The Nature Conservancy is a private, non-profit organization established in 1951 to preserve the plants, animals and natural communities that represent the diversity of life on Earth by protecting the lands and waters they need to survive. With its headquarters in Arlington, Virginia, TNC has chapters in every U.S. state and a network of international conservation partners. To date, TNC and its more than one million members have protected more than 11 million acres in the United States, and have helped protect more than 50 million acres in Latin America, the Caribbean, Canada, Asia and the Pacific.

TNC has in-depth experience in the planning and implementation of international climate action projects, including operational projects in Belize and Bolivia. In Belize, the Conservancy is working with corporate partners, including AEP as a minor investor, and the Programme for Belize on the Rio Bravo Carbon Sequestration Project. The Noel Kempff Mercado Climate Action Project in Bolivia is a collaborative effort with AEP, Pacificorp, BP, the Friends of Nature Foundation and the Bolivian government to protect more than 1.5 million acres of Bolivian rainforest. It is the largest such project in the world.
