Carbon emission is an inevitable outcome of the initial stage of economic development,especially the right of developing countries existence and development.The carbon emissions of China have been maintained at a low level for a long time and became the top of the world in 2005.However,per capita carbon emission was still only 46.28% of the United States in 2016.China's total CO₂ emissions are expected to reach 17~19Gt per y by 2030.To achieve the goal of carbon neutrality in 2060,it's necessary to change the energy structure, improve emission reduction technology and make the energy structure more reasonable.Therefore,replacing coal with gas is one of the most effective ways of emission reduction currently.By 2060,the carbon sequestration capacity of forest vegetation will reach or exceed 759.14Mt per y and the CO₂ absorption capacity will reach 2.783 5Gt per y.According to that,China's carbon intensity in 2060 must reduce 95.39% on the basis in 2017 and reach 640t per 100 million yuan.The carbon sequestration capacity of terrestrial vegetation (forest,grassland) will reach or exceed 1.380 3Gt per y and the CO₂ absorption capacity will reach 5.069 3Gt per y.According to that,China's carbon intensity in 2060 must reduce 91.07% on the basis in 2017 and reach 1 152t per 100 million yuan.As a consequence,under the condition that China's carbon intensity is difficult to achieve zero emissions,forest vegetation plays a key role in achieving the goal of carbon neutrality to ensure and improve the carbon sequestration capacity.
