# Brazilian legislative opposition to indigenous rights > Live situation record from CLSTR: https://clstr.news/situations/brazilian-legislative-opposition-to-indigenous-rights > Updated: 2026-10-09T04:00:00.000Z. Sources: 30. Developments: 4. Research and data from advocacy groups indicate a sustained legislative trend in the Brazilian Congress directed against indigenous rights and environmental protections. Analysis by the Missionary Indigenous Council (Cimi) shows that between January 2019 and July 2024, approximately 67.56% of votes cast by senators and federal deputies were against indigenous rights. The Liberal Party (PL) was identified as the most opposed, with 95.9% of its votes cast against these interests. Following the 2026 elections, the Liberal Party emerged as the largest party in both the Senate and the Chamber of Deputies. Organizations such as Amazon Watch and the Articulation of Indigenous Peoples of Brazil (Apib) warned that this congressional balance favors interests supporting mining on indigenous lands and the weakening of environmental regulations. On October 5, 2026, the Organization of American States (OAS) described the election process as a “peaceful civic journey” but warned of intense polarization. New analysis by the Observatório do Clima regarding the incoming 58th Legislature (2027-2031) indicates a significant decline in alignment with environmental and climate agendas. According to the environmental convergence index developed by the Instituto Democracia e Sustentabilidade, 68.9% of newly elected lawmakers in both houses fall into “low” or “very low” convergence categories. The Senate shows a particularly sharp divergence, with 79% of its members classified in these categories. Suely Araújo, Public Policy Coordinator at the Observatório do Clima, warned that this shift could jeopardize environmental protections, potentially leading to the weakening of agencies and amnesty for land grabbers. A study by Observatório do Clima further specifies that 64 of the 81 Senate members and 345 of the 511 Chamber of Deputies members show little to no commitment to environmental issues. Parties including the PL, Novo, Republicans, Progressistas, and União Brasil were identified as having weak environmental credentials. ## Claims - 68.9% of the members of the 58th Legislature (2027-2031) have low or very low environmental convergence.
