After failing to get climate-change legislation through Congress, the Obama administration plans on pushing through its environmental policies through other means, and Republicans are ready to put up a fight.
On Jan. 2, new carbon emissions limits will be put forward as the Environmental Protection Agency prepares regulations that would force companies to get permits to release greenhouse gases under the Clean Air Act.
Critics say the new rules are a backdoor effort to enact the president's agenda on global warming without the support of Congress, and would hurt the economy and put jobs in jeopardy by forcing companies to pay for expensive new equipment.
"They are job killers. Regulations, period -- any kind of regulation is a weight on economy. It requires people to comply with the law, which takes work hours and time, which reduces the profitability of firms. Therefore, they grow more slowly and you create less jobs," said environmental scientist Ken Green of the conservative American Enterprise Institute.
