How much ground-level ozone does transport produce from electric vehicle motors, pantographs and other electrical devices which can generate arcs (electrical discharges in air)?

Background

The reducing environmental impacts strategic priority is in recognition that there is an environmental aspect to all transport, and therefore almost all the work of DfT. Transport is the largest emitting sector of greenhouse gases in the UK, contributing 27% of domestic emissions in 2019. Our transport system must change to deliver the government’s Net Zero ambition and DfT will drive forwards that change through our longer-term green transport agenda. On decarbonisation specifically, we published our Transport decarbonisation plan (TDP) in July 2021, which sets out the steps we will take to deliver the necessary carbon reductions across every form of transport. Sustainability will be at the heart of levelling-up. People everywhere will feel the benefits – villages, towns, cities, and countryside will be cleaner, greener, healthier and more prosperous and pleasant environments in which to live and work
