Do you have a source that natural gas is the largest carbon emissionss contributer? Genuinely curious, because over here in Germany gas companies (Gazprom.. ;)) market themselves as the opposite and the same argument is used for cars running on natural gas. I know that's just PR, but I thought it produces less emissions because it burns more efficiently than other fossil fuels.

CO2 emissions are essentially the same, but other pollutants are much lower. There are less contaminants in natural gas, so burning it in a cheap and inefficient engine like a bus in a city is better than using petrol.

I should have written "one of the largest", not the largest, my apologies.
