Delhi’s Air Quality Index (AQI) has once again slipped into the ‘Poor’ category after nearly a week of ‘Moderate’ air quality, aided by favorable meteorological conditions.

Stage 1 of GRAP, a set of winter-specific anti-pollution measures, focuses on dust mitigation at construction sites, proper waste management, and regular road cleaning.

It additionally bans open waste burning, restricts the use of diesel generators, and prohibits coal or firewood usage in eateries.
