Pakistan's vehicle fleet has grown from about 4.47 million in 1990 to over 39 million by 2025, a 770% increase that is worsening air pollution in major cities. Carbon dioxide emissions from the country rose from 13.8 million tonnes in 1990 to 43.6 million tonnes in 2023, with transport playing a significant role in urban centers. Lahore reported the highest transport share of CO2 emissions at 81.3%, followed by Islamabad and Rawalpindi at 53%, Peshawar at 51%, and Karachi at 33%. The study also highlights health impacts, citing an estimated seven-year reduction in average life expectancy due to polluted air. However, the report lacks methodological details and does not propose specific policy measures or implementation timelines. For readers tracking emissions or clean transport policy, the key takeaway is the scale of the vehicle-driven problem and the need for concrete action on fuel standards, public transit, and urban planning.
