Vehicle emissions have become one of the most important air pollution sources in China. Promoting vehicle synergistic reduction of pollution and carbon is the key to improving regional environmental quality and achieving the carbon peaking and carbon neutrality goals. Building a collaborative evaluation system and comprehensive quantitative method is an important prerequisite for scientific and effective implementation of vehicle pollution and carbon synergistic reduction. Therefore, it is significant to extensively review existing synergistic evaluation methods and comprehensive environmental benefit accounting methods of atmospheric pollution and carbon reduction. On this basis, we focused on vehicle emission characteristics, systematically organized the key indicators of vehicle collaborative reduction evaluation, and summarized quantitative methods of policy effects from three aspects (health exposure cost, climate change cost, and pollutant control cost), to provide theoretical support for policy formulation, schemes selection, and their effect evaluation. For the future, the assessment of vehicle coordinated emission reduction is proposed to accelerate unified index system establishment, deeply analyze the spatial distribution of environmental benefits, focus on the pollution transfer caused by vehicle electrification, and explore the quantitative methods of climate change cost due to extreme weather.
