环境空气质量标准修订对经济高质量发展发挥积极作用（答问八）

Core Viewpoint - The recent revision of the air quality standards by the Ministry of Ecology and Environment aims to tighten the concentration limits for pollutants such as PM2.5, PM10, SO2, and NO2, which is expected to positively impact economic development and public health despite concerns about potential negative effects on economic growth [1][2]. Group 1: Impact on Air Quality and Economy - The revision of air quality standards has historically led to significant improvements in air quality, with a 36% decrease in average PM2.5 concentration and a 68% reduction in heavy pollution days over the past decade, while GDP increased by 63% and vehicle ownership rose by 111% [1]. - The implementation of stricter air quality standards has facilitated a strategic shift in pollution control, moving from total emissions control to a focus on air quality improvement, and from single pollutant management to multi-pollutant coordination [1][2]. Group 2: Implementation and Long-term Benefits - The revised standards will be implemented in phases to minimize the impact on economic and social stability, allowing for a gradual transition to meet the new requirements [2]. - Long-term benefits of stricter standards include further reductions in PM2.5 levels, improved public health outcomes by decreasing the incidence of cardiovascular and respiratory diseases, and the promotion of green technologies in industries such as new energy vehicles and clean energy [2].
