Analysis - Matt McGrath, environment correspondent
President Obama's Clean Power Plan is the practical aspect of his lofty rhetoric on tackling global climate change.
Late last year, the President announced, with his Chinese counterpart Xi Jinping, that both nations would significantly cut their carbon emissions. He also pledged, earlier this year, that the US would adopt new targets on limiting warming gases in an effort to secure a UN climate deal. To make both these pledges happen, coal fired electricity across every US state will have to be reduced.
These steps will also shore up US credibility in the international climate talks arena.
Many nations harbour suspicions about the US, as the country refused to ratify the Kyoto Protocol - the world's previous attempt to rein in carbon dioxide.
There is also lingering suspicion among smaller countries after the debacle of Copenhagen in 2009, when Obama and other leaders attempted to foist a deal on the 196 parties involved in the UN process. It didn't end well.
The President's new plan comes at a crucial time in the run-up to Paris, where a deal is expected to be signed in December. The UN is struggling to cut down a negotiating text that still runs past 80 pages, and only 49 countries have so far made public their declarations. The US Clean Power Plan will be a boost to the process and to efforts to get the others to declare their hands.
Each US state will have an emission-cutting goal assigned to it and must submit a proposal to the Environmental Protection Agency on how it will meet the target.Each US state will have an emission-cutting goal assigned to it and must submit a proposal to the Environmental Protection Agency on how it will meet the target.
