After weeks of severe pollution levels, Delhi witnesses a notable improvement in air quality, prompting officials to consider relaxing stringent measures under GRAP IV

Delhi breathed a little easier today as the city’s Air Quality Index (AQI) showed significant improvement, moving out of the “severe” category for the first time in weeks. This positive development has brought discussions on easing the Graded Response Action Plan (GRAP) IV measures to the forefront.

GRAP IV, the most stringent phase of the action plan, is invoked during hazardous pollution levels and includes restrictions on construction, industrial activities, and non-essential vehicular movement. The air quality has been a pressing concern in the national capital due to a combination of vehicular emissions, industrial activity, and seasonal stubble burning in neighbouring states.

Data from the Central Pollution Control Board (CPCB) revealed that the overall AQI in Delhi stood at 320 as of this morning, categorising it under the “very poor” range rather than “severe.” Officials attribute the improvement to favourable meteorological conditions, including stronger surface winds that have dispersed pollutants.

The Environment Pollution (Prevention and Control) Authority (EPCA) is scheduled to meet later today to assess the situation. Sources indicate that the relaxation of GRAP IV measures is a strong possibility, especially as forecasts predict further improvement in air quality over the coming days. However, some restrictions may remain in place to ensure that pollution levels do not spike again.

Environmentalists have lauded the improved air quality but cautioned against complacency. “While this is a step in the right direction, it’s essential to focus on sustainable long-term measures to combat pollution rather than relying solely on emergency responses,” said Anumita Roychowdhury, an environmental policy expert.

Delhiites, meanwhile, expressed relief at the respite from the choking smog. Residents noted clearer skies and a reduction in the lingering smell of pollutants that had plagued the city in recent weeks.

The GRAP, introduced by the Supreme Court-appointed EPCA, is a tiered action plan designed to mitigate pollution levels in Delhi-NCR. While it has been effective in managing immediate crises, experts argue that a comprehensive approach targeting the root causes of pollution is essential for sustainable improvement.

The ongoing discussions today are expected to provide clarity on the steps forward, balancing the city’s need for economic activity with the imperative to safeguard public health.
