Colombia’s economy is dependent on fossil fuels, which account for about half of its exports. But at the UN climate summit this weekend, Gustavo Petro, the country’s president, committed to stop the expansion of coal, oil and gas exploitation and reorient his nation away from such “poisons”. Colombia is the first big economy to endorse a fossil fuel non-proliferation treaty. This is a sensible, globally significant step – which raises the question of why other carbon-exporting OECD members, such as Britain, shouldn’t follow suit.
What is crazy is that governments plan to produce more than double the amount of fossil fuels in 2030 that is consistent with a “safe” global temperature rise of 1.5C. The paradox the treaty seeks to address is that the Paris agreement does not mention the fossil fuels responsible for global heating. But a handful of nations could show how phasing out fossil fuels can lead to sustainable green development and rebut the absurd denialism of Sultan Al Jaber, the oil boss and Cop28 president. There are precedents: the 1997 mine ban treaty began with few backers, but was later ratified by 164 countries.
