The Ministry of Ecology and Environment and three other departments have issued the Action Plan for Controlling Nitrous Oxide Emissions in the Industrial Sector, which clarifies that by 2030, the policies for controlling nitrous oxide emissions in the industrial sector will be further improved, the innovation capability for emission reduction technology will be significantly enhanced, the emission management capability will be significantly strengthened, and the level of nitrous oxide recovery, utilization, and emission control will be effectively improved.

The Action Plan for Controlling Nitrous Oxide Emissions in the Industrial Sector has been released

Nitrous oxide (N ₂ O) is the third largest greenhouse gas after carbon dioxide and methane, and is an important non carbon dioxide greenhouse gas. Its warming potential is about 300 times that of carbon dioxide, and its chemical properties are relatively stable. Its atmospheric lifespan is over a hundred years. Adipic acid, nitric acid, and caprolactam industries in the industrial sector are one of the main sources of nitrous oxide emissions. Due to their relatively concentrated emission sources, clear emission reduction technology routes, and lower emission control costs, they have received more widespread attention.

Recently, the Ministry of Ecology and Environment, together with the National Development and Reform Commission and the Ministry of Industry and Information Technology, issued the "Action Plan for Controlling Nitrous Oxide Emissions in the Industrial Sector" (hereinafter referred to as the "Plan"). The Plan specifies that by 2030, policies for controlling nitrous oxide emissions in the industrial sector will be further improved, innovative emission reduction technologies will be significantly enhanced, emission management capabilities will be significantly strengthened, and the level of nitrous oxide recovery, utilization, and emission control will be effectively improved. The emissions of nitrous oxide per unit product in the adipic acid industry, nitric acid industry, and caprolactam industry have continued to decline, reaching the international leading level. Subsequently, efforts will be gradually strengthened to control nitrous oxide in the industrial sector.
