You operate with the premise that burning coal or natural gas produces same emissions as burning diesel or petrol in the vehicle engines. That's not true. Especially natural gas is very good source in terms of CO2 emissions (and near perfect source in terms of other unwanted emissions like NOx, SOx or solid particles which are other very problematic substances produced by vehicles). Even black coal is better in terms of CO2 emissions per energy unit than petrol or diesel.

In fact CNG in terms of emissions is very clean source of energy. The emissions of CO2 are roughly 50% per same energy, emissions of SOx near non existent, emissions of solid particles non existent at all, emissions of NOx are roughly 20-30%.

Another good thing about CNG is that it can be used by vehicles directly without any major issues.

Another point which You fail to see is that especially in the city traffic the combustion engines often produce completely useless energy. They basically only warm up their surroundings while the vehicle stands still. This is totally wasted energy with only negative impacts to the environment.
