中国多举措加强工业领域氧化亚氮控排工作

Core Viewpoint - China is taking multiple measures to strengthen the control and reduction of nitrous oxide emissions in the industrial sector, emphasizing the establishment of a collaborative alliance to innovate and standardize monitoring and reduction technologies [1][2] Group 1: Nitrous Oxide Emissions Overview - Nitrous oxide is the third-largest greenhouse gas globally, with a global warming potential approximately 300 times that of carbon dioxide, and it has a stable chemical nature with an atmospheric lifespan exceeding 100 years [1] - In 2021, China's total nitrous oxide emissions were 2.102 million tons, accounting for 4.3% of the country's total greenhouse gas emissions, with industrial processes contributing 580,000 tons, or 27.6% of the total [1] Group 2: Industrial Sources and Reduction Goals - The primary sources of nitrous oxide emissions in China's industrial sector are the production processes of adipic acid, nitric acid, and caprolactam, with the adipic acid industry being the largest contributor [1] - The establishment of the alliance is seen as a crucial step towards achieving China's dual carbon goals, promoting deep integration of production, learning, research, and application to build a green and low-carbon industrial system [1] Group 3: Future Plans and Initiatives - The "Action Plan for Controlling Nitrous Oxide Emissions in the Industrial Sector" aims to improve emission control policies, enhance innovation capabilities for reduction technologies, and strengthen management capabilities by 2030 [2] - The alliance, initiated by the National Center for Climate Change Strategy and International Cooperation and the China Chemical Energy Conservation Technology Association, will accelerate the development of monitoring standards and encourage market mechanisms for emissions reduction [2]
