The ENVIS Centre has been assigned the responsibility for serving as the focal point for information on NGOs related to sustainable development across the country. Over the past years, users both within and outside the country have come to recognize the Centre as a reliable and responsive source of environment-related information on NGOs. The Centre is currently compiling and updating information related to key NGOs in the country which promote sustainable development activities.

Over 2000 NGOs are listed in the Centre’s database on environmental NGOs. This database includes NGOs working on environment, nature protection and sustainable development in various parts of the country. This is the country’s largest compendium of information on Indian NGOs working in the fields of environment, sustainable development and nature conservation. The last published edition of the directory of Environmental NGOs in the country (2004) carried nearly 2018 entries with their contact numbers, histories, missions, and activities. The Directory remains a source of easy and reliable information for voluntary groups, government agencies, reference libraries, researchers, aid agencies, the media, and educational institutions.
