Insulating paper is the key material utilized in ultra-high voltage (UHV) projects, and it affects the safe and stable operation of the whole power system. Cellulose fiber-based insulating paper, having the advantages of low price and environmental friendliness, has been widely used as the preferred insulating material for certain transformers. Bamboo, as a fast-growing raw material, has a favorable fiber length and its carbon sequestration is better than that of wood. Bamboo can be potentially used as a new raw material for insulating paper, thus promoting the green development of the power and paper industry. This article mainly discusses the challenges and potentials of bamboo fiber-based insulating paper and the opportunities of bamboo fiber-based paper materials.

People often think of paper as an environmentally harmful product because trees are cut down to make it. A new generation that has grown up in today’s digital society may think that the use of digital devices is a waste-free way to protect our environment. Although the pulp and paper industry is making various efforts to preserve the environment, it has not been properly recognized. Developing new technologies to produce better products at lower cost while protecting our environment is important. But it is also important to enhance the image of the pulp and paper industry in the eyes of the public. The pulp and paper industry’s efforts to reforestation for raw materials and to expand the recycling of waste paper should be more widely introduced.

Waste paper disposed in landfills notably contributes to greenhouse gas (GHG) emissions and impedes more sustainable, circular alternatives, such as recycling. In Hong Kong, this unsustainable approach is currently dominant as 68% of waste paper products are treated in landfills in 2020. To contextualize the impact of local waste paper management and explore mitigation potentials of circular alternatives, this paper develops a quantitative assessment framework around GHG emissions development trajectories. Combining guidelines of the Intergovernmental Panel on Climate Change (IPCC), national GHG inventories, and local parameters from life cycle analysis, five GHG emissions projections were simulated along the Shared Socioeconomic Pathways (SSPs) until 2060. Most recent baselines indicate that Hong Kong's current waste paper treatment generated 638,360 tons CO 2 -eq in 2020, comprising 1,821,040 tons CO 2 -eq from landfill and 671,320 tons CO 2 -eq from recycling, and −1,854,000 tons CO 2 -eq from primary material replacement. Proceeding along a Business-as-Usual scenario under SSP5, GHG emissions will dramatically increase to a net 1,072,270 tons CO 2 -eq by 2060, whereas a recycling-intensive scenario will lead to a net saving of −4,323,190 tons CO 2 -eq. To complement the quantitative evidence on the benefits of waste paper recycling, field research was conducted to explore the feasibility of circular policy innovation from the perspective of recycling stakeholders. These empirical qualitative and quantitative findings from stakeholders' business routines and material transactions provide crucial indications for policy and institutional innovation: Essentially, for Hong Kong to improve waste paper recycling capacities and facilitate a circular economy (CE), local stakeholders require support via fiscal policy measures (financial subsidies or tax reductions) and infrastructure improvements (delivery access and material storage). In sum, this study employs a novel analytical framework combining original qualitative and quantitative evidence to provide policy innovation towards circular, GHG emission-saving waste paper management. [Display omitted] • A new framework assessing greenhouse gas emissions from waste paper treatment. • Exploring long-term carbon neutrality pathways for managing waste paper. • Using empirical evidence from recycling stakeholders for circular policy innovation.

Paper products are carbon-intensive and having a huge potential for carbon reduction due to their biomass-oriented characteristics. A uniform standard for total carbon footprint (CF) accounting is vital. However, the existing standards have not yet been unified. Inconsistencies between standards cause difficulties in their use and significantly weaken the credibility and comparability of the carbon footprint of a product (CFP). This work rethought the three most widely used standards (Publicly Available Specification 2050 (PAS2050), Product Life Cycle Accounting and Reporting Standard (GHG Protocol), and Product Life Cycle Accounting and Reporting Standard (ISO14067)) from the life-cycle perspective, and established a more appropriate and comprehensive CF accounting standard for paper products (CFASPP). Sanitary pads were selected as a case study to illustrate the discrepancies between PAS 2050, the GHG Protocol, ISO 14067, and CFASPP, for which the annual production CF results were 1424.60, 1481.08, 1453.57, and 1427.04 tons of carbon dioxide equivalent (CO 2 e) respectively. The main reasons for the different CF results were the cut-off criteria and the inclusion or exclusion of carbon storage, delayed emissions, and energy recovery. Each element increased or decreased 22.57 (carbon storage), 29.96 (cut-off criteria), 10.4 (delayed emissions), and 27.52 (incineration with energy recovery) tons of CO 2 e in the results. With increasing demand, these discrepancies will become increasingly significant and may lead to corporations shouldering more or less carbon emission responsibilities by selecting different standards, which will challenge the fairness of product carbon neutrality management. CFASPP covers all paper product life-cycle stages and places greater emphasis on the aspects of carbon storage, delayed emissions, and energy recovery in incineration, which cannot be ignored for the CF accounting of paper products and other biomass-oriented products. This study aims to provide a more applicable and comprehensive guide for corporations to evaluate the CF of paper products, and to provide a reference for the construction of a carbon-neutral evaluation system.

