When Front Range residents look to the skies for the next few weeks, they may see something unusual – a NASA P-3 airplane buzzing just a thousand feet above.

The plane is one of three research aircraft plying the skies, as scientists from NASA and the National Center for Atmospheric Research work to learn more about air pollution in Colorado.

The Obama administration said Monday that it intends to aggressively reduce carbon-dioxide emissions, or greenhouse gas pollution, produced by power plants in the United States. To boost these ambitions, the White House will partner with the Environmental Protection Agency (EPA) to enforce varying rules state-by-state to be carried out by power plants that produce the gases.

If successfully implemented, the regulations will deliver a 30 percent decrease in carbon emissions by 2030.

EPA Unveils New Proposal Targeting Greenhouse Gases

Originally published on Mon June 2, 2014 9:52 am

The EPA is proposing rules that would govern carbon dioxide gas emissions by U.S. power plants. Here, coal is transported via conveyor belt to the coal-fired Jim Bridger Power Plant outside Point of the Rocks, Wyo., in March.

New federal regulations announced Monday aim to reduce carbon dioxide emissions from power plants by 30 percent by 2030.

The draft proposal from the Environmental Protection Agency has sparked opposition from industry groups who say the changes would be prohibitively expensive. But the proposal's backers say the rules are needed to cut carbon pollution that scientists say contributes to climate change.
