The Sustainable Development Institute (SDI) works to transform decision-making processes in relation to natural resources and to promote equity in the sharing of benefits derived from natural resource management in Liberia. The  organization’s vision is a Liberia in which natural resource management is guided by the principles of  sustainability and good governance and benefits all Liberians. Its activities cover a range of  crosscutting issues including: governance and management; the environment; state and corporate social responsibility; economic and social justice for rural populations; and the democratic participation of ordinary people in government management of natural resources. The organization received the Goldman Environmental Prize, the world’s largest prize honoring grassroots environmentalists for outstanding environmental achievements, in 2006.
