On the chemical level, , before applying conversion, transmission and utilization inefficiencies that all drive trains suffer from in some form, coal releases more CO2 per Joule of raw output than petrol. Up to 50% more, depending on coal quality, according to the tables at https://www.volker-quaschning.de/datserv/CO2-spez/index_e.php https://www.volker-quaschning.de/datserv/CO2-spez/index_e.ph... . The difference is even bigger between coal and natural gas, so if the EV wins the comparison by a considerable but not stellar margin on a gas-powered grid it might still lose on a coal grid. Basically, my point is that even when you are driving an EV you are still driving. We are prone to forget that.
