Context
The (CAQM) has invoked Stage 2 of the (GRAP) in the National Capital Region (NCR) as Delhi's Air Quality Index (AQI) dropped to the 'Very Poor' category. The restrictions aim to curb pollution through targeted measures on vehicular movement, dust control, and the promotion of public transport during unfavourable meteorological conditions.
UPSC Perspectives
Environmental
The Air Quality Index (AQI) is a critical metric for understanding the severity of air pollution, categorized from 'Good' (0-50) to 'Severe Plus' (>450). The invocation of (GRAP) Stage 2 highlights the persistent issue of winter pollution in the NCR, exacerbated by temperature inversion (a meteorological phenomenon trapping cold, polluted air near the ground) and low wind speeds. The plan relies heavily on source-apportionment—targeting major polluters like vehicular emissions (specifically targeting older BS-III petrol and BS-IV diesel vehicles) and construction dust. The shift towards BS-VI emission standards and Electric Vehicles (EVs), which are exempted from these bans, reflects a structural policy shift toward cleaner mobility. For UPSC, understanding the specific triggers for each GRAP stage (e.g., Stage 1: AQI 201-300; Stage 4: >450) and the scientific reasons behind winter smog formation in Northern India is essential for both Prelims and Mains.
Governance
The (CAQM) was established via the , replacing the (EPCA). This statutory body was created to address the fragmented jurisdictional issues between Delhi, Haryana, Punjab, Uttar Pradesh, and Rajasthan regarding air pollution. Its ability to mandate actions across states—such as altering office timings or increasing parking fees—demonstrates a strong centralized approach to a regional environmental crisis, overriding the traditional state-level pollution control boards in specific matters. The implementation challenges of GRAP, however, often expose issues of state capacity, such as the enforcement of PUC certificates or managing the diversion of heavy traffic. Mains questions often explore the effectiveness of such specialized statutory bodies versus traditional federal structures in managing transboundary environmental issues.
Economic
Environmental regulations like GRAP have significant, though often necessary, economic trade-offs. The restriction on older commercial vehicles disrupts logistics and supply chains within the NCR, imposing immediate costs on businesses and daily wage earners dependent on transport. Conversely, increasing parking fees acts as a Pigouvian tax (a tax on market activities that generate negative externalities), designed to alter consumer behaviour by discouraging private vehicle use. The economic cost of air pollution itself is massive, impacting public health, reducing labour productivity, and increasing healthcare expenditure. The long-term economic strategy embedded in these regulations is to incentivize a transition to a greener economy, pushing investments towards public infrastructure (like the increasing trips) and the adoption of EVs and CNG vehicles.
