空气质量标准调后与发达国家仍有差距？生态环境部：不能照抄

Core Viewpoint - The Ministry of Ecology and Environment emphasizes the need to develop air quality standards that consider national conditions while protecting public health, rather than simply adopting international standards [1][2] Group 1: Air Quality Standards - The Ministry of Ecology and Environment is revising PM2.5 concentration limits, taking into account the country's specific circumstances and development stage [1] - The U.S. Environmental Protection Agency 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 revised standards will 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: National Context - China's energy structure, primarily reliant on coal, is expected to change slowly, and as a major manufacturing country, it contributes significantly to air pollution emissions [1] - By 2035, China is projected to reach the level of a moderately developed country, with PM2.5 limits in developed countries at similar economic stages around 25 micrograms per cubic meter [1] - The standard revision reflects China's confidence and determination to lead continuous improvements in environmental quality, supporting the goal of building a beautiful China [2]
