Relative Pollution

Natural gas is cleaner than other fossil fuels, but it still emits 50.30 grams of CO₂ greenhouse gas per megajoule of energy produced. Green energy sources produce none. To compare, automobile gasoline emits 67.07, fuel oil emits 81.26 and anthracite coal emits 97.59 almost twice as much as natural gas. source. A megajoule is sufficient heat energy to boil dry about 400 mls (1.69 US cups) of water.