The pulp and paper industry, which provides cellulose pulp and paper, bio-based energy and chemicals, is one of the largest energy consumers, greenhouse gases (GHG) and pollutant emitters among manufacturing industries. Although the environmental impact of the pulp and paper industry has been extensively studied, life cycle assessment (LCA) results have not yet reached a consensus. By means of a systematic review and meta-analysis, this article contributes to the quantification and harmonization of the life cycle environmental impacts of pulp making and paper making systems. Based on the screening of 45 cases of paper making and 18 cases of pulp making, we found that 1 t of paper results in about 950 kg carbon dioxide (CO2) equivalent (CO2-eq) GHG emissions on average. However, there are distinct differences between countries and pulp and paper categories. The dominant factor influencing GHG emissions is energy use. In paper making, the pulp making process is responsible for 62% of energy use, 45% of GHG emissions, 48% of acidification potential, and 49% of eutrophication potential. The kg CO2-eq emissions of three different types of pulp were as follows: Kraft, 508 kg CO2-eq/t; chemi-mechanical, 513 kg CO2-eq/t; and recycled pulp, 408 kg CO2-eq/t. Excluding emissions from electricity and steam production, the convergence of carbon emissions is observed within the same categories of pulp. Straw-based pulp caused far more environmental impact than any other type because of the intensive inputs in agricultural activities as well as in the pulp making process. This research highlighted the inconsistencies in functional units, system boundaries, and methodologies and carbon neutrality assumptions in different LCA studies of pulp and paper making. Future studies should focus on the environmental impact of straw-based pulp making, system boundary unification, and calculation of biogenic carbon emissions.

Small modular reactors (SMRs) are small-scale reactor designs (< 300 MWe), generally planned for deployment as multi-module nuclear power plants. Due to their small size, SMR modules could be manufactured in a factory and deployed to a site via truck or rail for installation and fueling. SMRs are being evaluated for their ability to provide both power and steam, such that they could be a viable replacement for fossil fuels. SMRs have been considered for coupling to manufacturing processes in addition to being connected to the grid, allowing them to follow the net grid demand in a “load following” operational mode during times of high renewable generation. Alternately, SMRs could be used to replace cogeneration and combined-cycle processes at manufacturing plants which utilize natural gas and other fossil fuels. Idaho National Laboratory (INL) is studying the use of SMRs for large-scale manufacturing processes that require both electricity and steam. The current study examines the integration of a SMR with two mid-size pulp and paper mills in the southeastern United States. The study consists of three parts: steady-state analysis of the mill, elimination of fossil fuel use in the lime kilns, and economic analysis of the modified plant operations. A steady-state model of each mill is developed in Aspen HYSIS based on real data from the operation of each mill. The steady-state model is then modified to include the SMR while maintaining production steam quality and making as few changes to existing equipment as possible. This model gives an estimate of the minimum requirements for SMR output, as well as the change in generation by existing boilers and turbines. With an overall picture of the new plant operation and determining the number of SMR modules required, further changes are suggested to minimize or completely eliminate fossil fuel use from the plant. Apart from steam generation, the largest consumer of fossil fuels at the plant is typically the lime kilns. Conversion of the lime kilns from fossil fuel combustion to electric heating is the most feasible solution to eliminate fossil fuels. This study finds that electric lime kilns are economical when the plant has a surplus This study presents a feasible example of using an SMR as a substitute for fossil fuel cogeneration. If this approach were expanded across the manufacturing industry, it would have a significant impact on environmental emissions and air quality.

