The president compared the requirement of cutting carbon emissions by 32 percent to taking 166 million cars off the road.

In a new push to confront climate change, President Obama is announcing new standards that would cut the amount of carbon pollution produced by America's power plants.
"These are the first-ever national standards that address carbon pollution from power plants," according to the Environmental Protection Agency, which adds that power plants are the largest source of carbon pollution in the U.S., generating 32 percent of the total emissions.
Key elements of the Clean Power Plan include a requirement that would cut the power industry's carbon pollution by 32 percent below 2005 levels in the next 15 years. The plan also seeks to boost renewable energy.
The White House says that between now and 2015, the changes will mean better health for Americans – preventing up to 3,600 premature deaths – along with bringing energy savings for U.S. consumers.

NPR's Scott Horsley reports:
"The final version of the EPA's clean power plan requires somewhat deeper cuts in power plant emissions than a draft version made public a year ago. The power plant rule is the centerpiece of President Obama's broader climate agenda. And he's urging other big countries to take similarly aggressive action in advance of an international climate summit in Paris later this year.
"Opponents, including Senate Republican Leader Mitch McConnell, have promised to fight the climate rule, and they're urging states not to comply with the EPA regulation.
"The final rule does provide a somewhat more flexibile timeline for power companies, with the deadline for action pushed back two years to 2022."
The president is announcing the plan along with EPA Administrator Gina McCarthy and Surgeon General Vivek Murthy.
