More balanced pathway for zero-emission trucks needed

Zero-emission HGV adoption falls to 0.9% despite £1 billion government funding

New data reveals a stark picture for the UK freight sector. Zero-emission vehicles now account for just 0.9% of new heavy goods vehicle registrations, according to figures from the Society of Motor Manufacturers and Traders. This represents a sharp decline from previous periods and raises serious questions about the viability of current policy timelines.

The government has committed £1 billion in grants to accelerate uptake. Individual operators can claim up to £81,000 per heavy zero-emission truck, covering 40% of purchase costs. Depot charging infrastructure attracts grants of up to £1 million. Despite this financial support, announced in March 2026, fleet operators remain cautious.

Heavy goods vehicles carry 89% of goods in the UK by weight. However, they also contribute 20% of domestic transport carbon emissions. Decarbonising this sector is therefore essential for meeting national climate targets. The challenge lies in balancing environmental urgency with commercial reality.

Government backs 350 zero-emission trucks through ZEHID demonstration programme

The Zero Emission Heavy Duty Vehicle and Infrastructure Demonstrator programme represents the largest public investment in zero-emission freight to date. Backed by £200 million from the Department for Transport and Innovate UK, ZEHID aims to deploy 350 battery-electric and hydrogen fuel-cell trucks by 2030.

The programme also funds installation of charging and refuelling infrastructure at over 70 sites nationwide. These include public locations and private depot facilities. Procurement and infrastructure installation will run from 2024 to 2026. On-road demonstrations will then continue from 2026 through 2031.

Each zero-emission HGV deployed through the programme can offset carbon emissions equivalent to dozens of passenger cars over its operational life. This demonstrates the disproportionate impact of decarbonising freight compared to focusing solely on private vehicles.

A government spokesperson stated that decarbonising freight is key to bringing down emissions from transport. The ZEHID programme specifically supports the industry with this transition. Nevertheless, the gap between ambition and adoption remains substantial.

Proposed 2040 ban on diesel HGVs faces implementation challenges

The UK government has proposed banning sales of new non-zero-emission HGVs by 2040. This timeline mirrors restrictions already introduced for cars and vans. However, the commercial vehicle sector faces distinct obstacles that passenger vehicle policies do not address.

Upfront costs remain the primary barrier. Zero-emission trucks typically cost two to three times more than diesel equivalents. Furthermore, total cost of ownership calculations depend heavily on utilisation patterns, energy prices, and maintenance costs that remain uncertain for newer technologies.

Infrastructure gaps compound these concerns. Public charging networks suitable for HGVs are limited. Depot charging requires significant electrical grid upgrades that many sites cannot accommodate without substantial investment. Hydrogen refuelling infrastructure barely exists outside demonstration projects.

Operational uncertainties also deter investment. Range limitations affect route planning. Charging times impact productivity. Cold weather performance remains inconsistent. Residual values are unknown. Consequently, many operators are extending the life of existing diesel fleets rather than committing to zero-emission technology.

The 0.9% adoption rate reflects these combined pressures. Fleet operators are choosing efficiency improvements for existing diesel vehicles over wholesale technology change. This approach reduces emissions incrementally but will not deliver the transformation required to meet 2040 deadlines.

California achieves one-in-six zero-emission truck sales through dual regulatory approach

California provides an informative contrast. In 2023, zero-emission vehicles accounted for one in six new truck sales in the state. This figure represents a doubling from previous years and demonstrates that rapid adoption is possible under the right conditions.

California’s success stems from paired supply and demand regulations. The Advanced Clean Trucks rule requires manufacturers to sell increasing percentages of zero-emission trucks. The Advanced Clean Fleets rule requires certain fleet operators to purchase them. This dual approach addresses both availability and market pull simultaneously.

However, even California experienced setbacks in 2025. Economic headwinds and political uncertainty caused a market reset. Commercial zero-emission vehicle deployments slowed. Delays have persisted into 2026, illustrating that momentum remains fragile even in the most mature markets.

California aims for 100% zero-emission heavy-duty vehicle operations by 2045 where feasible. This target comes with important caveats about technological and operational feasibility. The UK’s 2040 ban on new sales is more absolute but currently lacks the supporting regulatory framework that California has built over years.

