Build New Power System To Promote Carbon Neutrality, Li Kong, Wei Pei, Jianye Rao, Yingxin Xu
Bulletin of Chinese Academy of Sciences (Chinese Version)
Under the 'carbon peak and carbon neutrality' goal, the supply and demand of China's power system will continue to grow in the next 40 years. Firstly, this study comprehensively analyzes China's power grid system under the goal of carbon neutralization. In the future, wind power and solar power will gradually become the main power supply, which brings new tasks and challenges to the power grid to absorb the renewable energy. On this basis, the general idea and construction principles of building a new generation of power system are expounded. Then, the basic structure and form of the new generation of …

Alert To The Migration Of Air Pollution And Carbon Emission To Northwest China, Guiqian Tang, Yuting Liu, Wenkang Gao, Yinghong Wang, Tao Song, Mengtian Cheng, Yuesi Wang
Bulletin of Chinese Academy of Sciences (Chinese Version)
Air pollutants have strong homology with greenhouse gases and are closely related to fossil fuel combustion. The high-intensity energy use in the eastern region of China has turned this region into a hot area of carbon dioxide emission and heavy air pollution in the past. Since the implementation of the Action Plan for the Prevention and Control of Air Pollution, the adjustment of industrial structure and the improvement of terminal treatment technology have been driving the succession of key species of air pollution and the spatio-temporal distribution of greenhouse gases in China. This paper analyzes the trend in major air …

Green Consumption Under Carbon-Orientated: Connotation, Transmission Mechanism And Countermeasures, Hongchun Zhou, Zuoting Shi
Green Consumption Under Carbon-Orientated: Connotation, Transmission Mechanism And Countermeasures, Hongchun Zhou, Zuoting Shi
Bulletin of Chinese Academy of Sciences (Chinese Version)
As the proportion of consumption to GDP increases and its role in stimulating economic growth in China, the impact of residents' consumption has apparently become increased on resources, the environment and carbon dioxide emissions. Production is for consumption, and consumption in turn promotes production; consumption determines production and also guides the direction and development trend of production. Green consumption is not only a consumer's responsibility, but also higher requirements for producers:the entire process from raw material procurement, product production and transportation, product use, second product recycling, and final disposal must be low-carbon standards. It is very significant important to promote …

Perspective On Challenges In Accurately Estimating Remaining Carbon Budget For Climate Targets Of Paris Agreement, Tianjun Zhou, Xiaolong Chen
Perspective On Challenges In Accurately Estimating Remaining Carbon Budget For Climate Targets Of Paris Agreement, Tianjun Zhou, Xiaolong Chen
Bulletin of Chinese Academy of Sciences (Chinese Version)
In 2015, by signing up to the Paris Agreement on climate change, the United Nations Framework Convention on Climate Change (UNFCCC) parties pledged to keep global temperatures "well below" 2℃ above pre-industrial levels and to "pursue efforts to limit the temperature increase even further to 1.5℃". Limiting warming to 1.5℃/2℃ requires strictly limiting the total amount of carbon emissions between now and the end of the century. Global mean surface temperature has already witnessed a 1℃ more warming since the pre-industrial era and the cumulative anthropogenic CO2 emission has reached around 2 390 Gt CO2. An accurate estimation of the …

Bulletin of Chinese Academy of Sciences (Chinese Version)
Not only the grain rations must be secured absolutely in China, but also the feed grains. However, the limited arable land resource in China determines that grass planting shall not "compete for land with staple food". Planting high quality salt-tolerant forage grass on the saline wasteland and developing animal husbandry production can not only meet the demand of increasing proportion of animal protein in Chinese diet structure, but more importantly, it can help to solve the problems of insufficient forage planting and import over-dependence. Hence it plays an important role in guaranteeing national food security. Therefore, it is necessary to …

Review Of Eu’S Carbon Neutral Policy System And Its Enlightenment, Liping Dong, Jingjing Zeng, Jiansheng Qu, Huijuan Pei, Qin Liao, Yanfei Liu, Lina Liu, Bingxue Qin
Bulletin of Chinese Academy of Sciences (Chinese Version)
Carbon neutrality is a redefinition of human development mode, and a "self-reform" of the production paradigm. It not only affects the economic development of various countries, but also rebuilds the global geopolitical pattern. Since 2060 carbon neutrality target was proposed in September 2020, China has been working hard on exploring how to establish a system of the carbon neutral policy. By considering the system of carbon neutral policy in European Union that is relatively mature, this study comprehensively reviews and analyzes the EU's system of carbon neutral policy from policy framework, key industry measures, R&D deployment support, and fiscal and …

Co-Production Model As Another Strategy: Experience Of Japan In Dealing With Gap Problem In Welfare Service, Mai Shi, Siting Sha
Bulletin of Chinese Academy of Sciences (Chinese Version)
In recent years, when faced with the gap problem of welfare services, Japanese society has gradually realized that relying only on traditional problem-solving strategies could not meet all the needs of social life problems. Many practical innovations with "co-production" as the core were formed. Therefore, this study analyzes the causes of the gap problem in welfare services, clarifies the specific principle of "co-production" in problem solving, and on this basis refines it into a new strategy as "co-production model". By observing the functional mechanism of this new strategy in Japan's welfare service practice, this study holds that for the future …
