consumption in key industries; build a complete low-carbon technology system and promote low-carbon technology research and development and demonstration applications, and encourage local conditions to explore low-carbon development paths. The development of green finance can contribute to the advancement of new energy technologies, thus contributing to the achievement of carbon neutrality goals. [ABSTRACT FROM AUTHOR]

COVID-19 brought new marketing disruptions in the tourism sector amid global traction and action towards carbon neutrality, following the Paris Agreement of 2015 and the Glasgow Pact of achieving NetZero emissions by 2050. Drawing from the Ad Net Zero Guide 10-Point Plan for businesses to infuse climate action (SDG 13) into their operations, this study utilizes a qualitative approach through annual and other company reports, interviews, observations, and Question Pros from Sun City hotels to examine the progress of the hospitality industry. The results reveal that the four hotels, Cabanas Hotel, Sun City Hotel, The Palace Hotel, and Cascades Hotel have green initiatives that improve water, waste, and energy efficiency. There is a slow pace to enforce saving the environment at a faster pace in the resort. The findings reveal that marketing communication strategies employed by Sun City Resort in exhibiting green initiatives were moderately successful. The findings reveal that the four hotels in Sun City generally harnessed the 10-Point Plan, although this may not be explicitly credited to the 2020 Ad Net Zero Initiative. The paper recommends that the entities under consideration keep improving their commitment to the Climate Action SDG and market on-the-ground initiatives widely for peer learning and to save the environment, lives, and livelihoods. However, more actions and policies need to be in place to reduce carbon emissions such as reuse, recycling, and reduction and applying sustainable marketing. [ABSTRACT FROM AUTHOR]

Under the increasingly severe climate crisis, it is of great significance to carry out research on carbon budget calculation and multi-scenario prediction under the "double carbon" target for realizing regional low-carbon and high-quality development. Taking the Yellow River Basin (YRB) of China as the research area, this paper firstly calculates the carbon budget of the YRB from 2000 to 2020 and analyzes its spatiotemporal change. Then, we simulated carbon emissions, carbon sequestration, and net carbon budget during 2030-2100 under the SSP1-5 scenario. Finally, the regulation strategies of carbon balance of the YRB were proposed from four aspects: strengthening ecological governance, improving land use mode, optimizing industrial structure and advocating low-carbon life. Our results showed: (1) The overall carbon sequestration and carbon emission show a trend of fluctuating increase during 2000 to 2020, but the increase rate of carbon emission is far greater than carbon storage. The net carbon emission during 2000-2020 is negative, which is manifested as a carbon sink area. (2) The order of carbon sequestration of the provinces in the YRB during 2030-2100 is the same under the SSP1-5 scenario, and the descending order is the following: Inner Mongolia, Qinghai, Shaanxi, Gansu, Shanxi, Henan, Ningxia, and Shandong. (3) The STIRPAT model can be used to predict the carbon emissions of the YRB in the future with high precision. (4) In terms of net carbon emissions, under the SSP1-5 scenario, the YRB will be a carbon sink area from 2030 to 2080, and a carbon source area from 2080 to 2100. (5) Different provinces have different paths to low-carbon development, Inner Mongolia and Qinghai maintain a good low-carbon development path under SSP1, SSP2 and SSP4 scenarios, Ningxia and Shandong maintain a good low-carbon development path under SSP1 and SSP2 scenarios, Shanxi maintains a good low-carbon development path under SSP1 and SSP3 scenarios, and Gansu, Shaanxi and Henan maintain a good low-carbon development path under the SSP3 scenario.

This paper aims to explore how the COVID-19 pandemic influenced the implementation of the European Green Deal and to which extent have the European Union's green growth and sustainable development goals been incorporated into its COVID-19 Recovery Strategy. The European Union's Green Deal, a 'generation defining' growth strategy, which lays down the strategic pathway of the European Union's economic development for the upcoming two decades, has been faced with a major challenge shortly after its adoption in December 2019. However, despite the COVID-19 pandemic, which has continuously been putting all European Union member states to a harsh challenge during the past year, climate change and the green transition have been at the top of the political agenda in the European Union and have managed to occupy the attention of the mainstream politics and European Union citizens. Furthermore, the unprecedented levels of public financing which have been mobilised due to the pandemic have provided an opportunity for speeding up the green transition, without which the achievement of the Green Deal's main aims and the fulfilment of the European Union's obligations under the Paris Agreement would likely be put in question. In order to analyse how the has the COVID-19 pandemic influenced the implementation of the Green Deal, the paper first examines how the member states and the European Union institutions initially reacted to the idea of pursuing the implementation of the Green Deal simultaneously with economic recovery. This is accomplished through an analysis of statements given by the European Union and member state officials and the adopted measures and legislative proposals. The paper then focuses on publicly available data on legislative delays in regard to the implementation of the Green Deal which took place due to the pandemic and concludes that no significant postponements occurred. It subsequently turns to examine which measures have been adopted at the European Union level that link the economic recovery and the green transition. In this regard, special attention is paid to the Recovery and Resilience Facility and its measures aimed at ensuring that member states pursue climate change and environmental objectives in their recovery plans. Given the size of the public investments which will take place in the following years, the paper emphasises the importance of stringent environmental standards in order to ensure that they contribute to the green transition and avoid a fossil fuel lock-in.

