Quantifying Air Pollutant Emission from Agricultural Machinery Using Surveys—A Case Study in Anhui, China

Diesel-powered agricultural machinery (AM) is a significant contributor to air pollutant emissions, including nitrogen oxides (NOx) and particulate matter (PM). However, the fuel consumption emissions from AM remain poorly quantified in many countries due lack of accurate activity data factors. In this study, emission were estimated using survey factors literature. A case study was conducted collected Anhui, one provinces China. The annual active hours Anhui ranged 130 175 h. diesel by 1.45 Tg 2013, approximately 25% total province. pollutants emitted 57 Gg carbon monoxide, 14 hydrocarbon, 74 NOx 5.7 PM 2013. equivalent 17% 22% on-road traffic Anhui. Among nine types considered, rural vehicles are largest contributors (31%) (33–45%).
