The Department of Science, Technology and Environment was started in 1993 after merging of the erstwhile Science & Technology and Environment cells functioning in the U.T. Administration. The DSTE is the nodal agency for planning, promotion, co-ordination and overseeing the implementation of environmental policies, technology and programmes. The Department designs and implements policies and programmes to preserve, conserve and protection of Environment. The primary concerns of the department are implementation of policies and programmes relating to conservation of the natural resources, biodiversity and environment, and the prevention and abatement of pollution. While implementing these policies and programmes, the department is guiding for sustainable development and enhancement of human well-being.
