EXCERPT:
KERRY: "If you offset your carbon -- it's the only choice for somebody like me who is traveling the world to win this battle. I negotiated the Paris Accords for the United States. I've been involved with this fight for years. I negotiated with President Xi to bring President Xi to the table so we could get Paris. And, I believe, the time it takes me to get somewhere, I can't sail across the ocean. I have to fly, meet with people and get things done. But, what I'm doing, almost full time is working to win the battle on climate change, and in the end, if I offset and contribute my life to do this, I'm not going to be put on the defensive."
