The Amazon Soy Moratorium is a voluntary private-sector agreement under which soy traders committed not to buy soy from farms that had any Brazilian Amazon deforestation past a cutoff date of 2008. After the moratorium, Amazon forest annual loss rates declined by over 80%, with a quarter of that reduction being directly attributable to the moratorium alone; this represents an aggregate approximate 3.2 million ha of land over the period 2008-2025. From 2006 to 2023, 97.6% of Amazon deforestation was not associated with soy, despite a 4x growth in soy area in the biome. It was hailed by many civil society groups as vital for slowing deforestation.
