Abstract:Nitrogen oxides (NOx) from vehicle, as one of the main sources of NOx in atmosphere, have a significant effect on urban air quality. Vehicular NOx emission inventory of Hangzhou was established in 2010 and the increased emission of vehicular NOx during 12th Five-Year Plan was also predicted. Then NOx emission reduction potential was analyzed under three scenarios: the current management, improvement scheme and strengthening scheme. The results showed that vehicular NOx emission of Hangzhou was 44300t mainly from heavy trucks which contributed to 34.1%. Vehicle population will increase 22000 with 1960t NOx emission increment in 2015. Scenario analysis revealed that improvement scheme including eliminating old vehicles and using better oil could reduce NOx emission 7460t with a reduction rate of 16.84%. And hybrid vehicle usage and alternative energy replacement will reduce NOx emissions greatly.
