President Obama will release the final version of the Environment Protection Agency’s (EPA) clean power rules on Monday.
The policy is expected to hand states an emission reduction target for their power sector with the onus then on each state to plan how they will meet that target.
The imminent announcement was trailed in a video released by the White House overnight on Sunday.
In the video President Obama said: “Climate change is not a problem for another generation. Not anymore.
“My administration will release the final version of America's Clean Power Plan, the biggest, most important step we have ever taken to combat climate change.”
The plan will be the centre piece of the US offering at the UN climate change talks in Paris this December. Legal challenges from the coal industry are expected.
US solar trade body, the SEIA, said the final rules would incentivise, for a limited period, the use of solar.
“Solar energy is the most sensible compliance option for states under the Clean Power Plan,” claimed Rhone Resch, president and CEO of the SEIA. “Solar works in all 50 states, has zero carbon emissions, creates more jobs per megawatt (MW) than any other technology, and can be deployed cost-effectively and quickly – all while improving grid reliability,” he claimed.
Democratic presidential nominee Hillary Clinton confirmed she would defend the policy were she to win the 2016 election.
