| Based on scenario analysis, the vehicle emissions of normal pollutants in Quanzhou in 2020 were estimated in five setting scenarios, the reduction ratio of total vehicle emissions and various vehicles emissions were discussed. The results showed that vehicle emissions would increase significantly in 2020 compared to 2015,the total emission would be 1.098×105 tons, the growth rate of each pollutant emissions were in the range of 6.5%~13.7%. Different control measures had good efforts on emission reduction, among which cleaning out “yellow label cars” was the most effective, next was “buses have priority” which could effectively reduce the activity level of vehicles, then was “tightened emissions standards”, new energy vehicles contributed the least emissions and had great potentiality of reduction. When all the measures were comprehensively implemented, the reduction effect was the most significant. |