The EU has set the ambitious target of raising the share of EU energy consumption produced from renewable resources to 32% by 2030, with a target of climate neutrality by 2050. The aim of this paper is to assess the role of biomass usage in the context of these targets. The paper identifies the progress made between 2013 and 2022 by focusing on a selection of EU countries. The largest bioenergy increments of 130, 77, and 60 PJ were reported for Poland, Sweden, and the Netherlands. This study evaluates the crucial role of co-generation and heat in EU regions, with biomass usage between 55 and 80% of the combined heat and power (CHP) energy in Nordic countries. The future perspectives for bioenergy based on EU policies, biomass resources, and technical issues were addressed. The EU possesses around 9% of the global biomass supply, ensuring a certain level of biomass resource dependence. Thus, the biomass usage demand in energy production, non-energy sectors, and transport is expected to rise, leading to increments of 13–76% on biomass imports. It appears that bioenergy development is mostly limited by economic issues and uneven support for bioenergy in different EU countries as well as environmental issues. The study shows a promising and sustainable potential of bioenergy in the EU as a renewable energy source while minimizing negative impacts on the environment and the economy. By 2050, liquid biofuels are likely to be increasingly used in the transport sector. Non-energy sector usage of biomass is still in an early stage of development, except for the pulp and paper industry, and significant use of biomass in non-energy sectors seems unlikely in the near future.

Global energy security is a growing worldwide concern in the presence of high economic policy uncertainty (EPU) that can be addressed by advancing sustainable energy diversification (ED) practices. Energy security can be estimated by combining ED and EPU indices; hence, this study uses a dataset covering three continents and 26 countries from 1995 to 2023 to measure energy security employing this approach. The study employs quantile regression and panel data analysis, finding a positive relationship between EPU and ED. The results reveal that when EPU increases, the spectrum of energy sources declines, negatively impacting energy security. Other factors of globalization, Gross Domestic Product, gross capital formation, and the labor force also have an impact on the spectrum of energy sources. To obtain a sustainable level of ED, policymakers should increase investment in gross capital formation because economic growth and openness via pro-global policies have less impact on ED. This study also demonstrates that labor capital shifts have a significant effect on ED. The quantitative results reveal the importance of clear and precise economic policies for increasing investment in carbon-free energy security. [Display omitted] [ABSTRACT FROM AUTHOR]

The economic feasibility of retrofitting an amine based post-combustion CO2 capture process to an existing Kraft pulp mill and an existing integrated pulp and board mill has been assessed. This study builds on the technical assessment of the energy performance of the mills when retrofitting a post-combustion CO2 capture process by Onarheim et al. (2017). Between 75 to 100% of the CO2 emissions from the pulp and paper industry originate from the combustion of biomass. If the raw material is sourced sustainably, these emissions are categorized as carbon neutral. Applying sustainably managed biomass in the pulp and paper processes and capturing the resulting CO2 for permanent storage enables the industry to go carbon negative. In this study, the economic impact of retrofitting CO2 capture from the flue gases of the recovery boiler, the multi-fuel boiler and the lime kiln were assessed. The levelized cost of pulp and the cost of CO2 avoided were evaluated based on six different scenarios varying the CO2 tax, incentives for renewable electricity production, with and without recognizing biogenic CO2 emissions as neutral (exempting CO2 emissions from tax or not), and rewarding captured and permanently stored CO2 with negative emissions credit. Results show that the pulp and paper industry has a potential for realizing feasible implementation of large-scale industrial Bio-CCS. For cases where 60-90% of total site CO2 emissions are captured, the cost of avoided CO2 amounts to 52-66/t for the Kraft pulp mill and 71-89/t for the integrated pulp and board mill. The cost of avoided CO2, and thus the realization of Bio-CCS in the pulp and paper industry, is strongly dependent on prevailing policy frameworks such as the EU ETS. In order to reach a levelized cost of pulp similar to the reference mill without CO2 capture, a negative CO2 emission credit of 60-70/t CO2 for the Kraft pulp mill and 70-80/t CO2 for the integrated pulp and board mill will be required. As long as biogenic CO2 emissions that are captured and permanently stored are not recognized as negative and rewarded accordingly there is no economic incentive for the owners of pulp and paper mills to implement CCS. The only way to get the pulp and paper industry to implement and deploy Bio-CCS will need the support of the decision-makers in promoting the right policy framework and regulations to encourage the investment such as strong incentives for negative emissions which are bankable during the long term operation of the mills.

