The United States Forest Service’s Office of International Programs and the US Agency for International Development (USAID) have supported the development of the Green Value financial analysis tool and the training activities since 2008, when Dr. Thomas Holmes and Dr. Shoana Humphries began working on the worksheets and User's Guide. Other early supporters of the Green Value tool were IMAZON, IEB, and IFT, which provided useful feedback on the tool when it was first being used in Brazil. In 2012, Earth Innovation Institute (EII) launched the Strengthening Community-based Forest Enterprises in the Tropics project and chose representatives of eleven non-profit organizations in the Amazon region to train as trainers in the Green Value tool. Since 2013, many governmental organizations helped support Green Value tool workshops. These organizations are listed below.
