Reducing Greenhouse Gas Emissions from Heavy-Duty Vehicles in Europe

Heavy-duty vehicles (HDVs) account for around 25% of CO₂ emissions from EU road transport. Since 2014, these emissions have risen yearly, except in 2020, when COVID-19 temporarily reduced activity.

To reach the goal of a climate-neutral EU, the transport sector must change quickly. This includes boosting energy efficiency, switching to low-emission vehicles, and moving freight to more efficient transport modes.

🚚 Transport Sector and Greenhouse Gas Emissions

Despite improvements in vehicle efficiency, emissions from HDVs have increased. The reason? A sharp rise in freight transport demand, which outpaces energy efficiency gains.

To reverse this trend, the EU needs:

• Cleaner vehicle and fuel technologies

• Modal shift to rail and public transport

• Stronger emissions performance standards

• Better logistics and smarter transport planning

📈 Key Insights from the EEA

• EU-wide GHG emissions have dropped over the last decade.

• But HDV emissions continue to rise—driven by growing freight demand.

• In 2020, emissions fell briefly due to the pandemic, not systemic change.

• Trucks produce 85% of HDV emissions; buses and coaches account for the rest.

🚛 Energy Efficiency Isn’t Enough

Efficiency gains in vehicles and logistics help, but they’re not enough. The 25% increase in freight demand between 2000 and 2019 erased many of those benefits.

Trucks carried 31% more goods in 2019 than in 2000. Meanwhile, rail and waterways grew only 5%, shifting more freight to roads.

Even with 15% lower energy use per tonne-km, total emissions rose. Longer distances, higher loads, and more road-based freight explain the trend.

🔍 Breakdown of Emission Drivers (2000–2019)

According to a recent EEA report, key factors include:

• Freight demand (main driver)

• Increased truck modal share

• Vehicle efficiency improvements

• Carbon intensity of fuels

• Biofuel adoption (with mixed results)

These findings show that demand control and a modal shift are critical—alongside tech upgrades.

🚆 Shift to Efficient Modes of Transport

Shifting from trucks to rail or inland waterway can cut freight emissions. For passengers, moving from cars to buses, coaches, or rail reduces per-kilometer emissions.

Public transport is more GHG-efficient than cars or planes.
Urban buses, if powered by electricity or hydrogen, can further cut emissions while increasing HDV use.

🏭 The Transport Sector’s Role in the EU Green Deal

Transport makes up nearly 25% of EU GHG emissions. To reach climate neutrality by 2050, the EU must cut transport emissions by 90%.

This means deep changes:

• Smarter freight management

• Incentivizing modal shifts

• Investing in cleaner technologies

• Building zero-emission infrastructure

Every part of the sector must contribute.

⚙️ Improving Truck Efficiency

Trucks drive long distances and burn large amounts of fuel. Improving aerodynamics, powertrains, and fuel efficiency can cut emissions significantly.

Businesses are already motivated—fuel is a big cost. Logistics improvements like better route planning and heavier load optimization also help reduce fuel use.

🌱 Biofuels and Their Limitations

Biofuels are considered carbon-neutral, but their real impact depends on the feedstock. Crops grown for biofuel can cause indirect land use change, which offsets the benefits.

So while biofuels play a role, they’re not a silver bullet.

🔋 EU Vehicle Emission Regulations

To curb emissions, the EU introduced CO₂ standards for new HDVs. Targets include:

• 15% reduction by 2025

• 30% reduction by 2030 (vs. 2019/2020 baseline)

These targets currently cover large trucks. The EU plans to extend them to:

• Buses and coaches

• Smaller trucks

• Trailers

• 2035 and 2040 targets

Since 2020, the EEA tracks CO₂ data to measure progress.

🚧 National-Level Actions and Support

Member States are taking additional steps:

• Electric road systems

• CO₂-based truck tolling

• Rail freight improvements

• Zero-emission urban buses

Countries must also support battery-electric and hydrogen trucks with charging and refueling infrastructure.

🛣️ Demand Management and Future Strategy

Reducing emissions needs a blend of strategies:

• Avoid: Cut trip lengths and numbers

• Shift: Move to low-emission modes

• Improve: Boost tech and fuel efficiency

This ASI framework (Avoid–Shift–Improve) offers a comprehensive path to decarbonize road transport.

✅ Conclusion: A Multi-Solution Path Forward

Road transport decarbonization needs:

• Clean technology adoption

• Smarter freight and logistics

• Efficient, public transport alternatives

• Strong EU policy backed by national actions

Each solution alone won’t be enough. But together, they can drive meaningful change toward a climate-neutral Europe.