As China puts forward its “carbon emissions peak and carbon neutrality” goals, how to achieve carbon reductions has become a key for China’s goal. The manufacturing industry is a significant source of carbon dioxide emissions. For a manufacturing country such as China, adjustments in various aspects of the industry would have a huge impact on its carbon emissions. As an important reform of the contemporary production mode, the process of production automation in China will inevitably affect China’s carbon emissions; therefore, the analysis of the impact of that production automation on the carbon dioxide emissions is an important basis for judging the future carbon reductions in China. Referring to the traditional study of the carbon Kuznets curve, this paper analyzes the impact of an average wage on production automation and the role of production automation in the carbon Kuznets curve (CKC). This paper proposes that production automation plays a mediating role in the process of carbon emissions, and gives a verification model of that mediating role. By analyzing the relationship between average wages and the production automation process, the U-shaped curve relationship between them was verified. By examining the relationship between carbon dioxide emissions data and the production automation industry in China, we verified that production automation plays a partial mediating role in the change of the carbon Kuznets curve. Combined with the analysis of the two parts, this paper believes that with the continuous development of China’s intelligent manufacturing industry, China’s carbon reduction prospects are more optimistic, and that there is a good industrial foundation to achieve the “carbon peaking and carbon neutrality” goals. Finally, this paper proposes policy suggestions so as to increase research investment in production automation, to help promote the application of production automation, encourage the research and application development of low-carbon technology, especially encouraging modular design, and to give full play to the role of production automation in the process of carbon neutrality in China.

This paper tries to explain the economic significance of “pursuing green development and promoting harmony between humanity and nature” in the Report to the 20th National Congress of the Communist Party of China (CPC) from the following eight aspects. First, it explains how to respect, adapt to, and protect nature through the confirmation of ownership, valuation classification and incentive. Second, it analyzes why China should work actively toward the goals of peaking carbon emissions and achieving carbon neutrality from the new security concept, new challenges, new situations, and new tasks brought by the urgency and severity of climate change risks. Third, it expounds on the difficulty and complexity of addressing climate change from multiple aspects, such as the ratchet effect, Giddens’s paradox, prisoner’s dilemma, lock-in effect, asset stranding, intergenerational equity, and the Wandering Earth scenario. Fourth, it recognizes the importance of stability, overall planning, and coordination based on the overall planned and coordinated triangle of high-quality development, carbon neutrality, and energy security. Fifth, it emphasizes the importance of green and low-carbon technological innovation by means of the IPAS equation. Sixth, it explains the essence of carbon neutrality as the industrial transition based on the energy transition, which is an economic logic. Seventh, taking the carbon market as an example, it explains the economic principle that the market mechanism plays an important role. Eighth, it explains how finance empowers the goals of peaking carbon emissions and achieving carbon neutrality as well as high-quality development. Finally, this paper is of guiding significance for economics, finance, international trade, and policy research, and in the meantime, provides new research tasks. [ABSTRACT FROM AUTHOR]

A transition to a carbon neutral society will require a shift from fossil to renewable resources. This will affect the conversion of biomass and related industries such as the pulp and paper industry. The purpose of this paper is two-fold: first, to describe and analyse the transformation processes in the Swedish pulp and paper industry and the adoption of biorefinery options, and second, to demonstrate how conceptualisations from strategic management can be used to describe regime destabilisation. The industry's adoption of biorefinery options has been modest so far, but there is development along two trajectories. The first centres on gasification and the second on separation and refining. Such diverging strategies in response to external pressure can be explained by differences that exist between firms. Signs of increasing firm divergence, or ‘regime fragmentation’, might indicate the entry into a phase of regime destabilisation, and a critical point in a transition.

