The haulage industry plays a vital role in keeping goods moving across the UK and beyond. But this convenience comes at a cost. Transport is one of the biggest contributors to carbon emissions, and heavy goods vehicles (HGVs) are a major part of that picture.
As environmental concerns grow and regulations tighten, many haulage companies are being forced to rethink how they operate. In this article, we’ll look at the environmental impact of road haulage, what’s being done to address it, and where the industry is heading next.
| Key Facts About Emissions From HaulageRoad freight is responsible for a significant share of UK transport emissions. According to the Department for Transport (DfT):HGVs make up just 5% of vehicles on the roadBut they contribute around 20% of road transport CO₂ emissionsA single diesel lorry can emit over 1,300 grams of CO₂ per kilometreThere’s an obvious urgent need for change, especially as the UK aims to reach net zero by 2050. |
Haulage Has a Bigger Environmental Footprint Than You Might Think
Unlike passenger cars, HGVs often travel long distances with heavy loads, which requires more fuel. Many haulage routes include long periods of idling, waiting at depots, or navigating urban traffic, all of which increase emissions.
Most HGVs still run on diesel, a fuel that produces high levels of carbon dioxide, nitrogen oxides (NOx), and particulate matter. These pollutants not only contribute to climate change but also affect local air quality.
What Is the Industry Doing to Cut Emissions?
There’s no single solution, but haulage companies are exploring several approaches to reduce their impact:
- Switching to newer, cleaner vehicles that meet Euro 6 standards
- Training drivers to adopt fuel-efficient driving techniques
- Using route optimisation software to reduce unnecessary mileage
- Investing in fleet maintenance to ensure engines run efficiently
These practical steps are already helping some businesses lower their emissions and reduce fuel costs at the same time.

Electric and Alternative Fuel HGVs
Electric HGVs are beginning to enter the market, though adoption is still slow. Limited range, high upfront costs, and a lack of charging infrastructure are major hurdles. Still, manufacturers like Volvo and DAF are producing electric models, and trials are taking place across the UK.
Some operators are also experimenting with hydrogen fuel cell technology or using biofuels as a transitional step. These alternatives emit less CO₂ than diesel, but each comes with trade-offs around cost, availability, and infrastructure.
Diesel and Electric HGVs
| Aspect | Diesel HGVs | Electric / Zero-Emission HGVs |
| Fuel emissions | High CO₂, NOₓ, particulates | Zero tailpipe CO₂, NOₓ |
| Range | Long, well established | More limited, improving |
| Refueling time | Minutes | Longer (charging), though fast charging is improving |
| Maintenance | Mechanical complexity, engine servicing | Simpler drivetrain, lower maintenance |
| Infrastructure required | Fuel stations widespread | Charging/fueling network expansion needed |
| Upfront cost | Lower | Higher, offset by incentives or lower operational cost |
| Lifecycle emissions | Embedded manufacturing + fuel | Manufacturing emissions, battery lifecycle, electricity source |
Are Electric HGVs Ready for the Road?
Electric lorries work best for short-haul or regional routes where charging points are more accessible. For longer distances, battery range and charging time still present challenges.
That said, government-backed projects like the Zero Emission Road Freight programme are helping test and scale these solutions. If infrastructure investment continues, electric HGVs could become a much more practical option within the next five to ten years.
New haulage rules every business should know
The UK government has announced plans to phase out new diesel HGVs by 2040. This is part of the wider Transport Decarbonisation Plan, which aims to make all forms of transport cleaner.
Low Emission Zones (LEZs) and Clean Air Zones (CAZs) are already active in cities like London, Birmingham, and Bristol. These areas charge older diesel lorries a fee to enter, which is pushing more operators to upgrade to cleaner vehicles.
There are also grants available for businesses that want to trial electric or hydrogen-powered lorries. These include support through schemes like Innovate UK and the Office for Zero Emission Vehicles.
Benefits of Reducing Emissions in Haulage
While the environmental benefits are clear, there are business advantages too. Reducing emissions often means reducing fuel use, which can cut costs significantly. Cleaner vehicles may also have lower maintenance needs and avoid LEZ or CAZ charges.
Here are a few practical outcomes:
- Improved air quality in towns and cities
- Lower carbon footprint per delivery
- Enhanced reputation among eco-conscious clients
- Better compliance with evolving environmental regulations
Public Perception and Client Expectations
Customers are increasingly looking to work with companies that demonstrate environmental responsibility. Some larger clients now require proof of sustainability credentials before awarding contracts.
Having a plan in place to reduce your emissions is not only good for the planet, it can also help you win business. It shows you’re thinking ahead and taking the issue seriously.

What Needs to Happen Next?
For the haulage sector to reduce emissions on a large scale, three things need to improve:
- Infrastructure — More charging stations and hydrogen refuelling points
- Vehicle options — A wider range of affordable electric or alternative-fuel HGVs
- Government support — Clear policy and funding for transition costs
Until those are addressed, many businesses will continue relying on diesel. But awareness is growing, and the direction of travel is clear.

Common Questions in Haulage Decarbonisation
How far can electric HGVs go compared to diesel?
Range remains a limiting factor. Current electric trucks are more feasible for short to medium distance routes (say up to 200–300 km) rather than cross-country hauls. Battery weight and charging time still restrict long-haul use cases.
As battery technology improves and charging infrastructure expands, those limitations will gradually shrink.
Are hydrogen or fuel cell trucks a better alternative?
Hydrogen fuel cell trucks offer some advantages: faster refueling, lighter tanks relative to energy storage, and longer range potential. However, hydrogen production, infrastructure, and cost remain barriers. Their role might emerge in heavy duty and long-range segments complementing battery trucks.
What about the cost? Are zero-emission trucks more expensive?
Yes, upfront they cost more. But total cost of ownership (TCO) models show that over time with lower energy costs, maintenance, and incentives, zero-emission trucks can become competitive. One recent modelling suggests zero-emission trucks could reach cost parity as battery and fuel cell tech advance.
Will older freight fleets become obsolete?
Older fleets will likely retire or be repurposed over time. Some may operate in restricted zones, or be phased out by regulation (carbon taxes, low or zero-emission zones). Fleets that adapt early may avoid penalties or stranded assets.
How much difference can electrifying haulage make?
If a large share of HGVs switched to zero-emission, the potential reduction in transport sector emissions is significant. Given that HGVs account for around 20% of transport CO₂ emissions, electrification could shift the sector meaningfully toward net zero.
Some studies even equate removing HGV emissions to taking millions of cars off the road in terms of carbon impact.
