Heavy goods vehicles keep cities running. Supermarket shelves, building sites and high street shops all depend on them. But busy delivery routes also pass homes, schools and workplaces, putting freight transport at the centre of the urban air quality conversation.
Replacing diesel trucks takes more than buying new vehicles. Fleets also need reliable electric truck charging stations, with sufficient electrical capacity and charging schedules that fit around daily deliveries. Vehicles and infrastructure need to be planned together if electrification is to translate into cleaner streets.
What HGVs actually contribute
Heavy goods vehicles are a significant source of transport emissions. Department for Transport figures show that HGVs produced 18.2 million tonnes of carbon dioxide equivalent in 2023, accounting for 16% of the UK’s domestic transport greenhouse gas emissions. That figure describes their climate impact, rather than their share of local air pollution.
The distinction matters. Carbon dioxide contributes to climate change, while nitrogen oxides and particulate matter damage air quality. A fleet can improve on one measure without solving the other.
Diesel vehicles have become cleaner over time. Official figures show that UK HGV nitrogen oxide emissions fell by 93% between 1990 and 2023. That is substantial progress, although a cleaner combustion engine still produces exhaust emissions where it operates.
What changes when a truck is electric
A battery electric truck has no tailpipe emissions. It does not release exhaust nitrogen oxides or exhaust particles outside a school, beside a pavement or while waiting at a loading bay. For people living and working along busy freight routes, removing that local source of pollution is a practical benefit.
Electric drivetrains can also make low-speed operation quieter. That is particularly relevant to early morning deliveries and refuse collection near homes, although tyres, loading equipment and the handling of bins or goods still create noise.
Climate benefits need a wider assessment. Electricity generation, battery production, vehicle manufacture and lifetime use all belong in the calculation. An annual carbon-saving estimate for one truck cannot simply be applied to every fleet: mileage, payload, energy consumption and the electricity supply change the result.
Electrification also leaves some pollution sources in place. Tyres and road surfaces still wear, and friction brakes can still release particles. Regenerative braking can reduce reliance on those brakes, but it does not make a heavy vehicle free of non-exhaust emissions. Nor does changing the powertrain remove congestion.
Why charging infrastructure matters
A truck earns its place in a fleet by completing its work reliably. Charging therefore has to fit the route, rather than becoming a daily obstacle to it.
For vehicles that return to base, depot charging can use the hours when trucks would already be parked. Longer routes or closely spaced shifts may require charging at destinations or along the journey. Charger location, vehicle access and the time available to replenish the battery all matter.
Planning should begin with a few concrete questions: how much energy does each route require, when do vehicles return, how much power is available on site, and what happens if a charger fails? A high headline charging rate is useful only when the vehicle, electrical connection and operating schedule can take advantage of it.
Consider a delivery truck that spends the night at its depot. Its charging needs may be very different from those of a vehicle returning briefly between two long shifts. Buying the same charging equipment for both without examining their schedules risks unnecessary cost or inadequate capacity.
Where cities can see practical gains
Regular urban routes are useful places to assess electrification because their distances, stopping patterns and return times can be measured. Refuse collection and local distribution are clear examples. Construction deliveries and port-to-city journeys may also offer opportunities, depending on payloads, route length and charging access.
Westminster provides a real example of planning vehicles and infrastructure together. The council announced investment in 45 electric refuse trucks alongside a depot designed to charge 54 vehicles simultaneously. Its stated aims included cutting air pollution and reducing vehicle noise for residents.
Freight decarbonisation also extends beyond the truck itself. As our article on the carbon cost of cold chain logistics explains, the supporting systems around a delivery can carry their own energy demands. Fleet planning needs to consider the complete job a vehicle performs.
Support needs to be checked against current rules
UK support includes the Depot Charging Scheme and grants for eligible zero-emission vehicles. Operators should check the official guidance before committing expenditure, because application windows, funding rates and eligibility conditions can change.
As checked on 15 October 2026, the official Depot Charging Scheme page said applications were closed, with a further window expected to open on 28 October 2026. Terms and grant rates for that next phase had not yet been confirmed. An expected funding opportunity should not be treated as an approved award.
What this means for cities
Electric trucks can remove exhaust pollution from the streets they serve, but they work best as part of a broader freight strategy. Better loading, fewer empty journeys and shifting suitable longer-distance freight to rail all deserve attention. Our look at rail transport and the footprint of food explores one part of that wider picture.
The useful question is not simply whether a city has more electric trucks. It is whether those vehicles reliably replace diesel work, have charging that suits their routes, and reduce pollution where people are exposed to it. Infrastructure turns the purchase of a cleaner vehicle into a service that can run day after day.
