Mumbai registered an Air Quality Index reading of 164, while Delhi recorded an AQI of 165, placing both cities in India's moderate air quality category for that snapshot before Delhi's air quality later deteriorated further.
As Delhi's AQI entered the poor category, the Commission for Air Quality Management invoked Stage I of the Graded Response Action Plan across the National Capital Region with immediate effect. This included prohibitions on using coal and firewood in tandoors at eateries, restrictions on diesel generator sets, and strengthened dust-management controls.
The Brihanmumbai Municipal Corporation intensified action against violating construction sites by issuing stop-work notices and imposing financial penalties, such as a notice and penalty issued for a demolition site in Oshiwara. The civic body enforces a 28-point framework for dust and pollution control, placing construction projects under close scrutiny.
