"The Environmental Protection Agency's plan to roll out regulations on planet-warming gases may hit a snag in the coming months -- opposition from environmentalists. While industry groups are mounting major legal challenges to the agency's ability to regulate greenhouse gases, the EPA's decision to scale back the number of pollution sources subject to these new rules has raised the ire of greens who worry the agency isn't being aggressive enough.

Bill Snape, senior counsel at the Center for Biological Diversity, says the EPA is guilty of "extreme backtracking" on greenhouse gas regulations. The group has announced its intention to sue the EPA over the coming climate regulations, which it deems too weak."
