迈向“十五五” 报告勾勒减污降碳协同战略新蓝图

Core Viewpoint - The report emphasizes the importance of assessing the progress and challenges of carbon neutrality and clean air in China, which is essential for fulfilling international commitments and promoting high-quality domestic development [1] Air Pollution and Climate Change - Ozone (O3) concentration is showing a fluctuating upward trend, with VOCs reduction efforts being insufficient and global warming contributing to increased heatwave days, which are potential reasons for inadequate ozone pollution control [2] - The PM2.5 pollution in 2020 was most severe in cities concentrated in the Beijing-Tianjin-Hebei region and surrounding areas, with a projected overall concentration decrease to 50μg/m³ by 2024 [2] - The distribution of O3 pollution has changed, with new pollution centers emerging in eastern Hubei province, and the overall situation worsening in 2024, particularly in the Beijing-Tianjin-Hebei region and Fenwei Plain [2] Governance System and Practices - China is gradually establishing a multi-departmental collaborative governance system that includes administrative, economic, and social governance methods, although challenges remain, particularly in high carbon emission cities where PM2.5 pollution is more severe [3] Structural Transformation and Governance Technology - The trend in fossil energy consumption is diverging, with a slowdown in coal consumption growth and a decrease in coal power approvals since the 14th Five-Year Plan began, although chemical industry output growth remains a major factor for industrial coal consumption [4] - Advanced manufacturing and digital industries are driving rapid growth in electricity demand, while carbon capture, utilization, and storage (CCUS) technologies are developing quickly, with significant milestones achieved in various aspects [4] Atmospheric Composition Sources and Reduction Pathways - From 2020 to 2024, human-induced carbon dioxide emissions increased by 15.4%, posing significant pressure on achieving the carbon reduction targets of the 14th Five-Year Plan, with a cumulative carbon intensity reduction of approximately 7.8% by 2024 compared to 2020 [5] - The stability of terrestrial carbon sinks has been maintained during the 14th Five-Year Plan, but the annual growth rate has slowed, necessitating scientific forest management to sustain carbon sink growth [5] Health Impacts and Synergistic Benefits - The number of deaths attributed to PM2.5 exposure is decreasing, but there has been no significant improvement in deaths related to ozone pollution, with extreme weather events from climate change severely impacting public health [6] - Collaborative governance is expected to yield significant health benefits, requiring further efforts in areas such as integrating clean energy use, building energy efficiency, and improving indoor air quality into pollution reduction policies [6]