US fleet operators demonstrate practical applications in transit and logistics sectors

Real-world deployments in the United States show where zero-emission technology is working today. In March 2026, El Paso’s Sun Metro introduced 45 zero-emission vehicles for paratransit services. These battery-electric buses provide accessible transport while eliminating local emissions in residential areas.

Logistics applications are also advancing. Hight Logistics began operating Tesla Semi trucks in commercial freight operations during 2026. Medium-duty battery-electric vehicles have found particular success in final-mile delivery and yard operations where routes are predictable and charging infrastructure is centralized.

Class 8 long-haul applications remain challenging. Range requirements often exceed current battery capabilities. Charging times are incompatible with driver hours regulations and delivery schedules. Weight penalties reduce payload capacity. These factors explain why long-haul adoption lags behind urban and regional applications.

A Zero-Emission Vehicle Workshop held in Dallas-Fort Worth on 21 April 2026 brought together fleet operators, manufacturers, and infrastructure providers. Discussions focused on practical barriers and solutions for medium and heavy-duty vehicles. Such collaboration is essential for identifying viable pathways forward.

Essential information for UK fleet operators and logistics businesses

• Zero-emission vehicles represented just 0.9% of new HGV registrations in the latest SMMT data, down sharply from previous periods.
• The government’s £1 billion grant programme offers up to £81,000 per heavy zero-emission truck and £1 million for depot charging infrastructure.
• The ZEHID programme will deploy 350 battery-electric and hydrogen fuel-cell trucks alongside over 70 infrastructure sites by 2030.
• A proposed ban on new non-zero-emission HGV sales takes effect in 2040, giving operators 14 years to transition fleets.
• Heavy goods vehicles contribute 20% of domestic transport emissions despite representing a small fraction of total vehicles on UK roads.
• Infrastructure challenges include limited public charging networks, inadequate depot electrical capacity, and minimal hydrogen refuelling availability.
• Total cost of ownership for zero-emission trucks depends on utilisation, energy prices, maintenance costs, and residual values that remain uncertain.

Why incremental efficiency improvements are delaying wholesale fleet transformation

Many operators are choosing to upgrade existing diesel fleets rather than switch to zero-emission technology. Modern diesel engines achieve significantly better fuel economy than older models. Aerodynamic improvements, low-rolling-resistance tyres, and driver training programmes can cut emissions by 10-15% without capital investment in new vehicles.

This incremental approach makes commercial sense in the short term. It avoids the high upfront costs and operational uncertainties of zero-emission technology. However, it locks in continued fossil fuel dependency and makes the eventual transition more abrupt and difficult.

The ZEHID programme specifically aims to address this by demonstrating real-world performance. Participating operators will generate data on reliability, operating costs, and practical challenges. This information should help reduce uncertainty for the broader market. Nevertheless, demonstration projects alone cannot overcome fundamental infrastructure and cost barriers.

Supply chain considerations also matter. Many fleet operators serve clients with sustainability requirements. Public sector contracts increasingly include carbon reduction criteria. Therefore, operators face pressure from customers as well as regulators. Sustainable procurement requirements are becoming standard in both public and private sector tenders.

Access to charging infrastructure will ultimately determine adoption rates. Depot charging suits operators with predictable routes and overnight parking at owned facilities. Public charging networks are essential for long-haul and multi-drop operations. Currently, neither is adequate for widespread adoption.

Grid capacity represents an additional constraint. Installing high-power charging for multiple vehicles requires electrical infrastructure that many depots lack. Upgrading transformers and cable capacity can cost hundreds of thousands of pounds and requires lengthy approval processes from distribution network operators.

How current policy settings compare to effective international frameworks

The UK approach combines funding support with future sales restrictions. This differs from California’s model of paired supply and demand regulations. Manufacturers in California must produce zero-emission trucks. Fleet operators must buy them. This creates both push and pull in the market simultaneously.

The UK relies more heavily on financial incentives to create demand while allowing market forces to drive supply. This approach reduces regulatory burden but may prove insufficient to achieve the pace of change required. The 0.9% adoption rate suggests current incentives are not yet changing operator behaviour at scale.

European Union regulations take a different approach again. The EU is implementing CO2 standards for new heavy-duty vehicles that tighten progressively. Manufacturers can meet these through efficiency improvements or zero-emission vehicles. This technology-neutral approach avoids prescribing specific solutions while ensuring emission reductions.

