At Bali in December 2007 the world accepted an idea Kyoto had refused: pay tropical countries for the carbon in forests they choose not to cut. Norway funded it first, and Brazil, Indonesia, Guyana, and others followed. The credits that grew from it became discredited, so Brazil launched a fund in Belém in 2025 that pays by the hectare with no credits. Brazilian deforestation has fallen, driven mainly by enforcement and weather.
About 84 percent of Guyana's credits come from a high-forest, low-deforestation adjustment, which Guyana defends and critics reject, and consent from Amerindian villages is also disputed. Brazilian criminal cases against carbon dealers are charges only, with no convictions. Enforcement, rainfall, and prices all contributed to falling deforestation.
