空气质量标准修订符合中国国情（答问九）

Group 1 - The revised air quality standards in China still lag behind those of developed countries like the US and EU, indicating a need for standards that reflect national conditions rather than simply adopting the strictest international levels [1] - The US EPA plans to tighten the PM2.5 annual average from 12 micrograms per cubic meter to 9 micrograms per cubic meter by 2024, while China's secondary limit remains relatively lenient [1] - The revision of standards should consider factors such as spatial layout, industrial structure, resource endowment, environmental capacity, and governance capabilities to ensure they are scientific, reasonable, and achievable [1] Group 2 - China's reliance on coal as a primary energy source is expected to persist in the short term, contributing to higher emissions of air pollutants due to its status as a manufacturing powerhouse, accounting for nearly 30% of global manufacturing value added [2] - By 2035, China is projected to reach a level comparable to that of middle-income developed countries, where PM2.5 limits are around 25 micrograms per cubic meter, aligning with the country's current economic and social development stage [2] - The standard revision reflects China's confidence and determination to lead continuous improvements in environmental quality, supporting the goal of building a beautiful China and better protecting public health [2]
