Can promoting ethanol gasoline usage improve air quality? Evidence from Tianjin, China
Promoting the use of ethanol gasoline is an important approach for China to achieve sustainable and high-quality development. Based on the daily air quality data of Tianjin, China, from 2013 to 2020, this paper investigates whether the implementation of the ethanol gasoline policy helped improve air quality using regression discontinuity analysis. We find that the implementation of the ethanol gasoline policy had a very limited positive effect on the overall air quality index (AQI) and no obvious effect on the reduction of particulate matter (PM2.5 and PM10). However, the results reveal that the ethanol gasoline policy reduced SO2, NO2, and CO by about 36%, 19%, and 20%, respectively. These findings provide policy insights for other cities in China and other rapidly developing cities in the world to promote the use of ethanol gasoline.
期刊介绍：
The Chinese Journal of Population, Resources and Environment (CJPRE) is a peer-reviewed international academic journal that publishes original research in the fields of economic, population, resource, and environment studies as they relate to sustainable development. The journal aims to address and evaluate theoretical frameworks, capability building initiatives, strategic goals, ethical values, empirical research, methodologies, and techniques in the field. CJPRE began publication in 1992 and is sponsored by the Chinese Society for Sustainable Development (CSSD), the Research Center for Sustainable Development of Shandong Province, the Administrative Center for China's Agenda 21 (ACCA21), and Shandong Normal University. The Chinese title of the journal was inscribed by the former Chinese leader, Mr. Deng Xiaoping. Initially focused on China's advances in sustainable development, CJPRE now also highlights global developments from both developed and developing countries.
