Core Viewpoint - The Ministry of Ecology and Environment, in collaboration with the National Development and Reform Commission and the Ministry of Industry and Information Technology, has issued the "Nitrous Oxide Emission Control Action Plan" for the industrial sector, setting the tone and direction for future nitrous oxide emission control efforts in China, which will positively impact the green and low-carbon transformation of the industry [1][2]. Group 1: Emission Control and Impact - Nitrous oxide is the third-largest greenhouse gas globally, with a global warming potential approximately 300 times that of carbon dioxide, and its atmospheric lifespan exceeds 100 years [1]. - In 2021, China's nitrous oxide emissions accounted for about 4.3% of the total greenhouse gas emissions, with industrial nitrous oxide emissions estimated at 154 million tons of CO2 equivalent [1]. - The main sources of nitrous oxide emissions in the industrial sector are the production processes of adipic acid, nitric acid, and caprolactam, with the adipic acid industry being the largest contributor [2]. Group 2: Policy and Technological Development - The action plan aims to enhance emission reduction technology innovation and management capabilities, improve the control and recycling levels of nitrous oxide emissions in the industrial sector, and promote continuous reductions in nitrous oxide emissions per unit product in the adipic acid, nitric acid, and caprolactam industries [2]. - Effective control of nitrous oxide emissions in the industrial sector can provide climate benefits by mitigating global warming, environmental benefits by controlling pollutants, and economic benefits through resource utilization, supporting the integrated approach of "carbon reduction, pollution reduction, and green growth" [2]. - Since 2021, China has gradually included nitrous oxide emission data from nitric acid production in the national carbon market, and domestic companies have developed proprietary emission reduction technologies with competitive efficiency and cost advantages [3].

Core Viewpoint - The article discusses the implementation of the "Nitrous Oxide Emission Control Action Plan" in the industrial sector, aiming to enhance the recovery and control of nitrous oxide emissions, thereby promoting a green and low-carbon industrial transformation by 2030 [3][4]. Summary by Sections Nitrous Oxide Emissions in Industry - Nitrous oxide (N2O) is the third-largest greenhouse gas after carbon dioxide and methane, with a global warming potential approximately 300 times that of CO2. In 2021, China's total nitrous oxide emissions were 2.102 million tons, accounting for 4.3% of total greenhouse gas emissions, with industrial processes contributing 580,000 tons, or 27.6% [3][4]. Key Industries and Emission Sources - The primary sources of nitrous oxide emissions in the industrial sector are the production processes of adipic acid, nitric acid, and caprolactam, with adipic acid being the largest contributor. China's production capacity for these chemicals exceeds 50% of the global total, and this capacity is expected to continue growing [4][6]. Emission Reduction Potential - The "Global Nitrous Oxide Assessment" report by the United Nations Environment Programme indicates that achieving high scenario reductions globally could lead to a potential reduction of 115 million tons of CO2 equivalent emissions annually from the industrial sector alone [4][6]. Benefits of Emission Control - Effective control of nitrous oxide emissions can provide climate benefits by mitigating global warming, environmental benefits through the reduction of other pollutants, and economic benefits via resource recovery. This initiative is expected to encourage companies to innovate production processes and enhance resource efficiency [6][7]. Support and Funding Mechanisms - The action plan suggests utilizing funding channels to support the construction of nitrous oxide recovery and purification facilities, as well as emission reduction devices in key industries. It encourages climate financing and the inclusion of projects with nitrous oxide reduction benefits in ecological and climate financing support programs [7][8]. Technological Innovation and Collaboration - Continuous research and development of key technologies for source and process control, resource utilization, and monitoring are emphasized. The establishment of a reporting system for nitrous oxide emissions from key enterprises and the exploration of automatic monitoring systems are also recommended [7][8]. Strategic Goals - The initiative aims to transition from end-of-pipe treatment to lifecycle management of nitrous oxide emissions, aligning with the goals of the United Nations Framework Convention on Climate Change and promoting green development under the Belt and Road Initiative [7][8].

Core Viewpoint - The Chinese government is implementing a comprehensive action plan to control nitrous oxide (N2O) emissions in the industrial sector, aiming for significant reductions and technological advancements by 2030 [1][2]. Group 1: Policy and Action Plan - The "Action Plan" aims to enhance N2O emission control policies, improve reduction technology innovation capabilities, and strengthen emission management in the industrial sector by 2030 [1][4]. - The plan specifically targets the adipic acid, nitric acid, and caprolactam industries, which are the primary sources of industrial N2O emissions [2][4]. - By 2021, China's total N2O emissions were 2.102 million tons, accounting for 4.3% of total greenhouse gas emissions, with industrial production contributing 580,000 tons [1]. Group 2: Industry Focus and Potential - The adipic acid, nitric acid, and caprolactam industries account for over 50% of global production capacity, with expected growth in capacity [2]. - The potential for N2O reduction in the industrial sector is estimated at 115 million tons of CO2 equivalent annually if high scenario reductions are achieved globally [2]. Group 3: Environmental and Economic Benefits - Controlling N2O emissions not only mitigates climate change but also offers environmental benefits by reducing other pollutants and economic benefits through resource recovery [4][5]. - The plan encourages investment in N2O recovery and reduction technologies, promoting projects with N2O reduction benefits to be included in financial support programs [4][5]. Group 4: Technological Innovation and Collaboration - Continuous research and development of key technologies for source control, resource utilization, and monitoring are emphasized [5]. - The establishment of a reporting system for N2O emissions from key enterprises and the development of monitoring standards are part of the strategy [5].
