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 …

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 …

Scientific And Technological Reasons, Contents And Corresponding Policies Of Constructing “Coastal Grass Belt”, Weihua Xu, Jianlin Wang, Xiaojing Liu, Qi Xie, Weicai Yang, Xiaofeng Cao, Zhensheng Li
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 …
