基于健康的推动环境空气质量标准修订环境空气质量标准制修订方法及在上海实践-115页_5mb

The report analyzes the development of China's environmental air quality standards and proposes methods for their revision based on health impacts, with a focus on Shanghai. Key findings include:

• China's current standards (GB3095-2012) are rooted in WHO guidelines and require updating using domestic evidence.
• Since 2013, China's air quality has improved significantly, but current standards are still insufficient from a health perspective.
• Shanghai's PM2.5 levels are among the best in China, but stricter local standards are recommended for better public health protection.
• Expert interviews confirm the need for standard revisions and Shanghai introduces more stringent regional standards.

The report emphasizes that health-oriented standards are essential for advancing China's air quality management while balancing environmental health and economic development.

Key Recommendations:

• Shorten National Standards: Update PM2.5 limits to better align with health evidence while considering economic feasibility.
• Implement Stricter Local Standards: Shanghai proposes tighter limits (e.g., annual PM2.5 < 25μg/m³ or even more stringent values) than national standards.
• Align air quality management with China’s goals for sustainability while ensuring scientific rigor and public health benefits.

This research supports policy decisions that promote cleaner air and healthier populations through evidence-based standards revision.