Featured Application: The Intergovernmental Panel on Climate Change (IPCC)'s Sixth Assessment Report (AR6) recognizes the physico-chemical process known as carbonation. The present paper utilizes a way of calculating carbon dioxide uptake quickly and easily following the simplified methodology known as Tier 1 applied to the largest cement consumer in South America. The worldwide cement industry plays an important role in addressing the climate change challenge. Brazil's cement industry currently has 91 cement plants with an installed production capacity of 94 million tons per year and has started to calculate the net CO
2 emissions to achieve a carbon-neutral cement sector by 2050. Accordingly, the carbon dioxide uptake due to mortar and concrete carbonation is subtracted from the carbon dioxide emitted by the chemical reaction for the calcination of lime, i.e., the calcination process performed during clinker production. Now-adays, the Intergovernmental Panel on Climate Change (IPCC) Guidelines for National Greenhouse Gas (GHG) Inventories to report the GHG emissions do not include any calculation procedure to consider the mortar and concrete carbonation. However, the Intergovernmental Panel on Climate Change (IPCC)'s Sixth Assessment Report (AR6) recognizes the physico-chemical process known as carbonation. Brazilian net carbon dioxide emissions of cements produced from 1990 to 2019 are estimated considering the carbon dioxide uptake during the service-life and end-of-life and secondary usage stages (Tier 1). This is a fundamental scientific and technological novelty that changes the current approach to estimate the carbon dioxide emissions due to the Portland cement clinker production. Even considering the relative novelty of this approach, it should be promoted in the future and included in the national inventory report (NIR). The carbon dioxide uptake by mortar and concrete carbonation for 30 years is about 140 million tons. Within this thirty-year period about 483 million tons have been released due to the calcination process. [ABSTRACT FROM AUTHOR]- Published

The Chinese government's use of fiscal policy, which includes fiscal income and spending, is crucial in its fight against environmental pollution and climate change. Innovation‐driven has arisen as a new alternative to reconcile economic success with environmental conservation in light of tighter resource restrictions and the suggestion of the Chinese High‐quality Development policy. The paper uses an econometric model to examine the connection between institutional resource consumption efficiency and carbon neutrality, using a data set consisting of Chinese inter‐provincial panel data from 2007 to 2020 as a research sample; fiscal decentralization is also discussed as a potential moderating factor. Collaborative innovation positively boosts ecological efficiency and produces geographical spillovers, and the findings suggest so long as the economic distance is considered. When it comes to increasing ecological efficiency, collaborative innovation plays a more important role than financial decentralization alone. Among these is the improvement of carbon neutrality, which is best achieved via the joint promotion of ecological efficiency and industrial organizations. By reducing the intensity of the positive effect of innovative cooperation on ecological efficiency, the moderating effect suggests that fiscal decentralization is a critical factor in this relationship. Promoting China's ecological efficiency necessitates a fair distribution of local budgetary spending. China should also actively encourage the degree of synergy between institutional resource consumption efficiency and associated institutions to improve eco‐efficiency. [ABSTRACT FROM AUTHOR]

Semiconductor and display industries in the Republic of Korea make up the global electronics market with some of the greatest potential for growth due to accelerated digital transformation. Greenhouse gases (GHGs) present in the Earth's atmosphere could trap heat and contribute to the greenhouse effect, leading to global warming and climate change, and it is important to note that while GHGs are naturally present in the atmosphere and play a crucial role in regulating the Earth's temperature, human activities have significantly increased their concentration, leading to accelerated global warming and climate change. Volatile fluorinated compounds (FCs), including perfluorocompounds (PFCs), hydrofluorocompounds (HFCs), NF
3 , and SF6 , are potent long-standing greenhouse gases that are used and emitted by electronics during the manufacturing and display stages of semiconductors. In accordance with global climate change, GHG reduction has developed as a demand of the times, and the electronics industry has also made efforts to reduce GHG emissions in response. Until now, process emissions from the use of fluorinated greenhouse gases (F-GHGs) in various industries have been calculated according to the '06 IPCC G/L, and emission factors of '06 IPCC G/L have also been applied. However, the reduction and emission factors proposed in the IPCC G/L are values that do not reflect the latest and advanced reduction technologies in South Korean electronics, and national GHG emissions are overestimated. In this paper, by preparing accurate measurement methods for destruction removal efficiency (DRE), the use rate of gas (Ui ), and b-product emission factors (Bby-product, i ), which are characteristic parameters for estimating GHG Tier 3a emissions, we aim to increase the accuracy of GHG emissions by advancing emission factors that are unique to the semiconductor and display industries within the Republic of Korea.

- Abstract
Interest in sustainability has increased significantly in the wine sector in the past few years, driven by customer interest, as well as the impact of global warming-intensified weather extremes on wine growers. For a sustainable future the wine industry must design its entire value chain in such ways that it conserves and regenerates the natural environment and at the same time promotes human rights, inclusion and equality. The current paper identified five key challenges which have to be overcome in order to reach this goal: (1) climate change impact and adaptation strategies, (2) the reduction of GHG emissions and creation of carbon sinks, (3) vineyard inputs, (4) packaging and (5) social and economic sustainability. For each of these five challenges research gaps and possible solutions are presented which enable a holistic improvement of the sustainability of the whole wine value chain from the vineyard to the consumers. Examples for this are strategies to reduce the use of pesticides in the vineyard as well as carbon insetting options in the vineyard. Additionally, it is of utmost importance that every educational institution integrates facts and vision into their teaching programs in a holistic manner. Together, these approaches form the basis for a realistic sustainability vision for the global wine industry. [ABSTRACT FROM AUTHOR]

The paper discusses existing trends and prospects for decarbonization in the Commonwealth of Independent States (the CIS), an international organization that regroups Armenia, Azerbaijan, Belarus, Kazakhstan, Kyrgyzstan, Moldova, Russia, Tajikistan, Turkmenistan, and Uzbekistan. The CIS occupies a significant share of Eurasia, representing a large share of global energy consumption and production with a corresponding carbon footprint. These countries and their decarbonization prospects are rarely discussed in the English-language scientific literature. This paper fills in this gap by offering a comprehensive analysis based on statistical data, policy documents, and scenario-based future projections. The results underline that revisiting Nationally Determined Contributions, increasing energy efficiency, and decoupling GDP growth from greenhouse gas emissions are essential to the implementation of the Paris Agreement. The future energy mix should include larger shares of renewable energy, hydrogen, fossil fuels (highly efficient with carbon capture), and nuclear energy to achieve energy security and decarbonize the economy of the region in the long term.