There is a significant opportunity now for investors to build, own, and operate biorefineries at existing pulp and paper sites that will work synergistically and economically for the pulp and paper mill owner and the biorefinery owner. The pulp and paper industry is the world’s largest nonfood biomass collection system. The pulp and paper industry is a mature industry producing low-margin commodity products. But it has the ideal infrastructure, experience, and resources to capitalize on the strategic interest in renewable fuels via the biorefinery. Industry leaders, investors, policy-makers, and others are now beginning to better understand the vital role to be played by biorefineries as we move from a fossil fuel-based energy economy toward a bio-based one. When properly located and operated, the potential of an integrated forest biorefinery is expected to be huge: a very attractive and synergistic business opportunity for both the colocated pulp and paper mill and the biorefinery itself. Biorefineries are a key pathway to our biofuture, displacing fossil fuels and supplying clean, renewable, and carbon neutral energy. Biorefineries fit very well at pulp and paper mills because of their inherent ability to gather and process biomass and create energy from biomass.

Energy technologies based on biomass conversion are put forward as major means to curb climate change and enable a transition to a carbon neutral society. Many policies at international and national level are set up to support this transition. The pulp and paper industry is strongly linked to the conversion of biomass in Sweden and have a decisive role for the future of these technologies. This study aims to describe and explain the Swedish pulp and paper industry’s reaction to policy with regard to the development of biorefineries. It turns out that firms are developing along two technological trajectories; 1) gasification for fuel production with a business model similar to the current one and 2) separation and refining for production of high value products, which requires a modified business model. Firms are also repositioning themselves within the regime and across regime borders. We conclude that the regime is in a phase of fragmentation. The policy implications from this analysis are that effective policy intervention needs to consider that multiple signals that are affecting the regime and policies should be designed depending on what degree of regime fragmentation that is desirable.

- Abstract
The urgent challenge of reducing industrial greenhouse gas emissions has created a growing demand for a more comprehensive understanding of how various technology options can contribute to achieving carbon neutrality. Energy efficiency has long been regarded as a key pathway in this context, but the volume and diversity of efficiency options has resulted in an unclear understanding of their combined impacts. In this study, we present a novel technology-explicit method to estimate the overall abatement potential associated with a comprehensive suite of 115 energy efficiency technologies spanning all relevant sector processes and energy types. By applying our flexible analysis framework to a case study of the Canadian pulp and paper sector, we demonstrate that energy efficiency could be the single largest contributor to achieving a carbon-neutral target for the sector. We find that efficiency can reduce emissions by 4.92 MtCO 2 e/yr (66%) relative to business-as-usual by 2050 at a weighted average abatement cost of -$162/tCO 2 e when accounting for capital, operating, maintenance, and energy costs. Abatement at the energy system-wide level is even larger, reaching 6.67 MtCO 2 e in 2050 when accounting for upstream effects. Adoption of the full suite of efficiency measures could materially improve the competitiveness of the sector by reducing energy and carbon costs. On the whole, our results suggest that proven energy efficiency technologies could be the primary element of a credible low-cost pathway towards achieving a target of carbon neutrality for the pulp and paper sector.

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.

This paper studies the optimal vehicle fleet planning and collaboration problem for a fuel vehicle (FV) transport service provider, a commercial electric vehicle (CEV) transport service provider, and a carbon emission treatment agency under carbon neutrality. The FV transport service provider pays a fixed fee or a portion of its sales revenue to a carbon emission treatment agency in exchange for technology to reduce its carbon emissions, and it can adopt three strategies (i.e., no emission reduction, purchasing technology for emission reduction, and entrusting a carbon emission treatment agency). We derive each party's optimal fleet size, price, and profit in the three scenarios. Our results suggest that carbon emission reduction strategies may improve the market performance of the FV transport service provider. Then, we find no certain strategy is always preferable to another: the optimal cooperation strategy between the transport service provider and carbon emission treatment agency depends on the fixed technology fee, ratio of revenue sharing, government penalty, the transport service market potential, and consumer green preference, as well as the cost per CEV. This paper gives the transport service provider and carbon emission treatment agency a full picture of whether, when, and how to collaborate in green commerce. [ABSTRACT FROM AUTHOR]

