To save you all a google: it's made from natural gas, at a pretty significant energy loss compared to just burning the gas. It generates about 4 times more co2 than burning diesel.

Any evidence to your claim?

Natural gas is a relatively clean burning fossil fuel

Burning natural gas for energy results in fewer emissions of nearly all types of air pollutants and carbon dioxide (CO2) than burning coal or petroleum products to produce an equal amount of energy. About 117 pounds of CO2 are produced per million British thermal units (MMBtu) equivalent of natural gas compared with more than 200 pounds of CO2 per MMBtu of coal and more than 160 pounds per MMBtu of distillate fuel oil. The clean burning properties of natural gas have contributed to increased natural gas use for electricity generation and as a transportation fuel for fleet vehicles in the United States.

Burning natural gas isn't so awful but getting it out of the ground and to the place where is needs to be burned is always overlooked. It's a gas, it wants to escape and much of the infrastructure leaks and so a great deal is lost before its used. I walk around Boston and no joke you just SMELL it all the time because the infrastructure is so old. Natural gas is also mostly methane which when leaked is 80 times more potent than CO2. Furthermore much natural gas needs to be transported on ships to be uses. To summarize there is no 'greener' fossil fuels it's all to be avoided if possible.
