China has emerged as a global leader in addressing nitrous oxide (N2O) emissions, showcasing a successful blend of pollution control and climate action. Since 2013, the country has managed to stabilize and subsequently reduce the growth rate of anthropogenic N2O emissions, a greenhouse gas significantly more potent than carbon dioxide. This achievement underscores that economic growth does not inevitably lead to increased emissions of heat-trapping gases. Han Yinghui, an associate professor at the University of Chinese Academy of Sciences, emphasized the critical role of N2O in achieving global temperature goals during a recent event at the Chinese pavilion at COP30 in Belem, Brazil. N2O, with a global warming potential nearly 300 times that of CO2, remains in the atmosphere for over a century, making its control essential for mitigating severe climate impacts. While agriculture is the largest source of N2O emissions globally, industrial sources present the greatest potential for reduction. Han highlighted that while developed countries have historically contributed the most to cumulative N2O emissions, recent increases have been driven by emerging economies in Asia, necessitating global cooperation. China’s progress in N2O control is attributed to ‘synergistic governance,’ integrating climate goals into environmental management. The country has widely adopted selective catalytic reduction (SCR) technology in coal-fired power plants, achieving a 70 to 90 percent reduction in N2O emissions. Additionally, China has introduced an action plan targeting industrial N2O emissions and is incorporating N2O data into its national carbon trading system. Proven technologies, such as exhaust gas purification in adipic acid production, are already in use, removing over 95 percent of N2O emissions while recovering the gas as a useful industrial product. China’s validated industrial technologies are scalable and ready for global sharing, helping other nations avoid carbon-intensive development pathways.
