Less of any type of fossil fuel is a help. In the case of China, the help is incremental, but still.

Not if the fossil fuel is being substituted by another type of fossil fuel, which emits so much more CO2 for unit of energy it provides that the greater thermodynamic efficiency of power station compared to car engine can’t fully make up the difference.

Prior to end of Covid,  it looks like the increasing electric demand created by Chinese EVs are mostly supplied by new renewable generation, with coal generation remaining flat.    So the adoption of EV results in net reduction of CO2 emission across the economy.    However that is less clear now since Xi Jingping has put national security about climate security and new coal fired power plants are being permitted again.
