Why natural gas makes global warming worse GreenBiz
Here's the trouble: Carbon dioxide is the main greenhouse gas, but it's not the only one. Another one — present in smaller amounts, but far more potent — is CH4, otherwise known as methane, the primary component of natural gas. If you burn natural gas, you get less carbon dioxide than with coal.
