The Supreme Court of India has ruled that the implementation of GRAP IV (Graded Response Action Plan) in Delhi should continue even if the Air Quality Index (AQI) improves. The court emphasized that the air quality situation in Delhi remains critical, and measures under GRAP IV should stay in place to safeguard public health.
Background:
Delhi’s air quality has been a persistent concern, particularly during the winter months, when pollution levels often reach hazardous levels. The AQI in the capital city frequently crosses the threshold for hazardous air quality, leading to health advisories and temporary measures like restrictions on construction, vehicular emissions, and industrial activities.
The GRAP is a set of emergency measures that are implemented when the AQI exceeds certain thresholds, with different levels of actions corresponding to the severity of pollution. GRAP IV is the most stringent response, implemented when the AQI reaches the “severe” category.
The issue came before the Supreme Court when there were calls to ease the restrictions imposed under GRAP IV following a temporary improvement in air quality. However, the court ruled that the measures should not be lifted prematurely.
Court’s Decision:
The Supreme Court, in its ruling, emphasized that the risk to public health posed by air pollution remains significant, even if the AQI shows temporary improvement. The court pointed out that pollution levels could spike again, and it is necessary to err on the side of caution.
The bench directed that the measures under GRAP IV should continue to be enforced until there is a sustained improvement in air quality over a more extended period. The decision reflects the court’s commitment to ensuring the protection of public health and tackling the severe pollution levels that Delhi experiences.
Implications:
- Public Health Protection:
The court’s ruling underscores the importance of taking a long-term view of air quality management. By maintaining the stringent measures, the court seeks to ensure that the people of Delhi are not exposed to harmful levels of pollution, which can lead to respiratory issues and other health problems. - Environmental Concerns:
The continuation of GRAP IV highlights the ongoing environmental challenges faced by Delhi. Despite periodic improvements in AQI, the city continues to grapple with high pollution levels, driven by vehicular emissions, industrial activities, stubble burning in neighboring states, and other factors. - Government and Policy Action:
The Supreme Court’s ruling also puts pressure on the Delhi government and surrounding states to take more concrete steps to address the root causes of pollution. Long-term solutions, such as transitioning to cleaner fuels, enhancing public transportation, and addressing crop residue burning, will be necessary to bring about lasting improvements in air quality.
Conclusion:
The Supreme Court’s decision to maintain GRAP IV even if the AQI temporarily improves highlights the critical nature of air pollution in Delhi. The court has prioritized public health and urged sustained efforts to combat air pollution. This ruling reinforces the need for continued vigilance and comprehensive measures to ensure that air quality in Delhi does not deteriorate to hazardous levels again.
