【摘要】 2022年10月，中国发布了《第四次气候变化国家评估报告》，其中减缓气候变化部分首先阐述了国际气候治理新机制给中国带来的挑战和机遇、中国现阶段碳减排成效以及经济转型对碳减排的影响，然后对能源部门碳减排、能源需求部门（工业、建筑、交通）碳减排、碳汇和非二氧化碳减排、CCUS和地球工程进行了评估，最后分析了2030年前二氧化碳排放达峰路径和2060年碳中和目标愿景。这些评估分析结论为中国更好地开展碳达峰、碳中和工作提供了重要支撑。更多还原

【Abstract】 In October 2022, China released the Fourth National Assessment Report on Climate Change. The third part, which is on climate change mitigation, describes China’s challenges and opportunities, carbon emissions reduction progress, and the impact of China’s socioeconomic transformation on emission reduction. It then assesses carbon emission reductions in energy supply and demand sectors(industry, construction, and transportation), carbon sinks and non-CO2 greenhouse gas emission reduction, as well as CCUS and geo-engineering technologies. Finally, it analyzes the pathways to reaching peak carbon emissions by 2030 and achieving carbon neutrality by 2060. It is hoped that the conclusions of the assessment will provide an important scientific reference for China’s sustainable development toward reaching peak carbon emissions and achieving carbon neutrality.更多还原