Assuming responsibility for emission reduction is an important part of participating in the global governance of climate change. Countries with a carbon neutrality target now cover about 75% of global greenhouse gas emissions. Carrying out fairness evaluations of their carbon neutrality targets provide a strong basis for the global carbon inventory. In this paper, the target years of carbon neutrality for major countries and regions under the global target of 2 °C and 1.5 °C are studied using the burden sharing model. On this basis, this paper simulates the possible pathways of carbon neutrality and evaluates the ambition of emission reduction targets in terms of annual emission reduction, per capita emission, and cumulative per capita emission. The results show that, from the perspective of equity, most of the developing countries cannot meet the global goal of 1.5 °C. The United States and the European Union nations could achieve carbon neutrality by 2050 by continuing their annual emission reductions under their existing NDC targets. However, to achieve carbon neutrality by 2060, China's annual emission reduction rate from 2030 to 2050 will be 6.7%, and the annual amount of emission reduction accounts for 51% of the global amount under the 1.5 °C target. Meanwhile, China would become the main force behind global cumulative emissions in the following decades. Thus, the emission reduction pathways China chooses will have an important impact on global climate mitigation progress. Based on the above research conclusions, this paper proposes that developed countries and developing countries should explore bilateral or multilateral cooperation in technology and finance in the field of climate change. Under the great pressure to achieve carbon neutrality, China needs to carry out research on the overall emission reduction pathways as soon as possible and clarify the paths at the scale of sectors, industries, provinces, and time stages.

To achieve carbon neutrality, it is necessary to grasp the essence of carbon neutrality. This paper looks into a few fundamental issues of carbon neutrality, and provides an in-depth analysis from the perspectives of environmental sustainability, technological innovation, economic viability, energy security, and international cooperation. It is shown that efforts for carbon neutrality need to focus on the key carbon dioxide (CO
2 ) emissions from fossil fuel combustion. Fossil energy is considered to play a role as a short-term "ballast stone", but its attributes decide that it can hardly lead to a sustainable future, and its phasing-out is inevitable. Disruptive zero-carbon energy production and revolutionary technological innovation in its consumption are accelerating that phasing-out process; the zero-carbon-oriented carbon neutrality goal is growing more resilient to market headwinds and releasing momentum for high-quality development. Carbon capture and carbon sinks are indispensable, but they are unable to provide a satisfactory path to carbon neutrality. Carbon neutrality requires substantial capital investment, which can be provided by zero-carbon products with ever-increasing market competitiveness. Investment in high carbon fossil fuel industry can be risky. High carbon lock-in not only increases the difficulty of carbon neutrality, but also intensifies the risk of energy security, and it is difficult to avoid the risk of market crowding-out, resulting in huge amounts of capital waste. Consequently, decarbonization is the trend of the times, giving an edge on seeking international justice and a louder voice in the international community, and also the focus of market competitiveness. However, the target year for carbon neutrality in China is before 2060, indicating that carbon neutrality is not a short-term goal. Therefore, it is impossible and unnecessary to have it realized overnight. The opportunity of carbon neutrality should be well taken for quality growth of the economy and enhancement of people's well-being. Carbon neutrality is a long-term process which calls for thorough plans and step-by-step actions. It is also evident that along with energy revolution, carbon neutrality also brings revolutionary transformation of relations of production and development paradigm. [ABSTRACT FROM AUTHOR]- Published

China has made remarkable achievements in reducing carbon emissions in recent years. However, there is still much reduction room before achieving carbon neutrality. In Beijing, the capital of China, it is a strategic choice to respond to global climate change by promoting green and low-carbon development. This paper calculates the carbon dioxide emissions of key industries in Beijing and analyzes the temporal evolution trend of carbon emissions. Carbon dioxide emissions in Beijing before 2030 are predicted based on the grey prediction GM (1,1) and BP neural network model. The effects of factors of carbon dioxide emissions are discussed using the threshold regression model under different economic conditions. The results show that energy consumption intensity, GDP per capita, and the ownership of civil cars have a positive impact on carbon dioxide emissions, while the number of permanent residents and urban green space areas have a negative impact on carbon dioxide emissions. These findings of carbon emission prediction and influencing factors contribute to carbon reduction path design. Related policy implications on carbon emission reduction are put forward from the aspects of promoting industrial upgrading, accelerating the construction of advanced economic structures, optimizing transportation structures, and strengthening green building development.

China's declaration to the international community to peak CO
2 emissions before 2030 and achieve carbon neutrality before 2060 is of great significance in advancing the objectives of the Paris Agreement, and has a positive and far-reaching impact on China's high-quality development. This paper expounds on responsibilities and ambitions in tackling climate change, analyzes the high-quality development opportunities brought about by CO2 emissions peak and carbon neutrality, and discusses the net zero carbon emissions transformation in the new era of ecological civilization. This paper is of the view that development towards net zero carbon emissions provides a new impetus for building a Beautiful China, and promoting ecological civilization and green development. The essence of carbon neutrality should be correctly understood so that the world will work together to improve climate resilience. China should also deepen the understanding of the principles and methodologies of climate change economics. [ABSTRACT FROM AUTHOR]- Published

