Road transportation is one of the biggest sources of air pollution throughout the world. After liberalization and globalization, India has witnessed a gigantic growth in number of road vehicles. It eventually resulted in surging release of greenhouse gases, mainly CO2. In this paper, the emission of greenhouse gases (CO2, CO, NOx, CH4, SO2, PM and HC) from road transportation in 7 million plus cities in Uttar Pradesh, namely Agra, Allahabad, Ghaziabad, Kanpur, Lucknow, Meerut and Varanasi, has been calculated from 2010-2019. The emission has been estimated based on number of registered vehicles, their annual utilization and corresponding emission factors. The emission from road transportation in selected cities has grown enormously in this decade. Allahabad has shown the largest growth in CO2 emission (131.15%), while the lowest growth has been seen in Agra (30.3%). Lucknow has been the largest emitter of CO throughout the decade, contributing 5.85% (2019) of total CO emissions from road transportation in Uttar Pradesh. Pollution load in terms of CO2 emission (2019) is highest in Varanasi (14.5 Gg/km2), which is about 58 times higher than the state average (0.25 gg/km2).
