With the advancement of urbanization，the number of motor vehicles in China is increasing，becoming the fastest growing area of greenhouse gas emissions，and the total emissions account for about 15% of the national terminal carbon emissions. Promoting low-carbon certification in the transportation industry and developing green transportation are important for achieving the goal of “double carbon target”. In this report，the current situation and characteristics of carbon emissions and low-carbon certification in the transportation industry are expounded clearly，and the carbon footprint accounting methods of different modes of transportation and the problems in low-carbon certification are analyzed in detail. Finally，combined with the experience of carbon label development at home and abroad，suggestions and prospects for the development of low-carbon certification in the transportation industry are put forward.
