The Commission for Air Quality Management directed New Delhi authorities to enforce stage II of the Graded Response Action Plan (GRAP) with immediate effect.
Graded Response Action Plan (GRAP)
- In 2014, when a study by the WHO found that Delhi was the most polluted city in the world, panic spread in the Centre and the state government.
- Approved by the Supreme Court in 2016, the plan was formulated after several meetings that the Environment Pollution (Prevention and Control) Authority (EPCA) held with state government and experts.
- The result was a plan that institutionalized measures to be taken when air quality deteriorates.
- GRAP also works as an emergency measure.
- It includes strict measures such as a ban on the entry of heavy vehicles, the odd-even road rationing restrictions, and a halt of construction work – each of which is likely to be impractical at a time when the pandemic has exacted heavy economic costs and public transport has been seen as an infection risk.
How does it work?
- As such, the plan does not include action by various state governments to be taken throughout the year to tackle industrial, vehicular and combustion emissions.
- When the air quality shifts from poor to very poor, the measures listed under both sections have to be followed since the plan is incremental in nature.
- If air quality reaches the severe+ stage, GRAP talks about shutting down schools and implementing the odd-even road-space rationing scheme.
Measures taken under GRAP
1) Severe+ or Emergency
