Brazil Soy Moratorium: Collapse Threatens Amazon Deforestation | Science

For nearly two decades, a landmark agreement aimed at protecting the Amazon rainforest from soy-driven deforestation has been unraveling. The so-called “soy moratorium,” established in 2006, was a voluntary pact among commodity traders to refrain from purchasing soybeans grown on land deforested after July 1, 2008. While credited with significantly reducing forest clearing for soy cultivation, the agreement is now facing collapse due to changing political and economic pressures in Brazil.

The moratorium emerged in response to growing concerns about the environmental impact of soybean farming in the Amazon. A 2006 Greenpeace investigation revealed links between soy production in illegally deforested areas and major U.S. Commodities companies like Cargill, Bunge, and ADM. Under pressure from environmental groups and consumers, these companies agreed to the moratorium, effectively creating a self-imposed restriction on sourcing soy from newly deforested land.

The success of the moratorium is well-documented. Studies, including a 2020 study published in the journal Nature Food, demonstrate that the agreement, in conjunction with public policies, contributed to a substantial reduction in deforestation rates in the Brazilian Amazon between 2003 and 2016. However, the arrangement was always voluntary, and its future has been uncertain for some time.

Recent developments signal a significant weakening of the moratorium. On January 1, 2026, a new law took effect in Mato Grosso, Brazil’s largest soybean-producing state, eliminating tax benefits for companies participating in the agreement. This law, backed by soybean producers and a majority of Mato Grosso’s lawmakers, effectively incentivizes companies to abandon the moratorium. Following the law’s enactment, the Brazilian Association of Vegetable Oil Industries (ABIOVE), representing some of the world’s largest soy traders, announced its withdrawal from the agreement.

According to André Lima, secretary for deforestation control and land‑use planning at the Ministry of the Environment, the withdrawal of ABIOVE essentially marks the end of the moratorium. “If they withdrew from the pact, then a marriage with only one husband or only one wife is no longer a marriage, right?” he stated. While no participant has formally declared the agreement over, the departure of key industry players renders it largely ineffective.

The decision to dismantle the moratorium has sparked criticism from environmentalists and government officials. Concerns are mounting that the move will lead to a resurgence in deforestation, undermining President Luiz Inácio Lula da Silva’s commitment to end deforestation by 2030. The weakening of the moratorium also threatens to reverse the gains made in preserving the Amazon rainforest, a vital ecosystem for global climate regulation, and biodiversity.

The situation is further complicated by a ruling from Brazil’s competition authority, the Conselho Administrativo de Defesa Econômica (CADE), in 2025, which deemed the moratorium “anticompetitive.” This ruling, coupled with the regulatory sanctions imposed by state governments, has created a challenging environment for maintaining the agreement.

Despite the setbacks, some experts argue that the moratorium has served its purpose. Reports indicate that soy production on lands cleared *before* July 1, 2008, as well as on pasture and savannah lands, has quadrupled since 2006. This suggests that soy production can continue to expand without necessarily requiring further deforestation. However, this expansion onto existing agricultural lands raises separate environmental concerns, such as the conversion of native grasslands.

Glenn Hurowitz, founder of Mighty Earth, an environmental advocacy group, argues that dismantling the moratorium is “entirely self-defeating.” He contends that the commercial success of these companies has been reliant on the agreement for the past 20 years, and that abandoning it could create marketing and market access challenges.

The future of the Amazon rainforest remains uncertain. The collapse of the soy moratorium underscores the complex interplay between economic interests, environmental protection, and political will. Strengthening multilateral partnerships between businesses and governments will be crucial to ensuring the long-term conservation of this vital ecosystem. Without continued commitment to sustainable agricultural practices and robust environmental regulations, the Amazon faces an increasing risk of deforestation and its associated consequences.
