>
> Carbon dioxide emissions from the US’s energy sector fell in 2015 and now stand at 12% below 2005 levels, a drop mainly driven by the continuing collapse of the coal industry.
>
> Americans’ energy consumption resulted in the release of 5.2bn tons of CO2 last year, according to the US Energy Information Administration <http://www.eia.gov/totalenergy/data/monthly/pdf/mer.pdf> (EIA), down from 5.4bn tons in 2014. The 12% cut since 2005 has come during a period in which the US economy has, adjusting for inflation, grown by 15%.
>
> About a third of America’s emissions come from energy consumption, with transportation, industrial activity and agriculture also making significant contributions <https://www3.epa.gov/climatechange/ghgemissions/sources.html>.
>
> A flurry of coal plant retirements and an increase in the production of natural gas and renewable energy have pushed the US further towards the federal government’s goal <https://www.whitehouse.gov/the-press-office/2015/03/31/fact-sheet-us-reports-its-2025-emissions-target-unfccc> of slashing emissions by between 26% and 28% by 2025, prompting some analysts to call for stronger measures to accelerate the decline.
>
> “I think we have still got some work to do,” said Colleen Regan, head of North American environmental markets at Bloomberg New Energy <http://www.theguardian.com/environment/energy> Finance. “I think Obama has done a lot but the next president will need to do more to bring emissions down in transport and industry.
>
> “Maybe we should be asking the power sector to do more. It’s easier to reduce emissions in the power sector than in industry and we should be asked for the cheapest form of abatement. With the drops we’ve seen even without the Clean Power Plan, there’s scope to do more.”
>
> According to the EIA, the 2015 fall in emissions was largely due to “decreased use of coal and the increased use of natural gas for electricity generation”. Last year, coal made up 80% of all retired electricity-generating capacity <https://www.eia.gov/todayinenergy/detail.cfm?id=25272>, with plants shutting down across the midwest and south, particularly in Ohio, Georgia and Kentucky.

> According <http://content.sierraclub.org/coal/victories> to the Sierra Club, 232 coal plants have been retired in total. The closures have become enmeshed in the US presidential race, with presumptive Republican nominee Donald Trump last week donning a miner’s helmet <http://www.ibtimes.com/political-capital/west-virginia-primary-2016-donald-trump-seizes-coal-country-voters-promise-revive> in West Virginia and promising to get laid-off miners back to work.
>
> However, the low price of natural gas and ageing infrastructure has caused seemingly intractable headaches for the coal sector, including the company Peabody Energy, which went from market leader to bankruptcy in April <http://www.theguardian.com/environment/2016/apr/13/worlds-largest-coal-producer-files-for-bankruptcy-protection>. US Environmental Protection Agency rules <https://www3.epa.gov/mats/actions.html> to curb mercury and other toxins at coal plants, which kicked in last year, have also had an impact.
>
> This trend could be accelerated by the implementation of the Clean Power Plan, which places limits upon power plant emissions. The plan is currently on hold <http://www.theguardian.com/environment/2016/feb/09/climate-change-supreme-court-barack-obama-plan> pending a supreme court challenge from states that claim it will place an undue cost upon the public.
>
> Regan said the plan was a “backstop” that may not prove crucial if natural gas prices remain favorable.
>
> “Natural gas isn’t clean, but it’s much cleaner than coal, so I think we are in pretty good shape,” she said. “If the natural gas price moves back up again, it becomes a concern.”
>
> Wind power, primarily in Texas, Oklahoma and Kansas, expanded the most <http://www.eia.gov/todayinenergy/detail.cfm?id=25492> of all clean technologies in 2015, followed by solar. However, renewable sources of energy are moving up from a low base.
>
> “This progress puts America on a path toward meeting our international commitments, and is a direct result of moving our nation beyond coal and increasingly replacing it with clean energy like wind and solar,” said Mary Anne Hitt, director of the Sierra Club’s “beyond coal” campaign.
>
> “Our transition away from coal and toward a clean energy economy is one of the great climate success stories of the past decade, and it will continue to shape America’s energy landscape for decades to come as our grassroots movement to get off of fossil fuels continues to grow.”
