Further works Engineering machinery, agricultural machinery, marine emission factor test are lack of test data of different power section. Currently, there no program for coastal vessel emission test. We need to constantly carry out non-road machinery emission test, and improve emission factor database. Considering the policy requirements for evaluating non-road mobile source GHG and PM2.5 emission effect, we should utilize existing data to supplement CO2 and PM2.5 emissions factor. We should establish contextual models for different emission standards, carry out emission inventory forecast, and provide policy suggestions for non-road mobile source emission control. 谢谢聆听!