Yang, Tao and Wang, Rong
- Abstract
Improving the structure of energy consumption (ECS) through green finance and the digital economy is one of the main paths to achieving the goal of carbon neutrality. This paper explores the impact of green finance and the digital economy on the ECS of 30 regions in China from 2007 to 2022 using the Generalized method of moments(GMM) model, further analyzes its heterogeneity, and then provides a reference for the scientific development of relevant decisions. The conclusions are as follows: (1) The change in the ECS is closely related to the degree of optimization of the ECS in the previous year, and this is a process of dynamic adjustment. The level of digital economy development can improve the ECS of the country as a whole and in the eastern and central regions, while the western regions have not yet played a significant role due to the underdevelopment of the digital economy. Green finance can inhibit fossil fuel energy consumption in all regions, and it promotes cleaner, more efficient, and low-carbon energy consumption, thereby improving the ECS. However, the impact effect is the largest in the east and smaller in the west. (2) The urbanization levels of the country as a whole and that of the central and western regions show a positive correlation with the results of energy consumption. However, in the eastern region, it shows an inhibitory effect on fossil fuel energy consumption, which can optimize the ECS. The industrial structures in all regions have positive impact coefficients; the development of industry is not conducive to the optimization of the ECS. Trade openness can improve the ECS only in the eastern region; technological progress in all regions can significantly improve the ECS. Based on the background of carbon neutrality, this paper reveals that green finance and the digital economy promote cleaner, more efficient, and lower carbon energy consumption and reduce the level of energy consumption. This paper also provides a reference for the scientific formulation of relevant decisions. [ABSTRACT FROM AUTHOR]

The process of carbon neutrality does have economic costs; however, few studies have measured the cost and the economic neutral opportunities. This paper uses a dynamic computable general equilibrium (CGE) model to simulate China's carbon neutrality path from 2020 to 2060 and analyzes its economic impact. This paper innovatively adjusts the CGE modeling technology and simulates the boundary of the Porter hypothesis on the premise of economic neutrality. The results show that the carbon neutrality target may reduce the annual GDP growth rate by about 0.8% in 2020–2060. To make the carbon pricing method under the carbon neutrality framework meet the strong version of the Porter hypothesis (or economic neutrality), China must increase its annual total factor productivity by 0.56–0.57% in 2020–2060; this is hard to achieve. In addition, the study finds that China's 2030 carbon target has little impact on the economy, but the achievement of the 2060 carbon neutrality target will have a significant effect. Therefore, the paper believes that the key to carbon neutrality lies in the coexistence of technological innovation and carbon pricing to ensure that we can cope with global warming with the lowest cost and resistance.

In light of international climate agreements and the Sustainable Development Goals (SDGs), there is a growing need to enhance the understanding of the linkages among land use/cover change (LUCC) and its carbon effects (CEs), as well as human well-being (HW). While existing studies have primarily focused on the impacts of LUCC on CEs or ecosystem services, there remains a gap in systematically elucidating the complex relationships among LUCC, CEs, and HW. This paper presents a comprehensive review of the nexus between land-based CEs and HW, examining: (1) the correlation between LUCC and CEs, encompassing methodologies for investigating LUCC CEs; (2) the association between CEs and HW, introducing the concept of "low-carbon human well-being" and evaluation framework; and (3) the proposed framework of "LUCC-CEs-HW," which delves into the intricate connections among three elements. The study identifies research gaps and outlines potential future directions, including assessments of LUCC CEs and low-carbon HW, exploration of the "LUCC-CEs-HW" nexus, and the development of standardized measurement approaches. Key opportunities for further investigation include establishing a unified evaluation index system and developing scalable methods. This paper elucidates the relationships among LUCC, CEs, and HW, offering insights for future works. [ABSTRACT FROM AUTHOR]

