Summary
This 2022 life cycle assessment evaluated the environmental profile of electrifying urban public transport bus fleets as part of broader sustainable urban development strategies. The study appears to have applied standardised LCA methodology to compare electric and conventional bus systems across their full lifecycle—from manufacturing through operation to end-of-life—to inform policy decisions on urban transport electrification. The findings contribute to understanding whether electric bus adoption delivers net environmental benefits when upstream manufacturing and electricity generation impacts are accounted for.
UK applicability
The findings may be broadly relevant to UK local authorities and transport authorities considering bus fleet electrification as part of net-zero commitments, though results will depend on the electricity grid carbon intensity assumed in the Polish study versus current and projected UK grid mix. UK applicability would be strengthened if the study addresses the specific emissions profile of UK electricity generation and vehicle manufacturing contexts.
Key measures
Lifecycle greenhouse gas emissions, energy consumption, resource use, environmental impact categories (as suggested by LCA methodology)
Outcomes reported
The study quantified environmental impacts of transitioning urban public transport bus fleets from conventional to electric propulsion using life cycle assessment methodology. The analysis evaluated greenhouse gas emissions, resource consumption, and other environmental burdens across the full lifecycle of electric versus conventional buses.
