In March 2018, the "Brazzaville Declaration" was signed to promote better management and conservation of the Cuvette Centrale, a region in Congo Basin and primarily in DRC. It is the world's largest tropical peatland, made up of swamp forests. Conservation of this area is important for the survival of megafauna, and also critical to the world's climate. Burning the peat would release too much carbon and raise the earth's temperature. The declaration to save peatlands as the world's largest terrestrial organic carbon stock was signed by Democratic Republic of the Congo, the Republic of the Congo, and Indonesia, which also has peatlands.