Carbon neutrality is becoming an important development goal for regions and countries around the world. Land-use cover/change (LUCC), especially urban growth, as a major source of carbon emissions, has been extensively studied to support carbon-neutral planning. However, studies have typically used methods of small-scale urban growth simulation to model urban agglomeration growth to assist in carbon-neutral planning, ignoring the significant characteristics of the process to achieve carbon neutrality: large-scale and long-term. This paper proposes a framework to model large-scale and long-term urban growth, which couples a quantity module and a spatial module to model the quantity and spatial allocation of urban land, respectively. This framework integrates the inertia of historical land-use change, the driving effects of the urbanization law (S-curve), and the traction of the urban agglomeration network to model the long-term quantity change of urban land. Moreover, it couples a partitioned modeling framework, spatially heterogeneous rules derived by geographically weighted regression (GWR), and quantified land-use planning orientations to build a cellular automata (CA) model to accurately allocate the urbanized cells in a large-scale spatial domain. Taking the Guangdong–Hong Kong–Macao Greater Bay Area (GHMGBA) as an example, the proposed framework is calibrated by the urban growth from 2000 to 2010 and validated by that from 2010 to 2020. The figure of merit (FoM) of the results simulated by the framework is 0.2926, and the simulated results are also assessed by some evidence, which both confirm the good performance of the framework to model large-scale and long-term urban growth. Coupling with the coefficients proposed by the Intergovernmental Panel on Climate Change (IPCC), this framework is used to project the carbon emissions caused by urban growth in the GHMGBA from 2020 to 2050. The results indicate that Guangzhou, Foshan, Huizhou, and Jiangmen are under great pressure to achieve the carbon-neutral targets in the future, while Hong Kong, Macao, Shenzhen, and Zhuhai are relatively easy to bring up to the standard. This research contributes to the ability of land-use models to simulate large-scale and long-term urban growth to predict carbon emissions and to support the carbon-neutral planning of the GHMGBA.

The atmospheric concentration of CO2 is steadily increasing and causing climate change. To achieve the Paris 1.5 or 2°C target, negative emission technologies must be deployed in addition to reducing carbon emissions. The ocean is a large carbon sink but the potential of marine primary producers to contribute to carbon neutrality remains unclear.Here we review the alterations to carbon capture and sequestration of marine primary producers (including traditional 'blue carbon' plants, microalgae and macroalgae) in the Anthropocene, and, for the first time, assess and compare the potential of various marine primary producers to carbon neutrality and climate change mitigation via biogeoengineering approaches.The contributions of marine primary producers to carbon sequestration have been decreasing in the Anthropocene due to the decrease in biomass driven by direct anthropogenic activities and climate change. The potential of blue carbon plants (mangroves, saltmarshes and seagrasses) is limited by the available areas for their revegetation. Microalgae appear to have a large potential due to their ubiquity but how to enhance their carbon sequestration efficiency is very complex and uncertain. On the other hand, macroalgae can play an essential role in mitigating climate change through extensive offshore cultivation due to higher carbon sequestration capacity and substantial available areas. This approach seems both technically and economically feasible due to the development of offshore aquaculture and a well‐established market for macroalgal products.Synthesis and applications. This paper provides new insights and suggests promising directions for utilizing marine primary producers to achieve the Paris temperature target. We propose that macroalgae cultivation can play an essential role in attaining carbon neutrality and climate change mitigation, although its ecological impacts need to be assessed further.

This paper presents an overview of the 2021 global energy crisis. It has been shown that a combination of post-COVID recovery, depleted fossil fuel energy reserves and extreme weather conditions led to a surge in global demand for energy. Fossil fuel energy reserves were depleted and were not sufficiently replenished due to the need to transition from fossil fuel energy to renewables. Failure to replenish fossil fuel energy reserves led to unavoidable energy shortages. Energy demand rose to unprecedented levels and the shortage could not be filled by renewables, thereby triggering the energy crisis or energy supply crunch. The energy crisis or energy crunch witnessed in the UK and some parts of Asia and Europe showed how the energy transition can have ripple effects across every corner of society. The energy crisis demonstrates, in part, that renewable energy is not yet fully developed, and is not ready to meet the ever-growing global demand for energy by households and corporates. There is need to consider calls to slowdown the energy transition until the renewable energy sector is fully developed and ready to meet the ever-growing global demand for energy. Slowing down the transition to renewables is a step in the right direction in light of recent events. [ABSTRACT FROM AUTHOR]

To avoid the potential adverse impacts of climate change from global warming, it is suggested that the target of net zero emissions should be reached by this mid-century. Thailand is aiming to achieve carbon neutrality by 2050. Since electricity generation is one of the largest producers of carbon dioxide emission, the associated emissions must be greatly reduced to achieve the targets mentioned above. Thus, new generation expansion plans must be well developed. This paper discusses the development of generation expansion plans considering Thailand's latest policies along with enhancement of the existing multi-period linear programming model, allowing new electricity generation technologies having low emissions, e.g., solar PV with battery and hydrogen blending in natural gas, to be integrated into generation expansion planning. Then, four generation expansion plans with different levels of hydrogen blending in natural gas are proposed and discussed. It is found that Thailand can achieve carbon neutrality by 2050 by promoting more use of renewable energy altogether with trade-off between land for solar PV installation and amount of hydrogen blended in natural gas. The lesson learned from this study provides crucial information about possible pathways to achieve carbon neutrality in the electricity sector for policy makers in other countries.

