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.

China’s marine environment has enormous volumes of oil and gas (O＆G) resources and immense “blue carbon” potential. In the 14th Five-Year Plan, developing the marine economy, using marine resources, and protecting the marine ecological environment are one of China’s important socioeconomic development goals. However, the relationship between the exploitation of offshore O＆G resources, the protection of the marine ecosystem, and the goal of carbon peak and carbon neutrality has not been fully elucidated. This study expounds on the importance and vulnerability of marine ecosystems. Then it combines the status of offshore O＆G exploration and exploitation to present a conceptual model of offshore O＆G-ecology carbon feedback cycle, the pathway of deep connection, and the necessity of synergic development in carbon neutrality process. This paper advocates strategies such as closer combination of marine protection with offshore O＆G design and development, evaluating the carbon budget in the regional ecological assessment and developing low-carbon green oilfield materials to improve the sustainable development and utilization scheme of marine resources. This study aims to provide scientific and theoretical support for relevant institutions and promote in-depth collaboration across marine departments. [ABSTRACT FROM AUTHOR]

China has pledged to peak its carbon emissions before 2030 and achieve carbon neutrality before 2060. New energy decarbonization will be a major focus area for achieving the 'dual carbon' goals since it accounts for about 20 percent of China' s total energy consumption. The Xiong' an New Area' s geographical advantages and natural endowments have brought abundant wind and solar energy resources and have huge development potential in the field of new energy development. This paper summarizes the Xiong' an New Area' s resource endowment and achievements in developing new energy, and comprehensively analyzes the opportunities and challenges faced by this area in the process of building a national new energy demonstration zone in the context of achieving the 'dual carbon' goals. It sorts out the new energy development policy of the Xiong' an New Area and its history of new energy development and then points out that the current development of new energy in this area lies in power project construction, power grid construction, green energy consumption, energy storage development, and new energy equipment. This study believes that the Xiong' an New Area will experience three development stages of carbon neutrality: initial carbon neutrality, fluctuating carbon neutrality, and stable carbon neutrality, because this area has carried out green power planning simultaneously in the initial construction stage and has more green power supply. With the expansion of population and economic scale, the rapid increase in energy demand would lead to the decline in green power supply ratio, causing carbon neutrality to fluctuate and change over time. With the population and economic structure in a stable development stage, the proportion of high-value-added and high-tech industries would increase, and energy utilization technologies such as green electricity would make progress, resulting in the arrival of the stable carbon neutrality development stage. On the other hand, from the perspective of carbon sink potential corresponding to carbon sources, the planned proportion of the blue-green space and the construction land in the Xiong' an New Area would keep its carbon sink capacity in a relatively stable state for a long period of time. Therefore, in addition to the value-added of the natural carbon sink system, carbon capture, utilization and storage technologies and other means of artificial carbon sink can be used as adjustment tools under the carbon neutrality system.

As the world' s largest energy consumer and carbon emitter, China faces a serious situation in energy conservation and emission reduction. However, China' s digital economy is still developing rapidly. In order to explore how the development of the digital economy affects energy consumption and CO2 emissions, this paper took the panel data of 30 provinces in China from 2011 to 2019 as a sample, used the entropy method to analyze the digital economy level of each province, and built a double fixed effect model to empirically analyze the 'positive U-shaped' or 'inverted U-shaped' relationship between the digital economy and energy or between the digital economy and CO2 emissions. The results showed that: (1) There were inter-provincial and regional differences in the level of digital economy in China. Guangdong Province and China' s eastern region had the highest level of digital economy, while Qinghai Province and the western region had the lowest level of digital economy. (2) Both the digital economy and ECSC and the digital economy and CESC had significant ' positive U-shaped' relationships, while the digital economy and ECST, the digital economy and ECEF, and the digital economy and CEEF all had significant 'inverted U-shaped' relationships. The energy-saving effect of the development of the digital economy was greater than the carbon emission reduction effect. (3) There was heterogeneity in the nonlinear relationship between the digital economy and ECSC, ECST, and ECEF, the digital economy and CESC, and CEEF in the eastern, central, western, and northeastern regions. (4) Digital infrastructure, digital innovation environment, digital user scale, and digital industry scale had different nonlinear effects on ECSC, ECST, and ECEF, as well as on CESC and CEEF. Accordingly, to provide empirical support and a theoretical basis for China's development of the digital economy while taking into account the effects of energy conservation and carbon emission reduction, this study puts forward relevant policy suggestions from three aspects: narrowing the gap in the level of digital economy, formulating digital economy development policies, and focusing on key points for the development of the digital economy. These suggestions are also conducive to boosting China's goals of reaching peak carbon emissions and achieving carbon neutrality. [ABSTRACT FROM AUTHOR]

