Electric Buses in Cities, Driving Towards Cleaner Air and Lower CO2, 2018 report by Bloomberg New Energy Finance

Key findings in the report, Electric Buses in Cities: Driving Towards Cleaner Air and Lower CO2, authored by BNEF on behalf of the C40 Cities Climate Leadership Group, highlight e-buses’ competitiveness with conventional diesel and CNG fueled buses. 

Air quality is a growing concern in many urban environments and has direct health implications for residents. Tailpipe emissions from internal combustion engines are one of the major sources of harmful pollutants such as nitrogen oxides and particulates. Diesel engines in particular have very high nitrogen oxide emissions and yet these make up the majority of the global bus fleet.

As the world’s urban population continues to grow, identifying sustainable, cost effective transport options is becoming more critical. Electric vehicles – including electric buses – are one of the most promising ways of reducing harmful emissions and improving overall air quality in cities.

E-buses have much lower operating costs and can already be cheaper, on the basis of total cost of ownership, than conventional buses today. The TCO of all electric bus configurations that we modelled improves significantly in relation to diesel buses as the number of kilometers traveled annually increases. For example, a 110kWh battery e-bus coupled with the most expensive wireless charging reaches TCO parity with diesel bus at around 60,000km traveled per year (37,000 miles).This means that a bus with the smallest battery, even when coupled with the most expensive charging option, would be cheaper to run in a medium sized city, where buses travel on average 170km/day (106 miles).