RARE earth metals , *ION-permeable membranes , *CARBON offsetting , *CLIMATE change , *LIQUID membranes - Abstract
[Display omitted] • Review of advanced electrodialysis techniques for critical mineral recovery. • Investigation of lithium, nickel, cobalt, and rare earth elements sources. • Principles and performances of advanced electrodialysis techniques for metal recovery. • Necessity of feedstock-tailored advanced electrodialysis technologies is suggested. The global challenge of climate change and the pursuit of carbon neutrality drive the demand for clean energy technologies, increasing the need for critical minerals. However, diminishing ore quality and supply chain vulnerabilities highlight the necessity of exploring unconventional mineral sources. This paper assesses the potential of sources such as low-grade ores, brines, and secondary byproducts for extracting critical minerals, focusing on lithium, nickel, cobalt, and rare earth elements. Conventional refining techniques struggle with the complexity and low concentrations found in unconventional sources, prompting the exploration of innovative methods. Electrically driven membrane technologies, particularly electrodialysis (ED), show promise for selectively transporting metals through ion exchange membranes. The combination of functionalized membranes and advanced ED technologies offers high selectivity for specific elements, and renewable energy-based ED operations can minimize environmental impact. Recent advancements in ED, including selective ED and liquid membrane ED, demonstrate efficient recovery of critical minerals. This comprehensive review explores the principles and recent progress in ED technologies, with a focus on recovering critical minerals from unconventional sources. The paper is structured into three main sections: categorizing the properties of unconventional sources of critical minerals based on the latest literature, exploring the fundamental principles underpinning modern ED technologies, and investigating recent breakthroughs in the separation and recovery of critical minerals from unconventional sources using ED technologies. This framework highlights the potential of advanced ED technologies in efficiently processing diverse unconventional sources and adeptly retrieving critical minerals. [ABSTRACT FROM AUTHOR]

- Abstract
The impacts of climate change have become a series of important issues in global public health and environmental governance. As a major developing country with carbon emissions, China has actively participated in global climate and public health governance. The international academic research by Chinese scholars on carbon neutrality has gradually shifted from focusing on technological development to focusing on sustainability, green development, a decarbonization plan, public health and environmental governance. This study uses bibliometrics, scientometrics, and policy documents quantification to carry out a comparative study, comparing the keywords of China's national "carbon neutrality" policies from 2006 to 2021 with the keywords of international research by Chinese scholars, and analyzes the evolution of the academic and political concerns and development measures of China's carbon neutrality. It is found that in the stages of preliminary development and steady growth, China's carbon neutrality research and policy portfolio grew in an orderly manner, and the influence of policy and the promotion of academic research gradually strengthened. After 2020, with the outbreak of the COVID-19, national policies and carbon neutrality research began to focus on green development and public health issues, and the intersections of policy keywords and academic keywords increased. Overall, the focus of Chinese scholars on carbon neutrality research and policy is gradually approaching and integrating, and the degree of interaction and integration between academia and politics is increasing. Under the complex situation of China's decarbonization plans, climate changes, COVID-19, and international political and economic changes, China's policy design and development model are conducive to public health, green development, and innovation transformation, and building a community with a shared future for mankind.

CARBON offsetting , *CLIMATE change ,CHINA-United States relations ,PARIS Agreement (2016) - Abstract
The United States (U.S.) and China are key to meeting the goals of the Paris Agreement and reaching carbon neutrality by around mid-century. Despite differences, carbon neutrality will be met more rapidly if the two countries coordinate and facilitate synergies in carbon-neutral technologies and policy development and implementation. Building on long-term pathway models in the U.S. and China, current emissions trends and sources, and a policy analysis, this paper puts forward a novel framework for U.S.-China coordination on carbon neutrality. The analysis reveals similar technology and policy pathways, policy gaps, and shared milestones for decarbonization in 2030, 2040, and 2050-2060. The main technological pathways focus on reductions in energy demand and non-energy-related CO2 emissions, decarbonization of electricity and fuels, and increases in electrification rates and CO2 sequestration. Given existing domestic policies and opportunities for further action, areas for coordination on carbon neutrality include common policy milestones; dialogue and technical exchange; research, development, and demonstration (RD&D); and international climate leadership. Despite escalated tensions between the U.S. and China, and challenges for climate cooperation, coordination between both countries on carbon neutrality is both possible and necessary. Carbon neutrality will be met more swiftly if the U.S. and China coordinate and facilitate synergies in carbon-neutral technologies and policy. Despite the rise in geo-political tensions between the U.S. and China, coordination on carbon neutrality is both possible and necessary. An analytical framework for U.S.-China coordination on carbon neutrality, includes technology and policy pathways, and common milestones of key sectors' decarbonization for 2030, 2040, and 2050-2050. The two countries could coordinate on common policy milestones, dialogue and technical exchange, research and development, and international climate leadership. [ABSTRACT FROM AUTHOR]

- Abstract
Based on the assessment report of the Intergovernmental Panel on Climate Change (IPCC) and recent research literatures, from the perspective of the impacts and risks of climate change, this paper attempts to interpret several climate tipping points that may be exceeded due to global warming and explain mitigation measures such as carbon dioxide emission peak and carbon neutrality taken by the international community. The importance and urgency of adaptability research in different systems or regions are discussed. The main conclusions are as follows: ① In the past century, especially since the 1970s, global warming has been increasing rapidly, while the warming rate of Chinas land and sea is higher than that of the global average. ② In 2019, the atmosphere concentration of CO2, the main driver of global warming, has reached 410.5 ppm, which was 148% of the pre⁃industrial (1750) level and the highest at any time for at least 2 million years. ③ The risks of climate change will increase disproportionately as global temperature quickly increases. The climate tipping points (thresholds) of some systems may be exceeded or occur earlier than expected, causing abrupt and irreversible changes. ④ With the increase of global warming, nine global climate tipping points may being exceeded, including large⁃scale bleach⁃ ing and death of warm water coral reefs, accelerated melting of Greenland and Antarctic ice sheets, slowdown of the Atlantic Meridional Overturning circulation, etc., and there is also a risk of domino effect. ⑤ In order to address the impacts and risks of climate warming, it is necessary to limit global temperature rise in this century to 2 ℃ (preferably 1.5 ℃) above pre⁃industrial levels (1850-1900). Com⁃ pared with 2010, the global net anthropogenic CO2 emissions need to be reduced by about 25% (45%) by 2030 and achieve carbon neu⁃ trality in around 2070 (2050). ⑥ Taking warm water coral reefs as an example, this paper discusses and analyzes that the tipping point of damaged coral reefs in China may be firstly exceeded due to the high warming rate of the China Seas. Therefore, it is urgent to restore and strengthen the climate resilience of different systems or regions such as damaged coral reefs, so as to improve their ability to adapt to climate change. In addition, a breakthrough has recently been made in the research on in situ sexual reproduction and restoration of damaged coral reefs in China, which provides a positive prospect for reconstructing the resilience of damaged coral reefs.

