Pakistan is highly vulnerable to climate change. Pakistan consistently ranks among the top 10 countries worldwide most affected by climate change. The growing transport emissions are partly due to the increasing reliance on private vehicle modes for transportation. Pakistan has taken meaningful steps towards transport sector decarbonization; including steps to encourage EV adoption. The National Transport Policy (2018) of Pakistan highlights the importance of public transport and non-motorized transport; and multimodal integration. Pakistan has introduced mass transit systems (mostly bus rapid transit) in several key cities such as Karachi; Lahore; Islamabad-Rawalpindi; and Multan; and is in the process of expanding these systems. EV adoption has fallen well short of targets and currently stands at less than 1 percent across all segments. The biggest barrier to EV adoption in Pakistan is the higher acquisition costs relative to ICE vehicles. This applies across all priority vehicle segments – e-2/3Ws and e-buses. This proposal concerns e-buses.This assignment aims to develop a national-level market assessment for e-buses in Pakistan and to assist the Sindh province to develop an implementation ready roadmap specific to e-buses in public bus fleets. The implementation roadmap for Sindh shall include identification of policy; regulatory; and financial measures needed to accelerate e-bus adoption in urban and regional public bus sleets and an institution-specific action plan for their uptake in the coming years.
