Cool Earth aims to fight global warming through fighting deforestation in the rainforest.
Cool Earth aims to reduce the impacts of climate change by combating deforestation in a variety of rainforest locations — including the Ashaninka and Awajun Projects in Peru, the Lubutu project in the Democratic Republic of Congo, the Orangerie Bay Project in Papua New Guinea, the Awacachi Project in Ecuador (completed), and the Madeira Project in Brazil (completed).
Cool Earth does not buy rainforest directly, but rather establishes sustainable agreements with local communities to ensure that local communities opt not to sell the nearby forest to loggers. These agreements aim to improve the lives of these communities to the point where they can withstand pressure to sell to loggers, and are based on the needs and specific requests of the community. They have previously involved support for local industries such as cacao and coffee, technical assistance, funding for local schools, provision of boats for emergency health evacuations, and targeted maternal healthcare. Based on this, Cool Earth’s work also contributes to economic empowerment at a community level.
We don't currently have further information about the cost-effectiveness of Cool Earth beyond it doing work in a high-impact cause area and taking a reasonably promising approach.
