Soy traders blacklisted Amazon farms cleared after a cutoff

In April 2006 Greenpeace published 'Eating up the Amazon,' tracing soy grown on newly deforested Amazon land through grain terminals like Cargill's at Santarém into the supply chains of McDonald's chicken feed and European supermarket shelves. In the two years before the report, nearly 30% of new soy planted in the Amazon biome had come from land cleared specifically for that purpose. McDonald's and a coalition of European retailers, facing consumer pressure they could not verify their way out of, froze new supplier relationships in the region and demanded the traders themselves fix it.

The available fix at the time was farm-by-farm certification — audit individual growers and label the compliant ones sustainable — which meant years of inspections across a region larger than Western Europe while deforestation continued underneath the paperwork. The traders had something certifiers didn't: between them, Cargill, ADM, Bunge and the rest of ABIOVE's membership bought virtually all the soy that left the Amazon. If they agreed with each other on one rule, no farmer's cleared land had anywhere left to sell its harvest.

Traders jointly refused to buy soy from land cleared after a cutoff, making deforestation unsellable; shared rule turned every purchase into enforcement.

ABIOVE's members bought nearly all Amazon soy, so a farmer with a blacklisted field had no meaningful buyer.

The shared rule turned every trader's purchase into every other trader's enforcement, preventing any one trader from breaking ranks.

Satellite monitoring was cheaper and faster than farm-by-farm certification, making compliance verification feasible.

The exclusion changed the economics of clearing land before planting, not just after harvest.

When bad behavior is too dispersed for any single buyer to police, get all major buyers to agree on one shared exclusion rule, making the whole buying side a single counterparty.

Deforestation-linked soy expansion fell from ~30% before 2006 to roughly 1% after; the pact was renewed indefinitely in 2024. The Soy Moratorium became the template for Brazil's parallel Cattle Agreement and for commodity-driven deforestation pacts studied globally as a rare case of effective private hybrid governance, though researchers have also documented leakage as cleared land shifted toward pasture before conversion to soy, a gap the moratorium's satellite monitoring was later extended to try to close.
