The Noel Kempff Mercado National Park, in northeastern Bolivia, spans over 1.5 million hectares (over 3.7 million acres) in one of the most biologically diverse areas in the world. Through a unique partnership, the Government of Bolivia, the Friends of Nature Foundation (FAN), The Nature Conservancy and three energy companies (American Electric Power, PacifiCorp and BP Amoco) have teamed up to jointly implement the US $11 million Noel Kempff Mercado Climate Action Project--the largest forest based carbon project in the world.
