Delhi Metro: Double the Size for Cleaner Air?

Delhi's Metro network may need to more than double its current operational length to effectively tackle vehicular pollution. A recent recommendation from the Commission for Air Quality Management (CAQM) suggests an expansion to approximately 900 km, drawing a comparison to Beijing's existing 879 km Metro system. This ambitious proposal aims to significantly increase the daily ridership, currently serving 6.5 to 7 million passengers.

The CAQM's recommendation emphasizes the need for strengthening last-mile connectivity and an integrated transport plan to combat air pollution, a major contributor to the Capital's poor air quality. While the Delhi Metro currently has a network of 462.7 km, with ongoing construction, officials note that expanding to 900 km presents significant logistical and space challenges, potentially exceeding planned expansions up to 600 km.

Experts suggest that while Metro expansion is beneficial, enhancing feeder services, improving walkability, and creating cycling tracks are also crucial. Studies indicate a correlation between Metro network expansion and health benefits, including reduced air pollution exposure. The Delhi government is also increasing its bus fleet, aiming for 14,000 buses by March 2029 to bolster public transport.
