Subramanium Committee Recommended Single Window System For Environment Projects: In the month of January 2015, High-level committee (HLC) headed by former Cabinet Secretary T S R Subramanium submitted its report to Union Government. In its recommendation, the committee suggested single window clearance mechanism for green nods.The committee has suggested an umbrella law to help set up new national and state-level regulators that would also take the powers of the existing pollution control boards. The law – Environmental Management Act – would do away with the need for separate Acts to regulate air and water pollution that empower states to give the consent to operate and establish industrial units.
