Delhi Breathes Easier—For Now: GRAP-4 Restrictions Lifted Amid Air Quality Debate
Imagine a city where the air is so toxic, it feels like breathing through a dirty cloth. That was Delhi just a week ago, when the Graded Response Action Plan's (GRAP) most severe measures, GRAP-4, were enforced due to dangerously high pollution levels. But here's the twist: those restrictions have now been lifted, sparking both relief and controversy.
In a recent meeting, the GRAP sub-committee declared that Delhi's air quality has significantly improved. The Commission for Air Quality Management (CAQM) attributed this to high winds and favorable weather conditions, with the Air Quality Index (AQI) dropping to 271, categorized as 'poor' but a far cry from the 'severe-plus' levels that triggered GRAP-4. But here's where it gets controversial: despite this improvement, forecasts suggest a potential rebound in pollution due to slower winds in the coming days. So, is lifting GRAP-4 premature?
Under GRAP-4, older vehicles were banned, and schools shifted to hybrid learning modes. Now, these vehicles can return to the roads, and schools can resume normal operations. However, GRAP-1 to GRAP-3 measures remain in place, which activate based on AQI levels: GRAP-1 for 'Poor' (201-300), GRAP-2 for 'Very Poor' (301-400), and GRAP-3 for 'Severe' (401-450). And this is the part most people miss: Delhi's decision to allow only Bharat Stage (BS) 6 vehicles during GRAP-3 and GRAP-4 phases had kept 1.2 million older, more polluting vehicles out of the city. Environment Minister Manjinder Singh Sirsa emphasized that only BS-6 vehicles from outside Delhi will be permitted during these phases, a move aimed at curbing vehicular emissions—a major contributor to Delhi's toxic air, especially during winter when smog lingers close to the ground.
Experts estimate that vehicles account for up to 40% of particulate pollution in the National Capital Region (NCR), particularly in heavily trafficked areas. By restricting higher-emitting vehicles, authorities aim to reduce pollution and protect public health. Yet, the question remains: is this enough? With forecasts predicting a potential rise in AQI, should Delhi have waited longer before lifting GRAP-4? Or is this a balanced approach to managing both environmental and economic concerns?
What do you think? Is lifting GRAP-4 a step in the right direction, or a risky move? Share your thoughts in the comments—let’s spark a conversation about the future of Delhi’s air quality!
