Current status and future projections of NOx emissions from energy related industries in China

Emission inventories of nitrogen oxides (NOx) in 2000 and 2005 were established based on the activity levels of China's energy related sectors and emission factors. Future emissions from 2010 to 2030 were projected under different scenarios of energy consumption and NOx emission control policies. The NOx emissions in 2000 and 2005 were 12.1 × 106 t and 19.1 × 106 t, respectively. By 2030, the emissions would increase to 35.4 × 106 t under the reference scenario and would probably fall to 24.6 × 106-20.4 × 106 t under policy scenarios.
