In 2005, Swedish millionaire Johan Eliasch bought 400,000 acres of the Amazonian rainforest just to preserve its plants and wildlife.
In 2005, Eliasch created the Rainforest Trust and purchased for preservation purposes a 400,000-acre (1,600 km2) rainforest area in the heart of the Amazon rainforest near the Madeira River. In 2006, he co-founded Cool Earth, a charity he co-chairs, which sponsors local NGOs to conserve the endangered rainforest and has over 120,000 registered members.
In 2007 he was commissioned by HM Government to undertake an independent review on the role of international finance mechanisms to preserve the global forests in tackling climate change, 'The Eliasch Review' which was launched by the British Prime Minister Gordon Brown at 10 Downing Street in October 2008. The Eliasch Review has served as a guideline for REDD (Reduced Emissions from Deforestation and Degradation) as part of the international climate change convention.
In June 2008, the Brazilian and international media reported that the company Gethal, owned by Eliasch, had been issued a fine of R$450 million for alleged illegal deforestation in the Amazon region by IBAMA (Brazilian Institute of Environment and Renewable Natural Resources). Gethal was investigated facing a possible fine but after the investigation ended, Gethal was not fined. Eliasch did not own Gethal at the time when the activities under investigation took place.
