Has GRAP IV Been Implemented in Delhi Amid Pollution Surge?
Table of Contents
Delhi-NCR is currently experiencing a severe air pollution crisis, with Air Quality Index (AQI) levels soaring past 600 in several areas. This has led to widespread concern and questions about the measures being taken to combat the deteriorating air quality.A key question on many residents’ minds is whether the most stringent stage of the Graded Response Action Plan (GRAP),Stage IV,has been implemented.
what is GRAP?
The Graded Response Action Plan (GRAP) is a set of measures implemented by the Commission for Air Quality Management (CAQM) in Delhi-NCR to tackle air pollution. It categorizes pollution levels into four stages: Stage I (poor), Stage II (Very Poor), Stage III (Severe), and Stage IV (Severe+).Each stage triggers a specific set of actions aimed at reducing pollution sources.

Understanding the Stages of GRAP
- Stage I (Poor – AQI 0-100): Focuses on preventative measures and early warnings.
- Stage II (Very Poor – AQI 101-200): Increases restrictions on polluting activities, such as construction and diesel generator use.
- Stage III (Severe – AQI 201-300): Further intensifies restrictions, including banning construction activities and industrial operations.
- Stage IV (Severe+ – AQI 301+): The most stringent stage, invoking measures like stopping entry of trucks into Delhi and potentially closing schools.
Current Status: Is GRAP IV in Effect?
As of November 19, 2023, GRAP Stage IV has not been implemented across Delhi-NCR. However, restrictions under Stage III are currently in place. Hindustan Times Report The CAQM is closely monitoring the situation and will decide on implementing Stage IV based on the prevailing and predicted air quality.
On November 17, 2023, the CAQM directed the implementation of Stage III measures, which include:
- Banning construction and demolition activities (except for essential projects).
- Closing down industrial operations using polluting fuels.
- Increasing the frequency of mechanised sweeping and water sprinkling.
- Strict enforcement against vehicle pollution.
Why Hasn’t GRAP IV Been Implemented Yet?
While AQI levels have reached severe+ levels in some areas, the CAQM is likely considering several factors before implementing Stage IV.These include:
- Weather Conditions: Wind speed and direction play a crucial role in dispersing pollutants. Favorable weather conditions can temporarily improve air quality.
- effectiveness of Stage III Measures: The CAQM is assessing whether the current restrictions under stage III are having a noticeable impact on pollution levels.
- Economic Impact: Implementing Stage IV has significant economic consequences, particularly for the transportation and construction sectors.
Key Takeaways
- Delhi-NCR is facing a severe air pollution crisis.
- GRAP is a four-stage plan to combat air pollution.
- Currently, GRAP Stage III is in effect, not Stage IV.
- The CAQM is monitoring the situation and will decide on Stage IV implementation based on various factors.