- Abstract
Climate change is one of the most urgent challenges facing the world. All countries should take joint actions to achieve the goal of carbon neutrality, which include controlling global warming to within a 1.5 °C temperature rise, to mitigate the extreme harm caused by climate change. However, ways in which to achieve economically and environmentally sustainable carbon neutrality are yet to be established. Carbon neutrality appears frequently in international policy and the scientific literature, but there is little detailed literature. It is necessary to conduct an in-depth analysis of the development context of its research. This paper analyzed the literature on carbon neutrality using bibliometric methods. A total of 1383 research papers were collected from the "Web of Science core database" from 1995 to 2021. Descriptive statistical analysis and keyword co-occurrence and literature co-citation network analyses were utilized to sort the research hotspots, and the detected bursts, the top 30 keywords in terms of word frequency, and 12 clusters were selected. It was found that the existing carbon neutrality research literature mainly focuses on carbon neutrality energy transformation, carbon neutrality technology development, carbon neutrality effect evaluation, and carbon neutrality industry examples. The analysis process involved comprehensively reading the key articles and considering the co-citation, burstiness, centrality, and other indicators under clustering; the carbon neutrality research was then divided into three stages, and evolving themes were observed. Based on the burst detection, this paper holds that with the energy structure transformation, energy consumption assessment and carbon neutrality schemes of various industries, carbon dioxide capture technology, and biogas resource utilization, urban carbon neutrality policy will become a research hotspot in the future. This paper helps to provide a reference for scholars' theoretical research and has important reference value for policymakers to formulate relevant policy measures. It is helpful for enterprises to make strategic decisions and determine the direction of technology, for R&D and investment, and it is of considerable significance to promote the research of carbon neutrality technology.

The urgent need to address climate change has led to global efforts towards achieving carbon neutrality. However, it is crucial to recognize the existence of carbon inequity, where certain regions or communities bear a disproportionate burden of carbon emissions compared to others. This paper explores the concept of carbon inequity and highlights the importance of considering driving factors in the pursuit of just energy transition. By examining the socioeconomic, environmental, and policy-related factors that contribute to carbon emissions, a comprehensive understanding of the underlying causes of carbon inequity is gained. The study emphasizes the need to address systemic issues such as economic development patterns, industrial structures, energy consumption habits, and social inequalities that perpetuate carbon inequity. It further discusses the significance of collaborative and inclusive approaches to carbon reduction, focusing on bridging the gap between regions with high and low carbon emissions. Policy implications are derived to guide decision-makers in formulating effective strategies for achieving carbon neutrality while ensuring equity and fairness. By considering both the overarching goal of carbon neutrality and the distributional aspects of carbon emissions, a more holistic and equitable approach can be adopted to accelerate the transition to a sustainable and low-carbon future. • It is crucial to recognize the existence of carbon inequity to address climate change. • This paper explores the concept and importance of carbon inequity of just energy transition. • Policy implications are derived to guide decision-makers while ensuring equity and fairness.

Food supply chains hold significant embodied carbon emissions that need to be mitigated and neutralized. This study aimed to explore the historical Greenhouse Gas (GHG) emissions associated with household food consumption at a local scale i.e. across the eight English regions and the four nations that comprise the United Kingdom (UK). UK EatWell guidelines were used to explore the potential change in emissions and food costs in a scenario of transitions to healthier diets across the study areas. These emissions were calculated based on food consumption data before the advent of the Covid-pandemic i.e. between the years 2001 and 2018. Spatial data analysis was used to explore if the study areas had any significant correlations with respect to the emissions during the study period. The results displayed a potential reduction in GHG emissions for all study areas in the explored scenario. Further impacts include a reduction in household food costs across a majority of the areas during the study period. However, a consistent trend of significant correlations among the study areas was absent. This study concludes that local or regional policymaking should take precedence over national regulations to achieve healthier diets that are both carbon-neutral and affordable for the households.

