Amazon Watch is a 501(c)(3) nonprofit organization founded in 1996 to protect the rainforest and advance the rights of Indigenous peoples in the Amazon Basin. We partner with Indigenous and environmental organizations in campaigns for human rights, corporate accountability, and the preservation of the Amazon's ecological systems. Indigenous communities have lived in balance with the Amazon for millennia and have protected this ecosystem — the largest and most bio-culturally diverse tropical rainforest in the world — from destruction due to colonization and continued extraction. Oil and gas drilling, logging, poaching, road-building, damming and mining all have highly destructive impacts on the rainforest and Indigenous peoples of the Amazon Basin. Amazon Watch has worked in solidarity with Indigenous partners for 25 years to halt and hold accountable the global drivers of Amazon destruction, advance and amplify Indigenous rights, resistance, and solutions to protect the Amazon Basin, and support global movement-building for Pan-Amazon protection and climate justice. Amazon Watch uses a range of tactics including media outreach, direct dialogue with corporate and development bank management, mobilizing shareholder pressure, legal and media capacity-building among Indigenous communities, monitoring, documenting and publicizing the negative impacts of specific projects, and calling for the establishment of rainforest reserves to protect the Amazon's biodiversity and rainforest communities. Considering the Amazon is at a tipping point, we commit to addressing root causes and threats to the Amazon and seek systemic solutions while opposing false solutions like carbon offsets. We recognize that the systems that continually violate human rights also destroy the Earth and must be dramatically transformed or abolished. At Amazon Watch, we commit to working in solidarity with Indigenous peoples and a growing global movement calling for urgent action to permanently protect the Amazon, defend the defenders, and advance climate justice.
