Can Beijing, Tianjin and Hebei Achieve Their PM2.5 Targets by 2017?Post date: 2014-12-02

Introduction: China's State Council has set new PM2.5 improvement targets for Beijing-Tianjin-Hebei area in the new Air Pollution Prevention and Control Action Plan. In this study, we combined Beijing-Tianjin-Hebei regional emission inventories and Community Multi- Scale Air Quality (CMAQ) modeling to evaluate the air quality improvement effect in the region under the measures proposed in the local air pollution action plans for the period from 2012-2017. Our modeling results indicated that significant improvements of air quality in the Beijing-Tianjin-Heibei region can be achieved in 2017 if the local action plans are fully implemented, but there are risks that they might fail to achieve the PM2.5 target (Beijing : 60μg/ m3 , Tianjin and Hebei : 25% decline) from the Action Plan. Our report also recommends ten enhanced measures to ensure the Beijing-Tianjin-Heibei region can achieve the PM2.5 improvement targets set by the central government.