UNITED States climate change policy ,CLIMATE change mitigation ,ENVIRONMENTAL justice ,CLIMATE change ,PUBLIC opinion ,GOVERNMENT policy on climate change - Abstract
The Biden administration has revitalized the United States' climate agenda. Current research on the U.S. climate mitigation policies has predominantly focused on individual policies and legislative measures, demonstrating a lack of a comprehensive and systematic analysis. To address this gap, this study establishes a systematic analytical framework for US climate mitigation policies, including the "Vertical Policy Hierarchy - Horizontal Policy Path - Policy Instruments" dimensions, drawing upon first-hand policy data to thoroughly assess the U.S. climate mitigation policy system, pathways, instruments, and potential policy outcomes. The study finds that, (i) Concerning the vertical policy hierarchies based on the government's governance structure, the U.S. federal government has been proactive in advancing climate mitigation policies. However, the government faces multiple risks arising from various factors, including elections, public opinion, limited authority, frequent economic and social unrest, and the ever-shifting domestic and international political factors. These vulnerabilities may undermine the effectiveness of policies. The Congress also encounters certain challenges of significant fragmentation and influence from diverse economic and political factors, which poses challenges to the enactment of related environmental legislation. Moreover, the Supreme Court's climate litigation rulings tend to exhibit a conservative and highly politicized nature. (ii) In terms of the horizontal policy path, which is categorized into six major focus areas, the U.S. climate mitigation policies have made positive strides in the general sector, buildings sector, transport sector, and agriculture and forestry sector. However, challenges persist in the energy sector and industry and business sector. (iii) An analysis of 706 policy instruments indicates that Financial/Fiscal Mechanisms and Direct Investment are the primary means of implementing U.S. climate mitigation policies. Since President Biden assumed office, Regulatory Reform has emerged as a significant breakthrough, accompanied by the gradual adoption of Commercialization Mechanisms and Governance Mechanisms. However, Market-based Mechanisms have encountered challenges in their implementation at the federal level. (iv) An analysis of the potential effects of policy instruments indicates that institutional requirements are a primary consideration; policy design emphasizes environmental justice and equity. Many policies demonstrate positive outcomes in terms of environmental effectiveness, economic effectiveness, and innovation. Policies are also beneficial in improving people's livelihoods, reducing inflation, increasing employment, while also exhibiting positive synergies and enhancing competitiveness. Combining these results and issues, this paper also discusses prominent trends in the policy and offers recommendations for climate decision-making in the United States and other countries.

The most discussed topics in the 21st century at the global level include climate change, carbon neutrality, digitization and globalization. They have impact on the lives of all people, the quality of the environment in which we live, the health of the whole population, the development of cities and urban areas, the development and direction of industry and its new technologies, and last but not least, they shape humanity to which they are giving direction. Regional self-governments, as elementary elements of the state, therefore play a key role in achieving the EU’s environmental and climate change goals and objectives. The issue of digitization is changing human approaches to address global challenges, including the call for a proper assessment of the impacts of climate change on urban and suburban areas as a tool for identifying and subsequently integrating early actions. Digital technologies and their potential can make a huge contribution to sustainable development, and to re-addressing global challenges. According to the OECD, in an era of digitization, climate change and ageing, it is important to see cities as engines for economic growth.

The intensification of global climate change has led to a widespread consensus on carbon reduction, with the power industry being the principal contributor to carbon emissions necessitating an inevitable transition of its energy structure. Concomitantly, the escalating frequency of natural disasters caused by extreme weather presents formidable challenges to both secure power supply and the low-carbon transition of the power system. To fulfill the developmental requirements of a low-carbon power system and address the carbon emission risks imposed by natural disasters, this paper proposes a bi-level model for generation expansion planning (GEP) that incorporates constraints on the carbon emission trajectory and the influence of natural disasters. The planning-level model optimizes investment costs of various generation technologies and energy storage (ES), as well as the overall operational expenses over the planning period, with an objective to minimize them. It incorporates carbon emission trajectory constraints and policy constraints, such as carbon peaking, carbon neutrality and renewable energy (RE) penetration rates, in order to optimize the planning installed capacity of power sources. The operational-level model aims to minimize typical daily operating costs while also simulating power unit outputs in routine and disaster scenarios. A case study is conducted in a disaster-prone province in southern China to analyze the power generation expansion planning and the trajectory of carbon emissions from 2020 to 2060 under different scenarios. The simulation results show that compared to thermal power, the planning scheme mainly focused on RE with ES is better suited to achieve the goal of a low-carbon transition of the power grid. Moreover, after considering natural disasters, the cost and carbon emissions of power system planning are higher, and the risk of carbon emissions increases with the severity of disasters. • A multi-time scale bi-level low-carbon GEP model is proposed. • Natural disaster scenarios and low-carbon policy constraints are considered in the GEP model. • Carbon emission trajectory of the planned power system is estimated and introduced as a constraint into the GEP model. • Evaluation indicators that comprehensively consider low-carbon performance and economic feasibility are proposed.

• A CGE model elaborately depicting six CCS technologies was developed. • Impacts of four CCS incentive scenarios on decarbonization pathways were simulated. • CCS can sequester 960 ∼ 1,604 MtCO 2 annually in China by 2060 with policy incentives. • CCS incentives can reduce China's future primary energy demand by 7.7 ∼ 17.4 %. • CCS incentives can increase GDP by 5.64 ∼ 6.59 % compared to no policy scenario. Carbon capture and storage (CCS) technology, considered as a pivotal tool in mitigating climate change within the fossil energy system, particularly in China, has experienced slower development than expected. The exploration of direct incentive policies to facilitate its growth remains relatively underdeveloped. This study developed a hybrid dynamic computable general equilibrium (CGE) model to simulate the substantial impacts of CCS incentive policies on China within the context of carbon neutrality target. Two potential incentive policies, carbon emission trading system (ETS) and 45Q tax credit, were simulated, with different sectoral coverage. The results indicate that CCS technologies can reduce carbon emissions by 960 ∼ 1,604 MtCO 2 annually by 2060 through the strategic implementation of these incentive policies. The 45Q tax credit demonstrates its effectiveness in promoting early-stage research and development (R&D) and demonstration of CCS, while the ETS policy facilitates the commercial development of CCS in the later stage of development. By 2060, the implementation of CCS incentive policies could potentially result in 7.7 ∼ 17.4 % reduction in China's primary energy consumption, 71.2 ∼ 82.7 % decrease in the carbon price of ETS and 5.64 ∼ 6.59 % increase in the GDP compared with the no-policy scenario. In addition, the sectoral output in various sectors and the welfare of urban and rural households also increase. This paper provides an important reference for the realization of China's carbon neutrality goal and the model framework can be applied to other countries. [ABSTRACT FROM AUTHOR]

