Pollution

Integrating waste minimisation, climber accountability and community engagement is seen as critical to safeguarding fragile ecosystems while preserving access for future generations.

The transition of the ‘No PUC, No Fuel’ policy from a seasonal anti-pollution measure to a permanent, year-round mandate marks one of the most ambitious steps taken by the Delhi government in its fight against vehicular emissions.

Critics from environmental organisations and civil society have described the current legal interpretation as a “simplification that fails to respect the Aravallis’ complex ecology”, warning that it could gradually weaken the shield that the mountain system provides against desertification, water scarcity, and biodiversity loss.

While official forecasts have suggested potential weather shifts that could help disperse pollutants, scientists caution that air quality may remain poor in the coming days without sustained reductions in emissions.

Despite short-term improvements when winds disperse pollutants, Pakistan’s larger “smog season,” which typically lasts from October through February, has become a recurring annual crisis with economic and social costs that reverberate beyond public health into education, productivity and infrastructure planning.

The dual pressure – aggressive regulation of both ground-level dust and industrial emissions – makes clear: this winter, Delhi’s fight for breathable air will be fought on multiple fronts.

The evidence from the study is unequivocal, researchers point out: air pollution is a direct threat to children’s intellectual growth, disproportionately affecting the vulnerable.

Public health advisories issued on days like these typically urge people to stay indoors unless absolutely necessary, reduce outdoor activities, keep windows closed, and use air purifiers where possible. But for many living in low-income neighbourhoods without access to such safeguards, these recommendations offer little relief.
