The International Institute for Environment and Development (IIED) is an independent policy research institute (think tank) whose stated mission is to "build a fairer, more sustainable world, using evidence, action and influence in partnership with others."^[1] Its director is Dr Tom Mitchell.

IIED is one of a small group of independent, not-for-profit organisations that has provided core concepts and methods for thinking about sustainability and social change. IIED's main way of working is through partnership with like-minded organisations in Africa, Asia and Latin America. The institute's work is currently divided into four main areas: natural resources, climate change, human settlements and sustainable markets.

IIED is based in central London on High Holborn and has an office in Edinburgh. It formerly had offices in Dakar, Senegal (now an independent organisation IED-Afrique) and Buenos Aires, Argentina (also an independent sister institution, IIED-America Latina). There was also an office in Washington DC, USA (until IIED North America merged with the World Resources Institute in 1988).

The International Institute of Environment and Development has more than 140 employees and researchers from 16 countries. The organisation's Board of Trustees are all volunteers, currently 11 representatives from 11 different countries. The working budget of the IIED, £18.2 million in 2020/21, is achieved through donations, grants and mutually beneficial partnerships.^[2]
