Alba discusses air pollution issues in her city of Delhi, India. She notes that air pollution has caused many health problems and that buses, taxis, and auto-rickshaws contribute significantly to pollution levels. However, between 2001 and 2010, sulfur dioxide levels dropped due to improvements like switching vehicles to compressed natural gas, expanding public transportation like metro networks, and banning trucks during certain hours. These measures helped address the pollution problems caused by heavy traffic in the city.

on diesel to compressed natural gas; a successful
metro network has been rolled out; a ban on
