Estimation of NOx Emission from Fossil Fuel Consumption in China for the Period 1980-2012

Abstract

As the largest consumer of fossil fuel, China NOx emission from energy consumption has become a hotspot for studies. In this study, emission inventory was used to analysis the historical variation of NOx emission in china for the period 1980 to 2012. Results indicate that NOx mission of China has increased from 446.45 × 104t to 2499.72 × 104t during 1980-2012, electricity, industry and transportation was the main contributor and NOx emission has increased from 145.04 × 104t, 206.75 × 104t, 39.44 × 104t to 1311.6 × 104t, 479.46 × 104t, 576.31 × 104t respectively; from the spatial pattern, high total NOx emission with mainly concentrated in the north of China and the high emission intensity mainly concentrate in eastern China.
