On Monday, President Obama launched his Clean Power Plan designed to cut emissions from the power sector by 32% in 2030, against a 2005 baseline.
It's more ambitious than a draft, published for comment last year, which targeted a 30% reduction. Obama says it is the "single most important step" the US has taken to tackle climate change.
