(a) the scientific criteria and parameters taken into consideration by Indian Institute
of Technology (IIT), Delhi to finalise the list of cities/districts of the country under
Comprehensive Environmental Pollution Index (CEPI); and
(b) the procedure being followed by the Ministry to carry out an environmental assessment
of industrial clusters across the country based on CEPI?
MINISTER OF STATE (INDEPENDENT CHARGE) FOR ENVIRONMENT AND FORESTS (SHRI JAI RAM RAMESH)
(a) To compute the Comprehensive Environmental Pollution Index (CEPI), Indian Institute of
Technology (IIT), Delhi has adopted the algorithm of Source, Pathway and Receptor and various
parameters like pollutant concentration, exceedence factors, impact on human health and level
of exposure have been taken into consideration for the calculation of pollution indices for
air, water and land (ground water). After integrating the indices for various media, a
composite CEPI has been evolved.
(b) The Central Pollution Control Board (CPCB) in collaboration with IIT, Delhi has applied
the CEPI for environmental assessment of 88 Industrial Clusters across the country. 43 such
industrial clusters having CEPI greater than 70, on a scale of 0 to 100, have been identified
as critically polluted.
