Sustainable Urban Mobility Transition in Pakistan: Environmental and Economic Evidence from Motorcycle Electrification in Islamabad

Abstract

Urban transport systems in Pakistan are increasingly characterized by high motorcycle dependence, contributing to rising greenhouse gas emissions and urban air pollution. This study provides empirical evidence on the environmental and economic implications of motorcycle electrification within the framework of sustainable urban mobility transition. Using 2023 fleet data from Islamabad, emission factor analysis and lifecycle cost modeling were conducted to assess the impact of replacing internal combustion engine motorcycles with electric alternatives. The results indicate that full electrification of the existing motorcycle fleet could eliminate more than 128,000 tons of carbon dioxide annually at the metropolitan level, alongside the removal of nitrogen oxide emissions from tailpipe sources. Economic analysis demonstrates that although electric motorcycles involve higher initial purchase costs, lower fuel and maintenance expenditures generate long-term cost advantages for households. The projected additional electricity demand represents a manageable share of national generation capacity, suggesting technical feasibility under current infrastructure conditions. While electrification offers substantial climate and economic co-benefits, implementation requires coordinated governance mechanisms, affordability support, and integration with ongoing energy sector reforms. The findings support Pakistan’s commitments under Sustainable Development Goals 7, 11, and 13 and position motorcycle electrification as a scalable pathway for sustainable urban mobility transition.
