India acceded to the Kyoto Protocol in August 2002 and one of the objectives of acceding to the Kyoto Protocol was to fulfill prerequisites for implementation of Clean Development Mechanisms (CDM) in accordance with the national sustainable priorities. The Kyoto Protocol commits the developed countries, including economies in transition to reduce emissions of greenhouse gases by an average of 5.2 per cent below 1990 levels during 2008-12. A National CDM Authority was approved by the Cabinet in December 2003 and has since started functioning. Meeting of National Clean Development Mechanism (CDM) Authority was held periodically to consider the CDM Projects for grant of Host Country approval. Till 10 March 2006, the National CDM authority has approved 252 projects in various fields biomass based cogeneration. The Authority has so far approved many projects mainly in the field of Renewable Energy. Municipal Solid Waste, Hydrofluorocarbons (HFCs), Small Hydro and Energy Efficiency, etc. It is expected that implementation of these projects would help in attracting foreign investment as well access to more efficient technologies.
