Lisa P. Jackson, EPA "At the end of the day, what's most important is that we have a single, national standard that is achievable, but that is aggressive and cost-effective." - Charles Territo, Auto Alliance This program lessons our dependence on oil and is good for America and good for the planet. Ray LaHood, DOT Slide 11 11 Results Forecasted benefits (2012-2016) 960M metric tons of CO2 1.8B barrels of oil EPA was able to play leadership role in driving a priority public policy initiative Saving annual electricity for 117M homes Preserving 9M acres of forest from deforestation Removing annual emissions from 249 coal power plants
