John Kerry: “I think trying to get a deal here is a once-in-a-lifetime opportunity.”

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

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 now giving less than a lot of other countries are doing in order to help particularly on climate.

You cannot just sit there anywhere and wish that things are going to be as they have been historically.