- Abstract
The present study is based on an analysis of carbon indicators in the environment during the COVID-19 pandemic period. It aims to provide an outlook for the future development of global carbon neutrality in the post- pandemic period.The research on the carbon index during the COVID-19 epidemic is a new scientific work, which is of great significance for the future development of environmental science. Therefore, it is necessary to write a review report on past events before fully conducting this study. It utilized various climate models, initially 232 papers, but eventually narrowing it down to 49 papers for the final context and examination. By examining the carbon neutrality of different phase of the pandemic (pre-pandemic, mid-pandemic, and post-pandemic), as well as considering various climate scenarios, we aim to generate diverse research findings. As the result, the epidemic has had a global impact, posing threats not only to human health and lives but also having far-reaching economic and environmental implications. In the short term, the pandemic has had some positive impacts on advancing carbon neutrality goals. However, in the long-term, it could lead to a slowdown or delay in the achieving global carbon neutrality due to various challenges. These challenges include diverting more resources towards pandemic response and reducing investment in clean energy. Pandemics contribute to global health and economic crises, necessitating significant societal resources such as medical equipment, medicines, human and financial resources to control transmission and treat infected individuals. Consequently, other vital environmental issues like climate change may be neglected or postponed. Ultimately, the financial constraints faced by many countries and businesses during the pandemic may compel them to reduce investments in clean energy as a means to save money and cut costs.

Global climate change, driven by increasing carbon emissions, has posed a significant challenge to both human survival and development, becoming a major issue for the sustainable progress of human society. This paper examines the characteristics and differences in the spatio-temporal distribution of carbon emissions and sinks across Wuhan Region that is stratified into three spatial levels: Hubei Province, the Wuhan Metropolitan Area, and Wuhan City. On a finer spatial scale within Wuhan, it uncovers the spatial correlations and disparities between carbon emissions and sinks. Accordingly, the paper proposes strategies and suggestions for reducing carbon emissions and enhancing carbon sinks at the provincial, metropolitan, and municipal levels. These findings are valuable for sustainable regional development and construction of low-carbon eco-cities. [ABSTRACT FROM AUTHOR]

This study estimates the environmental impacts of Bitcoin mining. Employing a top-down measurement approach, this paper assesses the carbon footprint of Bitcoin mining in China from 2017 to 2021. The findings reveal that mining activities during this period contributed to a total of 77.84 million tons of carbon dioxide emissions in China. By utilizing data at the provincial level, we find that the seasonal migration of Bitcoin mining pools will lead to regional power demand shocks in China. Additionally, this study predicts future carbon emissions from Bitcoin mining in China, projecting cumulative carbon dioxide emissions of 76.40 million tons and 722.18 million tons by 2030 and 2060 respectively, in the absence of any policy interventions. Based on these findings, this paper posits that governments worldwide should make efforts to restrict the carbon emissions from Bitcoin mining and opt for environmentally friendly technological methods to fundamentally alleviate Bitcoin's reliance on energy. The implication for central banks is that carbon emission should be taken into consideration when designing the central bank digital currencies (CBDCs). [ABSTRACT FROM AUTHOR]

As a new abstract computational model in evolutionary transfer optimization (ETO), single-objective to multi-objective optimization (SMO) is conducted at the macroscopic level rather than the intermediate level for specific algorithms or the microscopic level for specific operators; this method aims to develop systems with a profound grasp of evolutionary dynamic and learning mechanism similar to human intelligence via a "decomposition" style (in the abstract of the well-known "Transformer" article "Attention is All You Need", they use "attention" instead). To the best of our knowledge, it is the first work of SMO for discrete cases because we extend our conference paper and inherit its originality status. In this paper, by implementing the abstract SMO in specialized memetic algorithms, key knowledge from single-objective problems/tasks to the multi-objective core problem/task can be transferred or "gathered" for permutation flow shop scheduling problems, which will reduce the notorious complexity in combinatorial spaces for multi-objective settings in a straight method; this is because single-objective tasks are easier to complete than their multi-objective versions. Extensive experimental studies and theoretical results on benchmarks (1) emphasize our decomposition root in mathematical programming, such as Lagrangian relaxation and column generation; (2) provide two "where to go" strategies for both SMO and ETO; and (3) contribute to the mission of building safe and beneficial artificial general intelligence for manufacturing via evolutionary computation.

