• Cooler temperatures and meteorological factors such as lower wind speeds have contributed to the spike in pollution. The Commission for Air Quality Management (CAQM) has implemented Stage 1 of the Graded Response Action Plan (GRAP), which includes measures like banning diesel generator sets and restricting inter-state buses to clean fuel options. Despite the worsening air quality, Delhi has recorded 214 clean-air days this year, the highest in a decade excluding the COVID-19 period.

Impact & Risks

The 'Poor' air quality poses health risks, especially for individuals with pre-existing respiratory or cardiovascular conditions. Cooler temperatures and reduced wind speeds exacerbate pollution levels, trapping pollutants closer to the ground. The implementation of GRAP Stage 1 aims to mitigate further deterioration, but the situation remains concerning as stubble burning and festive activities are expected to increase pollution in the coming weeks.
