Union Minister Nitin Gadkari attributed air pollution to the use of fossil fuel and diesel. He acknowledged the traffic congestion in Delhi as a significant problem and stated that the government has undertaken projects worth Rs 65,000 crore to address it. The ongoing construction of the 30 km long Dwarka expressway, costing Rs 10,000 crore, is almost 80% complete and is one of the initiatives aimed at mitigating traffic-related issues in the national capital.
