John Kerry: “The absence of diplomatic effort is almost a guarantee of failure.”

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.

We are not, I have not, President Biden has not, we are not saying to people, you should not fly.

In terms of global challenges and U.S. interests, yes.

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