Avenida Liberdade (Brazil highway)

The Avenida Liberdade is a four-lane highway currently being constructed in protected Amazon rainforest areas in preparation for the November 2025 COP30 climate summit in Belém, Brazil. The infrastructure project spans over thirteen kilometers through protected rainforest territory, and plans to incorporate several environmental-focused designs including wildlife crossings to allow animal movement, bicycle lanes, and solar-powered lighting systems. The project represents one of numerous development initiatives being implemented to accommodate the anticipated 50,000 attendees, including several world leaders and high-ranking delegates, expected at the climate conference.

The highway's construction generated significant controversy due to its ecological impact caused by its deforesting of a region critical to global carbon absorption and biodiversity preservation.
