Increasing population, industrial activities and developmental projects are adding more and more pollutants in environment day by day. In order to tackle the problem of depleting natural resources and increasing burden of environmental pollution, every nation has to adopt a well organised environmental policy and planning strategy. Since environment is a broad-ranging, multi-disciplinary subject, a comprehensive information system on environment would necessarily involve effective participation of concerned institutions/ organisations in the country that are actively engaged in work relating to different subject areas of environment. ENVIS has, therefore, developed itself with a network of such participating institutions/organisations for the programme to be meaningful. ENVIS since inception has been on providing environmental information to decision makers, policy planners, scientists and engineers, research workers, etc.

Due to its comprehensive network, ENVIS has been designed as the National Focal Point (NFP) for INFOTERRA, a global environmental information network of the United Nations Environment Programme (UNEP). In order to strengthen the information activities of the NFP, ENVIS was designated as the Regional Service Centre (RSC) of INFOTERRA of UNEP in 1985 for the South Asia Sub-Region countries.
