Environmental, Health, and Economic Co-Benefits Assessment of the Electrification of Public Transport in Delhi (India)

In this study, an HIA (Heath impact assessment) model is developed to study the health and economic impacts of the electrification of public transport in Delhi. Health impact functions are obtained from C-R (concentration-response) models developed on the basis of relative risk studies and other epidemiological research. Baseline data on the economic values of health impacts is obtained from the available studies. The intervention scenario is based on powering all DTC (Delhi Transport Corporation) buses by battery. The model results revealed a significant reduction of emission and related health and economic benefits. The expected reduction in annual mortality is estimated at 793 cases, which will be equivalent to annual savings of USD 515 M (million) as well as 0.491 million tons of reduction in CO2 emissions.
