From Fog to Smog: The Value of Pollution Information
研究2013年中国空气质量监测与数据公开项目,发现信息公开促使公众减少户外暴露、增加防护消费,从而降低死亡率,健康收益远超成本。
In 2013, China launched a landmark program to monitor air quality and disclose real-time data, significantly increasing the public’s access to and awareness of pollution information. The program triggered cascading behavioral changes such as stronger avoidance of outdoor pollution exposure and increased spending on protective products. These behavioral responses mitigated the mortality impact of air pollution. Conservative estimates indicate that the program’s health benefits outweigh the costs by an order of magnitude. The findings highlight the benefits of improving public access to pollution information in developing countries which often experience severe air pollution but lack pollution data collection and dissemination.
