Environment minister Gopal Rai stated that 36% of Delhi's pollution is due to vehicular pollution and 31% is caused by biomass burning. Despite a decrease in stubble burning incidents, the pollution level continues to rise. The city's air quality turned 'severe' with an AQI of 415. Measures have been taken to enforce GRAP-III guidelines and run special campaigns to prevent biomass burning. The transport department and Delhi Police have deployed teams to ensure compliance and a fine of Rs 20,000 will be imposed for violations under the Motor Vehicle Act-1988.