- Abstract
Introduction: The effect of environmental regulations or green policies on the financial health of businesses is still up for debate. The Prime Minister of India presented a bold plan to achieve net-zero emissions by 2070 at the COP26 climate summit in Glasgow (UK). Following this announcement, numerous Indian companies voluntarily committed to becoming carbon neutral to support the ambitious emission reduction targets. A growing body of research examines the link between environmental standards compliance and businesses' sustainability measures, and how they affect their overall performance (profitability, stock returns, or output generation). Purpose: The research assesses the effect of these voluntary announcements on the stock performance of Indian companies in the context of voluntary commitments to reduce carbon emissions. Methodology: Concentrating on the announcement impact of carbon neutrality commitments/carbon emissions reductions of 52 Indian companies, the study considers carbon neutrality pledges/carbon emissions reduction from 2018 to 2022. The sample companies list was taken from various indices on the National Stock Exchange. A standard event study methodology is applied to compute abnormal returns during the event window of (−10, 10). Findings: The results show that companies announcing the carbon neutrality pledges/carbon emissions reduction received significantly negative abnormal returns of 0.49% on announcement day. The cumulative average abnormal returns for different windows are also negative. It signifies that investors don't value the environmentally sustainable actions of firms. It may also be because of investors' ignorance of carbon neutrality pledges and their importance, highlighting the need to educate investors about the significance of corporate sustainability initiatives.

Purpose: We conduct a multidisciplinary systematic literature review on climate neutrality in the supply chain. While carbon neutrality has gained prominence, our study argues that achieving carbon neutrality alone is not enough to address climate change effectively, as non-CO
2 greenhouse gases (GHG) are potent contributors to global warming. Design/methodology/approach: We used multiple databases, including EBSCO, ProQuest, Science Direct, Emerald and Google Scholar, to identify articles related to climate neutrality in the context of non-CO2 gases. A total of 71 articles in environmental science, climate change, energy systems, agriculture and logistics are reviewed to provide insights into the climate neutrality of supply chains. Findings: We find that, in addition to CO2 , other GHG such as methane, nitrous oxide, ozone and fluorinated gases also significantly contribute to climate change. Our literature review identified several key pillars for achieving net-zero GHG emissions, including end-use efficiency and electrification, clean electricity supply, clean fuel supply, "GHG capture, storage and utilization," enhanced land sinks, reduced non-CO2 emissions and improved feed and manure management. Originality/value: We contribute to the literature on climate neutrality of supply chains by emphasizing the significance of non-CO2 GHG along with CO2 and highlighting the need for a comprehensive approach to climate neutrality in addressing climate change. This study advances the understanding of climate neutrality of supply chains and contributes to the discourse on effective climate change mitigation strategies. It provides clear future research directions. [ABSTRACT FROM AUTHOR]- Published

Background: Global climate change is one of the major challenges facing the world today, and forests play a crucial role as significant carbon sinks and providers of ecosystem services in mitigating climate change and protecting the environment. China, as one of the largest developing countries globally, owns 60% of its forest resources collectively. Evaluating the carbon sequestration cost of collective forests not only helps assess the contribution of China's forest resources to global climate change mitigation but also provides important evidence for formulating relevant policies and measures. Results: Over the past 30 years, the carbon sequestration cost of collective forests in China has shown an overall upward trend. Except for coastal provinces, southern collective forest areas, as well as some southwestern and northeastern regions, have the advantage of lower carbon sequestration costs. Furthermore, LSTM network predictions indicate that the carbon sequestration cost of collective forests in China will continue to rise. By 2030, the average carbon sequestration cost of collective forests is projected to reach 125 CNY per ton(= 16.06 Euros/t). Additionally, there is spatial correlation in the carbon sequestration cost of collective forests. Timber production, labor costs, and labor prices have negative spatial spillover effects on carbon sequestration costs, while land opportunity costs, forest accumulation, and rural resident consumption have positive spatial spillover effects. Conclusion: The results of this study indicate regional disparities in the spatial distribution of carbon sequestration costs of collective forests, with an undeniable upward trend in future cost growth. It is essential to focus on areas with lower carbon sequestration costs and formulate targeted carbon sink economic policies and management measures to maximize the carbon sequestration potential of collective forests and promote the sustainable development of forestry.

CARBON emissions ,ARTIFICIAL intelligence ,CARBON offsetting ,CLIMATE change ,SPORTS competitions ,CARBON cycle - Abstract
Introduction: Carbon neutrality has become a key strategy to combat global climate change. However, current methods for predicting carbon emissions are limited and require the development of more effective strategies to meet this challenge. This is especially true in the field of sports and competitions, where the energy intensity of major events and activities means that time series data is crucial for predicting related carbon emissions, as it can detail the emission patterns over a period of time. Method: In this study, we introduce an artificial intelligence-based method aimed at improving the accuracy and reliability of carbon emission predictions. Specifically, our model integrates an Improved Mahjong Search Algorithm (ISSA) and GRU-Transformer technology, designed to efficiently process and analyze the complex time series data generated by sporting events. These technological components help to capture and parse carbon emission data more accurately. Results: Experimental results have demonstrated the efficiency of our model, which underwent a comprehensive evaluation involving multiple datasets and was benchmarked against competing models. Our model outperformed others across various performance metrics, including lower RMSE and MAE values and higher R2 scores. This underscores the significant potential of our model in enhancing the accuracy of carbon emission predictions. Discussion: By introducing this new AI-based method for predicting carbon emissions, this study not only provides more accurate data support for optimizing and implementing carbon neutrality measures in the sports fi eld but also improves the accuracy of time series data predictions. This enables a deeper understanding of carbon emission trends associated with sports activities. It contributes to the development of more effective mitigation strategies, making a significant contribution to global efforts to reduce carbon emissions. [ABSTRACT FROM AUTHOR]
