John Kerry: “I do not believe it is the only way.”

The message coming out of this COP is, we are moving away from fossil fuels. We are not turning back. That is the future.

What a shame for our country that that happened.

People think this is now, you cannot reverse it, it is irreversible.

The message is, let's find a way to be able to make sure when we fly, we're not leaving emissions that we cannot capture.
