Environmental groups said Saturday they would give U.S. authorities more time to submit a plan to regulate carbon dioxide, amid the threat of a possible lawsuit.

The Environmental Defense fund and other groups are in negotiations with the U.S. Environmental Protection Agency on a deadline to withhold legal action until November 30, according to Reuters.

The groups wrote a letter to the U.S. Department of Justice late Friday stating they had agreed to give the EPA more time “In light of the progress made to date.”

The EPA initially proposed in March to required the oil and gas industry to report emissions of greenhouse gases starting in 2012, calling for a disclosure of methane and carbon dioxide emissions from on-shore and off-shore production facilities as well as processing and transmission.

However those rules have been met with resistance from Republicans in the U.S. House of representatives and businesses who say the rules would be overly expensive and kill jobs.
