Introduction of 41 electric buses in Cluj-Napoca, Romania determines that electric buses are a viable means of reducing emissions in urban areas.
Cluj-Napoca, Romania
Direct and Indirect Environmental Aspects of an Electric Bus Fleet Under Service
Summary Information
Urban pollution is an ongoing public health and environmental problem in many cities around the world. Electrification of vehicles may be one solution to this problem, particularly if heavy duty diesel vehicles like buses are electrified.
To help address air pollution issues, authorities in the city of Cluj-Napoca, Romania replaced 41 diesel buses with electric buses. A team of scientists from Cluj-Napoca Technical University then estimated both the direct and indirect emissions reductions from this replacement. The team did this by first measuring direct emissions from traditional diesel buses and estimating the emissions off-set from replacing them with electric buses. The team then analyzed emissions off-sets when accounting for the electricity needed to charge the buses as well and the various sources of this electricity.
- The electric buses directly eliminated 668.45 tons of CO2 emissions and 6.41 tons of NOx emissions.
- When accounting for electricity emissions, the electric buses eliminated 509.95 net tons of CO2 and 5.62 net tons of NOx.
