The carbon neutrality feasibility of worldwide and in China's transportation sector by E-car and renewable energy sources before 2060

Fuel cars are the major contributor with 41 % released emissions, which is about 7.3 billion metric tons (BMt) of CO₂ produced in 2020 by the international transportation sector. The most significant polluted regions are U.S.A with 0.731BMt, China with 0.545BMt, and Europe with 0.437BMt of CO₂ emissions annually. The four provinces of China named Guangdong, Shandong, Jiangsu, and Henan releases considerable CO₂ emissions due to the enormous number of F-cars. This paper discusses the reason of banning F-car, fossil fuel and introduce of E-car and renewable energy as fuel for mitigation of carbon emission in transport sector. Chinese government set the goal and promotion policies for manufacturing companies and consumers for E-car promotion such as tax exemption, innovation technologies for high-range cars, financial support, charging pile construction, free parking, and fewer traffic restriction, etc., are assisting to encourage buyer and help to achieve the target of CO₂ reduction by 2060. Consequently, the Li-ion and SSBs batteries are more efficient to use in E-cars and eco-friendly than other battery types. The bottom-up accounting framework analysis reflects the results of all national quick response policies and indicated the mitigation of CO₂ emissions from global were decreased from 2.6BMt to 0.006BMt 2010 to 2060, and use of non-renewable energy sources decline from 55 % to 4 % while use of renewable energy sources rises from 42 % to 93 % from 2030 to 2060 due to launching E-cars and devised policies. This research helps to understand the prospects of policies and changes in energy sources to meet the target of CO₂ mitigation from transportation sector globally and in China.
