FLAGSTAFF, Ariz. (AP) — Arizona would be tasked with coming up with a plan to cut carbon dioxide emissions by about half under a proposal released Monday by the U.S. Environmental Protection Agency.
The targets vary in other states, which will have until 2017 and 2018 to submit cleanup plans or let the federal government do it on their behalf.
Here's a look at Arizona:
— Arizona's emissions from electric power plants would be reduced by 48 percent by 2030, based on 2012 levels. The state's power plants pumped out more than 37 million metric tons of carbon dioxide emissions that year.
— Arizona gets 36 percent of its electricity from coal-fired power plants, nearly 29 percent from nuclear, 27 percent from natural gas and 6 percent from water. Solar and wind energy and power generated by petroleum represent less than 1 percent each of the state's portfolio. The national average is 26 percent from gas and 40 percent from coal.
— Much of the focus on reducing emissions nationally is centered on cleaning up or replacing coal-burning power plants. The EPA said the most cost-effective way to achieve the goals is for states to work together.
