After a week-long conference in Paris, representatives from the United States and 200 other nations signed an unprecedented climate agreement that could have big implications for Texas.

According to the Texas Tribune, the accord would require almost every country to cut carbon emissions.

The agreement could have big implications in Texas, the nation’s number one energy producer, where Attorney General Ken Paxton is already suing the Environmental Protection Agency (EPA) over President Obama’s Clean Power Plan.

The Clean Power Plan would require power plants across the state to slash their carbon emissions.

Paxton has cast doubt on whether the federal government has the ability to enforce such agreements, according to the Tribune.
