What if major economies all just agreed to quit fossil fuels — together? To date, 13 countries have signed a fossil fuel nonproliferation treaty. The biggest is Colombia, which has a $40 billion economic transition plan to build up green sectors and replace oil and gas revenue. Now Colombia is hoping to recruit other large economies to follow suit.

During a conversation at Climate Week in New York, Akshat Rathi sat down with Colombia’s environment minister, Susana Muhamad, and Brazil's chief climate negotiator, Liliam Chagas, to talk about what it will take for more nations to combat climate change. Brazil has not joined the treaty, yet, but as the designated host of COP30 in 2025, the country has signaled that it, too, wants to be a leader on climate change.
