Brazil Supreme Court Upholds Soy Moratorium Constitutionality While Validating State Tax Penalties

Brazil’s Supreme Court ruled that the voluntary soy moratorium— a pact barring purchases of soy grown on Amazon land cleared after July 2008—remains constitutional. At the same time, the court affirmed state laws that deny tax incentives to farmers who comply with the agreement. The dual ruling leaves the moratorium’s legal status intact but permits states to penalize participants through tax policy.

The moratorium, launched in 2006 after pressure from environmental groups and international buyers, helped cut deforestation in high-risk Amazon areas by roughly 35 % during its first decade, according to a study published in *Science*. Brazil produces about 40 % of global soy, with 171.5 million metric tons harvested in the 2024-25 season. Major grain traders withdrew from the pact in January after several soy-producing states revoked tax benefits for compliant companies. Scientists warn that ending the agreement could trigger up to 1.4 million hectares (3.5 million acres) of additional deforestation over the next decade—an area comparable to Portugal.

• Angela Barbarulo, legal coordinator for Greenpeace Brazil, praised the court’s acknowledgment of the moratorium’s constitutionality but warned that endorsing state tax penalties “undercuts” its effectiveness.

• ABIOVE (Brazilian Association of Vegetable Oil Industries) said the decision ends years of legal uncertainty and validates voluntary sustainability commitments, while noting the moratorium is now referenced in the past tense, suggesting limited prospects for revival.

• The Mato Grosso Soy Producers Association, which opposed the moratorium, hailed the ruling as reinforcement of state authority to resist private-sector environmental restrictions and pledged to continue opposing any future agreements that replicate the moratorium’s limits.

If state tax penalties deter participation, the market could see a resurgence of soy sourced from newly cleared Amazon land. The *Science* study projects that such a shift may add up to 1.4 million hectares of deforestation in the next ten years, expanding the frontier of legal clearing and threatening the rainforest’s climate-regulating functions.
