greater investment in our energy sector and smarter energy efficiency, by working with the world to achieve a climate agreement by the end of this year we can do more to slow and maybe even eventually stop the carbon pollution that's doing so much harm to our climate. so this is the right thing to do. i want to thank, again, gina and her team for doing it the right way. over the longest engagement process in epa history, they fielded more than 4 million public comments. they worked with states. they worked with power companies and faith groups and people across our country to make sure that what we were doing was realistic and achievable but still ambitious. and some of those people are with us here today. so tonya brown, wave go ahead. there's tonya.