Some industry voices argue for a more balanced pathway that acknowledges different technologies mature at different rates. Battery-electric vehicles work well for urban and regional operations today. Hydrogen fuel cells may suit long-haul applications better but remain at an earlier stage of commercial readiness. Hybrid technologies could serve as a bridge, particularly for operators with mixed duty cycles.

The government’s focus on both battery-electric and hydrogen through ZEHID reflects this technology diversity. However, supporting multiple pathways requires different infrastructure investments. This increases complexity and cost compared to focusing on a single technology.

Commercial implications for operators, suppliers, and public sector buyers

Fleet operators face difficult investment decisions with incomplete information. Committing to zero-emission technology today means accepting higher costs and operational constraints. Waiting risks falling behind regulatory timelines and customer requirements. Many are adopting a wait-and-see approach that contributes to low adoption rates.

Vehicle manufacturers are caught between limited demand and the need to develop new models. Low sales volumes make it difficult to achieve economies of scale that would reduce prices. High prices suppress demand. Breaking this cycle requires either substantial subsidies or regulatory mandates that guarantee minimum sales volumes.

Infrastructure providers face similar chicken-and-egg problems. Building charging networks is expensive without guaranteed utilisation. Operators won’t buy zero-emission vehicles without charging infrastructure. Public funding helps but cannot solve the coordination problem entirely.

Public sector buyers have an important role. Government fleets and local authority contracts can create anchor demand that justifies infrastructure investment. Procurement specifications that require or favour zero-emission vehicles can accelerate market development. However, public buyers also face budget constraints and value-for-money requirements that make higher-cost vehicles difficult to justify.

Supply chain pressures are increasing. Large manufacturers like Unilever and Tesco have set science-based targets that include Scope 3 emissions from logistics. This pushes requirements down the supply chain to hauliers and logistics providers. Carbon reporting obligations are becoming more sophisticated and cover supply chain emissions more comprehensively.

Skills and training needs are also emerging. Technicians require different capabilities to maintain electric and hydrogen vehicles compared to diesel. Drivers need training on range management and charging procedures. Depot managers must understand electricity demand management and tariff optimization. These human factors are often overlooked in policy discussions focused on hardware.

What businesses should consider when evaluating zero-emission transition options

Operators should start by analysing their specific duty cycles and operational patterns. Battery-electric vehicles suit predictable routes with opportunities for regular charging. Applications with high daily mileage, irregular schedules, or remote locations present more challenges. Understanding your operational profile is essential before evaluating technology options.

Total cost of ownership calculations should include fuel savings, maintenance differences, and potential resale values. Electric drivetrains have fewer moving parts and lower servicing costs. Electricity is typically cheaper than diesel per mile, though this depends on tariffs and how efficiently charging can be scheduled. However, higher purchase prices and uncertain residual values complicate the analysis.

Infrastructure requirements need careful assessment. Depot charging requires adequate electrical capacity, suitable parking layouts, and potentially significant capital investment. Understanding lead times for grid upgrades is critical, as these can extend to 18 months or more in some areas. Public charging options should be evaluated for routes that cannot rely on depot charging alone.

Grant funding can significantly improve business cases but adds complexity. Applications require detailed technical specifications and project planning. Timing is important, as funding rounds have limited budgets and close once allocated. Professional support can help navigate these processes, particularly for smaller operators without dedicated sustainability teams.

Businesses should also consider their competitive positioning. Early adoption can differentiate operators in sustainability-focused tenders. It builds expertise and relationships with new technology suppliers. However, it also carries higher risks and costs. Later adoption benefits from more mature technology and lower prices but risks falling behind competitors and regulatory timelines.

Collaboration opportunities exist through industry groups and regional partnerships. Shared infrastructure can reduce costs. Joint procurement can increase buying power. Industry bodies provide technical guidance and best practice examples. The ZEHID programme itself offers opportunities to learn from funded demonstrators without direct participation.

Businesses should also prepare for carbon reporting requirements that will increasingly cover transport emissions. Understanding your baseline emissions and tracking reductions will become essential for regulatory compliance and customer reporting. This data also helps evaluate the carbon impact of different technology choices.
