Purpose – Kolkata’s motor vehicle fleet has grown rapidly in recent years resulting in consequent increase in energy consumption and pollution by the transport sector. The number of registered vehicles in the city increased from 14.42 lakhs in 2013 to 23.17 lakhs in 20221 . Energy transition in the sector including adoption of environment friendly energy efficient technologies and measures is urgently required in Kolkata. One of such options of electric vehicles (EV) is a viable and cleaner way offering large potential for fuel savings and curbing pollution from the sector. However, new technologies do not get adopted on their own; they need to be pushed and facilitated by various drivers. This research aims to examine the different factors that are key to a faster uptake of energy efficient option like EV and lead to energy transition in Kolkata’s transport sector.
