Achieving tourism carbon neutrality is essential for sustainable tourism development. This paper uses the coupled coordination distance model, modified gravity model and social network analysis to attempt to construct a nationwide tourism carbon neutral spatial network to clarify the role of each province in the process of achieving China's tourism carbon neutrality. The results show that: (1) only seven provinces will achieve tourism carbon neutrality in the target year of carbon neutrality in China (2060). (2) From 2001 to 2060, most provinces are at the stage of coordinated development of tourism carbon emissions and tourism carbon sinks, but the degree of coordinated development is low. (3) The structure of China's tourism carbon-neutral spatial network tends to be looser from 2001 to 2060. As the time series progresses, the role of each province in the spatial network will be gradually clarified. (4) In the process of achieving the goal of China's tourism carbon neutrality, the number of tourism carbon sink input areas is much larger than that of tourism carbon sink output areas. Accordingly, this paper proposes countermeasures from three aspects: government-led, market system and voluntary mechanisms, in order to promote the achievement of China's tourism carbon neutrality goal.

Financial development (FD) is pioneered to solve the problem of vital capital supporting for carbon neutrality. Detecting the effect of FD on carbon emissions (CE) plays an important role in accurately planning FD, and guiding carbon neutrality in China. To clarify the influence of FD on CE and the underlying pathways concerning scale effect, structural effect, and technological effect, this paper use China’s 285 city-level data spanning 2003–2016 and fixed effect (FE) models and instrumental variable (IV) methods to test the effect of FD on carbon neutrality in China. The findings show that (1) the development of financial deepening, financial interrelation ratio, and financial intermediary all prompt carbon emissions at the national level. (2) Regional heterogeneity indicates that FD benefits carbon neutrality in mid-Western cities but fails in eastern cities. (3) FD increases carbon emissions by boosting electricity consumption but decreases carbon emissions by promoting structural optimization and technological progress. (4) Environmental regulations partially curb the carbon emissions effect of FD. This paper proposes some suggestions to reduce CE and gain carbon neutrality in China by greening FD, optimizing industrial structure, promoting technologi)cal innovation and strengthening environmental regulation.

The existing millennium documents the most adverse consequences of global warming which in contrast to pre-industrial era are more devastating. Thus, these prevailing consequences raise numerous concerns regarding the well-being of future and current generation. Scholars, in this regard, are putting efforts punctiliously towards methods that could halt the surging emissions. This paper also attempts to contributes to existing literature by reporting the empirical evidences regarding the role of energy transition technologies, renewable energy production (REP), trade openness, green investment, and carbon taxes in carbon neutrality in Chinse economy covering the time span of 1980–2020. By employing Dynamic Auto-regressive Distributed Lags (DARDL) model to check the association, findings exposed that electricity production from water sources, electricity production from solar sources, REP, trade openness, green investment, and carbon taxes are negatively correlated with CO2 emissions. Study offers policymakers a help in formulating policies related to achieve carbon neutrality using renewable sources of energy production, carbon taxes, and green investment. [ABSTRACT FROM AUTHOR]

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]

In the context of carbon peaking and neutrality, it would be interesting to study the policy conditions for achieving carbon targets. From a technical perspective, this study constructed a theoretical model of the relationship between energy tax policy, R&D subsidy policy, and energy intensity within the framework of biassed technical change. Subsequently, through the logical relationship between energy and carbon intensities, three combination policy schemes for achieving the carbon intensity target were obtained. The findings are as follows: First, a higher rate of energy tax and R&D subsidy is destined to lead to a lower energy intensity, and energy tax policy can better boost energy intensity than R&D subsidy policy. Second, in terms of pulling the carbon intensity, the effect of the energy tax policy is better than that of the R&D subsidy policy, but in terms of its impact on the future policy effect, the R&D subsidy policy is better than the energy tax policy. Third, China should adopt a combination of policies to reduce carbon intensity, with a certain increase in the energy tax policy and a certain increase in the R&D subsidy rate policy.

Building a new type of power system with wind and solar as the dominant body of sources is expected to play the key role for China to achieve carbon neutrality. Transiting from the fossil fuel dominating power system to a renewable dominating system requires both the technology progress and the institutional changes. The total direct investment cost of China's power system decarbonization is estimated to be about 67.6 trillion yuan, which consists of new wind and solar power capacity, energy storage facilities, and transmission lines. The electricity storage technology is the key factor to affect the transitional costs. Meanwhile, institutional changes are needed to adapt to the high penetration of wind and solar to cope with the new challenges the renewable brings, namely the flexibility, adequacy and affordability. China's market-oriented reform should move to the direction of establishing a real unified national market system to achieve the integration of high percentage of renewables. [ABSTRACT FROM AUTHOR]

