Comprehensive LCA report from Ricardo on behalf of EC confirms environmental benefits of electrified powertrains

Green Car Congress

The comprehensive report assesses the lifecycle impacts of representative European light- and heavy-duty vehicle types (cars, vans, trucks, buses and coaches) with 65 generic vehicle/powertrain combinations across 7 vehicle types. Demonstrate that methodological treatments can significantly influence the overall comparisons (e.g.