- Abstract
Giving full play to carbon emission reduction of green credits is essential to achieve carbon neutrality. According to low-carbon pilot policies and the condition of industrial transfer, this paper first sorts those provinces into different research zones. The zones are as follows: (Ⅰ) the first and second batch of low-carbon municipalities and the first batch of pilot provinces (L1) and other provinces (L2) and (Ⅱ) strong industry transfer-out zone (STR), weak industry transfer-out zone (WTR), and industrial transfer-in area (TIR). Then, we employ a dynamic panel data model and systematic GMM (SYS-GMM) approach to empirically test the impact of green credit and nongreen credit on carbon emissions. Further, this paper analyzes how to coordinate two types of credits to achieve carbon neutrality. The results show that, first, at the national level, the nexus of green credit and carbon emissions with an inverted U-shaped curve and the current impact of green credit is still in the first half of the inverted U-shaped stage. The achievement of carbon neutrality is associated with the ratio structure of green credit to nongreen credit and the scale of green credit. Second, the achievement of carbon neutrality is with regional heterogeneity. The achievement of carbon neutrality is associated with the scale of green credit in L2 and TIR, but also with the ratio structure of nongreen credit to green credit in L2 and STR. However, the carbon neutralization effects with green credit are insignificant in L1 WTR. Finally, based on those conclusions, this paper puts forwards some suggestions to provide references for the policy formulation of green credits and carbon neutrality. [ABSTRACT FROM AUTHOR]

Solid-state hydrogen storage technology has emerged as a disruptive solution to the "last mile" challenge in large-scale hydrogen energy applications, garnering significant global research attention. This paper systematically reviews the Chinese research progress in solid-state hydrogen storage material systems, thermodynamic mechanisms, and system integration. It also quantitatively assesses the market potential of solid-state hydrogen storage across four major application scenarios: on-board hydrogen storage, hydrogen refueling stations, backup power supplies, and power grid peak shaving. Furthermore, it analyzes the bottlenecks and challenges in industrialization related to key materials, testing standards, and innovation platforms. While acknowledging that the cost and performance of solid-state hydrogen storage are not yet fully competitive, the paper highlights its unique advantages of high safety, energy density, and potentially lower costs, showing promise in new energy vehicles and distributed energy fields. Breakthroughs in new hydrogen storage materials like magnesium-based and vanadium-based materials, coupled with improved standards, specifications, and innovation mechanisms, are expected to propel solid-state hydrogen storage into a mainstream technology within 10–15 years, with a market scale exceeding USD 14.3 billion. To accelerate the leapfrog development of China's solid-state hydrogen storage industry, increased investment in basic research, focused efforts on key core technologies, and streamlining the industry chain from materials to systems are recommended. This includes addressing challenges in passenger vehicles, commercial vehicles, and hydrogen refueling stations, and building a collaborative innovation ecosystem involving government, industry, academia, research, finance, and intermediary entities to support the achievement of carbon peak and neutrality goals and foster a clean, low-carbon, safe, and efficient modern energy system.

Chemical oxygen demand (COD) is widely used as an organic pollution indicator in wastewater treatment plants. Large amounts of organic matter are removed during treatment processes to meet environmental standards, and consequently, substantial greenhouse gases (GHGs) such as methane (CH4) are released. However, the COD indicator covers a great amount of refractory organic matter that is not a pollutant and could be a potential carbon sink. Here, we collected and analysed COD data from 86 worldwide municipal wastewater treatment plants (WWTPs) and applied a model published by the Intergovernmental Panel on Climate Change to estimate the emission of CH4 due to recalcitrant organic compound processing in China’s municipal wastewater treatment systems Our results showed that the average contribution of refractory COD to total COD removal was 55% in 86 WWTPs. The amount of CH4 released from the treatment of recalcitrant organic matter in 2018 could have been as high as 38.22 million tons of carbon dioxide equivalent, which amounts to the annual carbon sequestered by China’s wetlands. This suggests that the use of COD as an indicator for organic pollution is undue and needs to be revised to reduce the emission of GHG. In fact, leaving nontoxic recalcitrant organic matter in the wastewater may create a significant carbon sink and will save energy during the treatment process, aiming at carbon neutrality in the wastewater treatment industry.
