This paper applies an emission factor approach to measuring the PM 2.5 (particulate matter suspended in the atmosphere with diameter ≤ 2.5 μm) emissions from industrial sources in Chengdu. The results show that the PM 2.5 emissions from industrial sources are 12,264.14 tons in 2013, of that, 3257.76 tons, or 26.56% of the total, are from stationary combustion source. Industrial processes accounts for the remaining 9006.38 tons, or 73.44% of PM 2.5 emissions. The Districts of Qing Baijiang, Pengzhou, Jintang, and Du Jiangyan are the principal areas to contribute industrial emissions in Chengdu, whilst the corresponding industries are cement, steel, fertilizer, and coal-fired electricity. The study is expected to provide insight into the emissions reduction, and the improvement of air quality in Chengdu. Limitations of the assessment are addressed to lay out a foundation for further study.
