New Delhi has activated Stage 1 of the Graded Response Action Plan (GRAP-1) as its air quality index (AQI) has fallen into the 201 to 300 range, categorised as 'poor'. This move initiates a series of emergency measures designed to prevent further deterioration of air quality once it crosses a critical threshold, safeguarding public health in the densely populated capital.

GRAP is a comprehensive framework of anti-pollution measures that are incrementally enforced in the National Capital Region. Its primary purpose is to introduce timely interventions to mitigate the build-up of atmospheric pollutants. The activation of GRAP-1 signifies that while the air quality is concerning, it has not yet reached the more severe 'very poor' or 'severe' categories, which would trigger more stringent restrictions. The current measures are a proactive step to manage the existing pollution levels and avert a more critical environmental situation.

Among the immediate restrictions imposed under GRAP-1 is a prohibition on the use of tandoors in eateries and restaurants across the city. This particular measure targets emissions from commercial cooking operations, which can contribute significantly to particulate matter in the local atmosphere. By curtailing the use of these traditional clay ovens, authorities aim to reduce one source of airborne pollutants that directly impacts ambient air quality.

Furthermore, the open burning of waste materials has been strictly forbidden throughout Delhi. This common practice, often observed in various parts of the city, releases a hazardous mix of gases and fine particulate matter into the air. Eliminating open waste burning is a fundamental step in controlling ground-level pollution and is a recurring focus of environmental regulations during periods of poor air quality.

In an effort to curb vehicular emissions, a major contributor to urban air pollution, parking charges across the capital have been doubled. This economic disincentive aims to discourage the use of private vehicles and encourage residents to opt for public transportation. By reducing the number of cars on the roads, the measure seeks to alleviate traffic congestion and consequently lower the overall emission of harmful gases and particulate matter from vehicle exhausts.

These emergency protocols are crucial for managing pollution spikes and maintaining air quality within acceptable, albeit still challenging, parameters for Delhi's inhabitants. The structured approach of GRAP allows for a graded response, ensuring that measures are proportionate to the prevailing air quality conditions and are scaled up or down as the situation evolves. The implementation of GRAP-1 underscores the persistent environmental challenges faced by Delhi and highlights the continuous efforts required to manage and improve the city's air quality for its millions of residents.
