In this paper, we examine the effect of China's Natural Gas Transmission Project (NGTP) on air pollution. The NGTP is the pipeline network that connects to almost all provinces in China, providing clean energy for industry and households. We use satellite data to measure the country's air quality from 1999 to 2015 at the city level and manually collected information about when each city connected to a natural gas pipeline. We exploit variation in connection time, and use the predicted connection time of pipelines in each city as the instrument to address potential endogeneity concerns. We find that connecting to natural gas pipeline significantly reduces a city's air pollution by 8%.
