Sensitivity in the operation of conventional and alternatively fuelled public service vehicles on Merseyside

摘要: This paper compares the sensitivity in operation of conventional and alternatively fuelled Public Service Vehicles (PSVs) across Merseyside. Each fuel is compared on a life cycle assessment (LCA) basis, with addition landfill gas (LFG) as viable alternative. On complete LFG powered vehicles compare favourably gas-powered generally cause less pollution than liquid-fuel vehicles, electric producing least overall. In majority cases, analysis has revealed that most significant stage cycles each vehicle end-use (fuel combustion) stage. some cases this alone contributes to 90% total emissions. Daily annual changes have large influence amount released into atmosphere.
