Core Points - The Chinese government has announced a new round of national contributions to reduce greenhouse gas emissions, aiming for a 7%-10% decrease in total emissions by 2035 compared to peak levels, marking a significant milestone in climate change response [1] - The focus on controlling non-CO2 greenhouse gases has been integrated into China's carbon peak and carbon neutrality policy framework since the announcement of the "dual carbon" goals in 2020 [2] Group 1: National Policy and Goals - The new absolute reduction target for greenhouse gases includes all types of emissions, emphasizing the importance of controlling non-CO2 gases such as methane and nitrous oxide [1][2] - The government has issued various policies to strengthen the control of non-CO2 gases, including action plans for methane emissions and guidelines for greenhouse gas inventory compilation [3][4] Group 2: Implementation Strategies - A series of supporting policies have been developed, such as revising emission standards and implementing action plans for specific sectors like agriculture and industry to reduce greenhouse gas emissions [3][4] - The establishment of a carbon market that includes non-CO2 gases and the development of a national greenhouse gas emission factor database are part of the efforts to enhance emission control mechanisms [4] Group 3: Local Level Challenges and Recommendations - Local governments face challenges such as unclear emission data and inadequate policy frameworks for controlling non-CO2 gases [5] - Recommendations include improving data collection, developing localized policies, and implementing targeted emission control measures based on regional characteristics [5][6]
