Explained: What is GRAP, Delhi-NCR’s action plan as air pollution increases?

12th October, 2020 Environment

Context: Starting October 15, some stricter measures to fight air pollution will come into force in Delhi and its neighboring National Capital Region (NCR) towns, as part of the Graded Response Action Plan (GRAP).

  • The action plan has been in effect for three years in Delhi and NCR.
  • Pollution control authorities will begin night patrolling to check for dust and industrial emissions, as well as the burning of waste.
  • Mechanized sweeping and frequent sprinkling of water on roads (to make the dust settle) have been directed
  • These measures are part of GRAP, which was formulated in 2016 and notified in 2017.

What is GRAP?

  • 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 representatives and experts.
  • GRAP works only as an emergency measure.
  • 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.
  • The plan is incremental in nature — therefore, when the air quality moves from ‘Poor’ to ‘Very Poor’, the measures listed under both sections have to be followed.
  • If air quality reaches the ‘Severe+’ stage, the response under GRAP includes extreme measures such as shutting down schools and implementing the odd-even road-space rationing scheme.
  • GRAP has been successful in doing two things—
    • creating a step-by-step plan for the entire Delhi-NCR region, and
    • Getting on board several agencies: all pollution control boards, industrial area authorities, municipal corporations, regional officials of the India Meteorological Department, and others.
  • The plan requires action and coordination among 13 different agencies in Delhi, Uttar Pradesh, Haryana and Rajasthan (NCR areas).
  • At the head of the table is the Environment Pollution and Control Authority (EPCA), mandated by the Supreme Court.
  • GRAP was notified in 2017 by the Centre and draws its authority from this notification.

Has GRAP helped?

  • The biggest success of GRAP has been in fixing accountability and deadlines.
  • For each action to be taken under a particular air quality category, executing agencies are clearly marked.
  • Coordination among as many as 13 agencies from four states is simplified to a degree because of the clear demarcation of responsibilities.
  • Three major policy decisions that can be credited to EPCA and GRAP are the closure of the thermal power plant at Badarpur, bringing BS-VI fuel to Delhi before the deadline set initially, and the ban on Pet coke as a fuel in Delhi-NCR.


  • It includes members from the Centre for Science and Environment.
  • It was constituted in 1998 by the Supreme Court.
  • The initial mandate of the body was to ensure that Delhi’s bus and auto fleet moves entirely to CNG — a mammoth task that played a crucial role in cleaning Delhi’s air in the late 2000s.
  • The body continues to monitor pollution, and assists the Supreme Court in several pollution-related matters.

What measures have been taken in other states?

  • One criticism of the EPCA as well as GRAP has been the focus on Delhi.
  • While other states have managed to delay several measures, citing lack of resources, Delhi has always been the first to have stringent measures enforced.
