Abstract In this paper, particulate matter (PM) and nitrogen oxide (NOx) emissions of agricultural machinery in Tianjin were estimated based on fleet make-up and fuel consumption from a survey questionnaire. In 2010, total count of agricultural machinery in Tianjin was approximately 575000, 52.5% being planting machinery. The total power of all agricultural machinery was approximately 5.88 million kilowatts, while transport machinery had the greatest share of 47.3%. Total fuel consumption of agricultural machinery in Tianjin was estimated as 67000 t; over-half of it was by transport machinery (45000t). The annual PM and NOx emission estimates from agricultural machinery in Tianjin were 303and 3470tons, respectively.
