Obama administration unveils plans to cut 1 billion tons in carbon emissions by 2027

The Obama administration announced big cuts in carbon emissions for heavy-duty trucks on Friday. The Environmental Protection Agency and the Transportation Department proposed a 24-percent cut in carbon emissions, set to take full effect by 2027. One environmental group estimates this reduction equates to about 1 billion tons of carbon emissions. The proposal, which would alleviate levels of carbon pollution contributing to global warming, is the latest installment in the Obama administration's efforts to cut down on greenhouse gas emissions.
