中国科学院院士朱彤：尽快修订环境空气质量标准 以健康驱动空气质量持续改善

Core Viewpoint - The article emphasizes the urgent need for China to revise its air quality standards, particularly for PM2.5, to maximize health benefits and promote sustainable development in the context of air pollution and climate change [1][3][5]. Group 1: Air Quality Standards and Health - The current air quality standards, established in 2012, are no longer effective for many cities that have met the existing PM2.5 limits, necessitating a revision to provide long-term goals for continuous air quality improvement [4][7]. - The latest data indicates that in 2024, the national average PM2.5 concentration is 29.3 micrograms per cubic meter, with 252 cities meeting the PM2.5 annual average standard [3][4]. - The World Health Organization (WHO) has set a new guideline for PM2.5 at 5 micrograms per cubic meter, which has sparked discussions on how to balance international standards with China's specific conditions [5][6]. Group 2: Collaborative Governance - The article advocates for a collaborative governance approach to address air pollution and climate change, highlighting the interconnectedness of these issues due to human activities [8][9]. - It suggests that health protection should be a primary goal in formulating strategies for air pollution control and climate change mitigation, promoting coordinated efforts to reduce both air pollutants and greenhouse gases [9][10]. Group 3: Green Technology and Corporate Responsibility - Companies are encouraged to invest in green technologies, such as electric vehicles and clean heating solutions, to contribute to air quality improvement and carbon reduction [10][11]. - The article stresses the importance of businesses aligning with national pollution reduction goals and adopting sustainable practices to ensure long-term viability and societal responsibility [12][13]. Group 4: International Cooperation - China is positioned to share its experiences and technologies in air pollution control with other developing countries facing similar challenges, enhancing its role in global environmental governance [13][14]. - The article highlights the potential for Chinese scientists to influence international discussions and collaborations on air quality and climate change, promoting a unified approach to these global issues [14].
