Welcome to Zero. I am Akshutarati. This week, the country's quitting fossil fuels.

It was hot and muggy and busy.

The United Nations General Assembly was also taking place,

Do we need carbon removal?

Do we need geoengineering?

Where are we going to get the money?

climate, birding even. I could go on. One thing that stood out to me though was that the

conversations tended not to be about what we must do, but how do we do it and how do we do it

bigger? At scale, be bolder. One of those big, bold

propositions is a fossil fuel non-proliferation treaty. Just like nuclear non-proliferation, the idea is

getting countries to agree to stop expanding fossil fuel production.

So far, 13 countries are on board. The biggest is Colombia.
