The Amazon, the world’s largest tropical forest, is critical in the fight against climate change because it is a carbon sink, absorbing more carbon dioxide than it emits. But there’s huge variation locally. New WRI analysis finds that forests managed by Indigenous communities in the Amazon are strong net carbon sinks, collectively removing 340 million tonnes of carbon dioxide from the atmosphere each year, equivalent to the UK’s annual fossil fuel emissions. Forests outside the Amazon’s Indigenous lands, however, are collectively a carbon source due to significant forest loss. Read more.