Carbon neutrality is one of the key issues in mitigating global climate change. The carbon neutrality process accelerates the global energy transformation from fossil energy to renewable energy. Among the main indicators related to carbon neutrality proposed by the Chinese government, those directly related to energy include carbon emission intensity, the proportion of nonfossil energy consumption, and the total installed capacity of wind and solar power generation. It can be seen that the transformation of energy development is crucial for realizing carbon neutrality. Meanwhile, the correlation between carbon neutrality and economic development is not antagonistic. On the contrary, carbon neutrality can not only enhance the quality and efficiency of traditional industries but also improve the overall development of society. Therefore, the coordinated and sustainable developments of the energy - economy-environment (3E) system is the priority for achieving the target of carbon neutrality. However, the impact of carbon neutrality on regional development requires long-term consideration, which increases the difficulties of comprehensive planning. In this study, a long-term comprehensive programming model of regional energy and economic development under carbon peaking and carbon neutrality targets was established. A carbon neutrality assessment indicator (CNAI) framework was constructed to assess the effect of carbon neutrality actions in different regions. Meanwhile, a LEAP model was developed to simulate energy demand and carbon emissions. The multi-target weights determined by assessment results of CNAI and the parameters range set by LEAP model were the basis of the multi-objective optimization model to support regional development. Furthermore, the proposed method was applied to Shaanxi province in China, which offered quantitative targets and suggestions for energy structure transformation and industrial structure adjustment. The results show that coal and oil will account for 6.25% of the total energy consumption and the proportion of secondary industry will drop to 25.40% by 2060. The method established in this study provides a new scientific approach for resolving multi-objective trade-offs in long-term programming and determining a reasonable optimization range for regional development under climate mitigation policies.

China has announced its goal of reaching carbon neutrality by 2060, which will have a profound impact on its energy and economic systems. During this process, the power sector will play a key role in helping the country on its road towards carbon neutrality. This study develops a multi-regional power dispatch and capacity expansion model to combine long-term capacity expansion with short-term power dispatch. The model is built to optimise the carbon-neutral transition pathway from the perspective of economics, focussing on power system stability and reliability under high penetrations of renewables. Using the case study of North China, the cost-effective methods for power system transitions under the targets of reaching peak emissions by 2030 and achieving carbon neutrality by 2060 are discussed under different scenarios. We find that the future power supply system will rely heavily on renewable energy which will account for more than 89% of power generation. Inner Mongolia will produce more than 84% of power in the North China region. The inter-regional power transmission capacity will be five times higher than its current level. Policy choices will lead to different transition pathways as the early-stage installation decisions will have a lock-in effect on the following carbon emission reduction strategies and determine the importance of technologies adopted in achieving carbon neutrality. Although the transition to a low-carbon economy will result in an increase in cost by 17–19%, it will bring huge climate benefits to the world. [ABSTRACT FROM AUTHOR]

Carbon dioxide (CO2) Capture, Utilization and Storage (CCUS) is an indispensable part of the carbon removal technologies to achieve carbon neutrality for China. Our study focuses on China's CCUS pathways, and draws out three key conclusions: (1) in terms of the greenhouse gases emission reductions required to achieve carbon neutrality and based on current technology projections, the CO2 emission reductions to be achieved by CCUS are 0.6 ∼ 1.4 billion tonnes and 1 ∼ 1.8 billion tonnes in 2050 and 2060, respectively; (2) from the perspective of source-sink matching in China, the emission reduction potential provided by CCUS can basically meet the demand of carbon neutrality target (0.6 ∼ 2.1 billion tonnes of CO2); (3) with the development of technologies, the cost of CCUS in China has a great potential to be reduced in the future. It is expected that by 2030, the technical cost of the whole CCUS process (according to 250 kilometers transportation) in China will be 310 ∼ 770 Chinese Yuan per tonne of CO2, and by 2060, it will gradually drop to 140 ∼ 410 Chinese Yuan per tonne of CO2.

Promoting energy transformation is a major issue in achieving China's carbon neutrality target. The changes in China's energy consumption stemming from the policies related to this issue were simulated based on the energy policy simulation model. The results show the following. (1) Implementing related policies will significantly decrease total primary energy consumption, and non-fossil energy will be China's main source of energy consumption by 2050. (2) The energy consumption corresponding to buildings, transportation, and industry will be electricity-led by 2050, and electricity will mainly be generated with non-fossil energy sources. (3) In 2030, China will reach a carbon peak, and non-fossil energy will account for 43% of the country's primary energy consumption, comprising electrical (73%), solar (11%), wind (7%), hydro (7%) and biomass (2%) energy. (4) COVID-19 has had a short-term driving effect on this process, as it initially slowed down global economic cooperation, but it has had a hindering effect on the process in the long term.
