IEA HEV Task 46 (LCA of Electric Trucks, Buses, Two-wheelers and other Vehicles) was organizing an online expert workshop in collaboration with AMF Task 64 (E-fuels and End-use perspectives) on

Environmental Impacts of Buses - Aspects of Climate Neutrality and Circularity

The aim of this online expert workshop (hosted by JOANNEUM RESEARCH) was to analyse, assess and discuss the environmental effects of buses with different propulsion systems based on LCA.

The format of the workshop was based on presentations, discussions, and interactive group work. Here are some of the findings from the workshop:

• Electric buses have lower greenhouse gas emissions and primary energy demand if renewable electricity is used compared to H2-fuel cell, internal combustion engines (ICE) with e-fuels and ICE with diesel buses.
• Climate neutrality is only possible with Carbon Capture & Storage (CCS)
• Relative advantages in the life cycle assessment (LCA) of the battery-electric vehicles decrease with increasing vehicle (and battery) size.
• Currently the main focus of LCA is on greenhouse gas emissions and primary energy demand.
• improved data sets on the most important raw materials (virgin/primary and recycled/secondary) are needed to better determine the influence of raw materials on environmental impacts
