Colombia has formally joined an alliance of nations calling for a fossil fuel non-proliferation treaty to prevent the “omnicide of planet Earth”, the country’s president announced at Cop28.

At the climate summit in Dubai, Gustavo Petro has said his country would join a group of nations calling for a new body to manage a global transition away from the primary driver of global heating, akin to previous treaties to reduce nuclear weapon arsenals and landmines.