Global warming is evolving into a crisis affecting the future of humanity. As the world' s second largest economy, China is actively involved in global climate governance, proposing to achieve the goals of reaching peak carbon emissions by 2030 and achieving carbon neutrality by 2060, and has successively introduced the corresponding ' 1+N' policy system. This paper attempts to interpret and analyze 23 policy texts relevant to the achievement of the goals with over 160 000 characters from the CPC Central Committee, the State Council, and relevant ministries and provinces through two typical qualitative research methods-ground theory and institutional grammar tool, to outline the elemental structure and functional profile of the pathways of China' s carbon peak and carbon neutrality policies, and to clarify the group structure and regulation intensity of different policy pathways. Based on grounded theory, it is found that these pathways are already very comprehensive and complete. Among them, the policy pathways under the administrative mechanism include: high energy consumption and high emission industrial control; regulations and standards systems; carbon reduction governance in key industries; control over the amount and intensity of energy consumption; and carbon absorption capacity of ecosystems. The policy pathways under the market mechanism include circular economy development; energy transformation development; cap-and-trade system for carbon emissions; green finance development; and green transformation development. The results of institutional grammar tool research show that relevant policy pathways are dominated by ADIC normative condition statements (177, accounting for 52%), followed by AIC strategy statements (130, accounting for 38%), while ADICO rule-based statements are the least, with only 33, accounting for 10%. Given the pressure of time constraints and heavy tasks to achieve the goals, ADICO' s institutional grammar structure is the most desirable policy statement paradigm because it is more intense in its policy regulation, and it is easier to achieve its governance effectiveness. Undoubtedly, policy regulation is an important tool to effectively alleviate the pressure of the governance of the goals and to ensure the effectiveness of such governance. Policy regulation mainly focuses on the industrial sector with high energy consumption and high emissions, relying on top-down hierarchical organization and using political mobilization and administrative decrees as means to promote governance in the high carbon emission sector. By further constructing a theoretical framework of regulation mechanisms, relevant governance paradigms are classified as ' mandatory governance' and ' flexible governance' according to the intensity of regulation. It is found that the underlying logic behind these two paradigms is precisely the mobilization of the administrative mechanism and the allocation of resources under the market mechanism. Simultaneously, with the gradual achievement of the goals and the gradual decoupling of carbon emissions from economic development, the governance logic should gradually shift from ' mandatory governance' to ' flexible governance,' and from ' administrative hierarchical mobilization' to ' balanced allocation of market resources.'

The goal of carbon neutrality and carbon peak requires major system changes in energy supply. As a clean low-carbon and stable non-carbon-based energy, geothermal energy can provide guarantee for the realization. The paper briefly introduces the occurrence conditions of geothermal resources in China, and summarizes the exploitation and utilization technology and development of shallow-middle deep geothermal energy and hydro-geothermal resources respectively in terms of direct utilization and geothermal power generation, focusing on the widely concerned new technology and direction such as geothermal refrigeration, gravity heat pipe and geothermal-solar power combined power generation and looking forward to the development and research direction to provide reference for related engineers and researchers.

In a speech at the UN General Assembly on September 22, 2020, President Xi Jinping announced that China would peak carbon dioxide emissions before 2030 and achieve carbon neutrality before 2060. China has issued a series of documents on the carbon peaking and neutrality goals, which have become hot issues in society. The concept of carbon peaking is relatively easy to understand, but for that of carbon neutrality, there are some misunderstandings, such as mixed use of different terms and ambiguous scope, classification, and relationships between related concepts, which not only directly affect the implementation of the 'dual carbon' goals in China, but also impede China􀆳s participation in global climate governance and international climate cooperation towards the goal of carbon neutrality. This paper attempts to trace the origin and evolution of the concept of carbon neutrality. It sorts out the different expressions of the carbon neutrality goal, compares the differences and correlations between related concepts, and discusses the key elements and implications of the concept of carbon neutrality. The discussion leads to the following conclusions: ① The concept of carbon neutrality was introduced to the field of global climate governance after carbon trading and carbon offsetting had been proposed in the Kyoto Protocol in 1997. ② The concept of carbon neutrality has both narrow and broad senses. Narrowly speaking, it refers to carbon dioxide neutrality, while in a broad sense, it is a collective term for related concepts such as carbon dioxide neutrality, greenhouse gas neutrality, climate neutrality, net zero carbon dioxide emissions, and net zero greenhouse gas emissions. In the international community, the expression 'net zero' is more widely used. ③ To understand the concept of carbon neutrality, four elements need to be grasped: the balance between the source and removal of anthropogenic emissions; multiple implementation entities and their carbon accounting boundaries; the scope of emissions (covering merely carbon dioxide or all greenhouse gases); and carbon neutralization paths including carbon emission reduction, carbon removal, carbon offsets, etc. ④ Clarifying the concept of carbon neutrality is the basis for efficiently implementing the 'dual carbon' goals and promoting international cooperation. The terms used in the legal documents and IPCC guidelines and reports approved in the UNFCCC negotiations are internationally accepted concepts and norms. They are recognized by various governments and serve as an important foundation for scientific research as well as the cognitive basis for international negotiations and actions. The definition and interpretation of the concept of carbon neutrality should be consistent with the international community as much as possible to form a unified understanding that is not only conducive to promoting international cooperation towards carbon neutrality, but also to China' s implementation of the Paris Agreement and advancement of work towards the 'dual carbon' goals.
