The Forest Principles (also Rio Forest Priciples) is the informal name given to the Non-Legally Binding Authoritative Statement of Principles for a Global Consensus on the Management, Conservation and Sustainable Development of All Types of Forests (1992), a document produced at the United Nations Conference on Environment and Development (UNCED), informally known as the Earth Summit. It is a non-legally binding document that makes several recommendations for conservation and sustainable development forestry.
At the Earth Summit, the negotiation of the document was complicated by demands by developing nations in the Group of 77 for increased foreign aid in order to pay for the setting aside of forest reserves. Developed nations resisted those demands, and the final document was a compromise.
The FOREST EUROPE process (Ministerial Conferences on the Protection of Forests in Europe, MCPFE) was started by Strasbourg Conference in 1990 and the Forest Principles were adopted and incorporated into the agenda by Helsinki Conference in 1993. The process covers Pan-European region consisting of 47 signatories (46 European countries and the European Union) that partially overlaps with Montreal Process region (Russia is a signatory of both processes).
The Montreal Process, also known as the Working Group on Criteria and Indicators for the Conservation and Sustainable Management of Temperate and Boreal Forests, was started in 1994 as a result of the Forest Principles.
