Union Government releases  a new four-colour classification scheme for industries based on their pollution potential

Union Government has released a new four-colour classification scheme for industries based on their pollution potential. The four-colour classification scheme of industrial sectors based on the Pollution Index (PI) . Pollution Index  is a function of the
(i) Emissions (air pollutants)
(ii) Effluents (water pollutants)
(iii) hazardous wastes generated and
(iv) Consumption of resources.

Under the new categorisation system, industries which pollute the most have been put in the red category while the moderately polluting units are classified in orange category.
Industries that have a significantly low
polluton load have been placed in the green category while those that operate without causing any pollution have been categorised in white category.

Environmental Impact Assessment (EIA) compares various alternatives for a project and seeks to identify the one which represents the best combination of economic and environmental costs and benefits. Eight steps of EIA involves screening, scoping impact analysis,mitigation,reporting,review,decision making and post monitoring.
