The Environmental Information System acronymed as ENVIS was implemented by the Ministry by the end of 6th Five Year Plan as a Plan Scheme for environmental information collection, collation, storage, retrieval and dissemination to policy planners, decision makers, scientists and environmentalists, researchers, academicians and other stakeholders.

            ENVIS is a decentralized computerized network database system consisting of the focal point located in the Ministry and a chain of network partners, known as ENVIS Centres located in the potential organizations/institutions throughout the country.

            In order to develop ENVIS network as a comprehensive distributed environmental information network system, the ambit of ENVIS was extended to cover all the States/UTs of the country. Necessary guidelines and policies were provided to revise the earlier EFC of the scheme and the new concept for covering the State Government departments were completed through a revised SFC.

            Presently, the ENVIS network consist of 76 ENVIS centres link to apart from the focal point located in the Ministry, out of which, 30 Centres are on State Government Departments dealing with the Status of Environment and related issues of the concerned State Government and the remaining 46 have been set up on various environmental disciplines covering from air pollution, water pollution, noise pollution, biodiversity, solid waste management, ecology and ecosystems, environmental education, NGOs, media and even environmental parliament, coastal ecosystem, clean technology, etc.

            Both the Focal Point and ENVIS Centres in their assigned subject-areas are developing the requisite databases on identified parameters in order to disseminate information concerning their subject-areas to the user concerned. In order to disseminate information online almost all the ENVIS Centres have developed their interactive databases in their assigned subject-areas for requisite dissemination. The ENVIS Focal Point has also developed a comprehensive interactive website for online coordination with all its network partners as well as dissemination of information to the users whenever required.

            The focal point of ENVIS has developed a comprehensive database with GIS interface known as Indian State Level Basic Environmental Information Database (ISBEID) on 17 modules in various subject areas of environment and its associated fields which are quite relevant to the State ENVIS Centres. This will assist the State ENVIS Centres to produce the State of Environment report for he concerned states/UTs,
