In a sector as demanding and sensitive as the transport of chemical liquids and dangerous goods, regulatory evolution is a constant that forces companies to adapt to ensure safety, efficiency and legal compliance. In 2025, the entry into force of the Euro 7 regulation for heavy goods vehicles represents a disruptive change in sustainable mobility, with a particular impact on tanker fleets operating in France, Spain and the rest of Europe.
What is the Euro 7 standard?
Euro 7 is the new European standard regulating pollutant emissions from vehicles, stricter than its predecessors (Euro 6 and earlier). It aims to drastically reduce gases such as NOx, particulate matter and volatile organic compounds, with the objective of improving air quality and meeting climate commitments.
For heavy-duty vehicles, Euro 7 includes:
-
Tighter emission limits even in real driving conditions (RDE, Real Driving Emissions).
-
Regulation of ammonia and nitrogen oxides (NOx) emissions during the entire vehicle life cycle.
-
New measurement methods and on-board diagnostic (OBD) systems.
Direct impact on the transport of chemical liquids with road tankers. Tanker trucks transporting chemical liquids face a double challenge: on the one hand, the need to maintain safety and leak-tightness; on the other hand, the need to comply with new environmental requirements.
Key adaptations for fleets:
- Renewal or retrofitting of engines and aftertreatment systems to comply with Euro 7 limits, which may involve significant investment in new vehicles or fleet upgrades.
- Implementation of advanced telematics systems to monitor environmental performance and emission status in real time.
- Specific training for drivers and fleet managers to ensure efficient and environmentally friendly driving.
- Updating of preventive maintenance protocols with emphasis on emission-related components.
International compliance: France and Spain as key markets
Both France and Spain are pioneers in the implementation of Euro 7, with strict implementation schedules and strong controls.
- France has established incentives for fleets to adopt Euro 7 vehicles and severe penalties for non-compliance, especially in urban and peri-urban low emission zones.
- Spain, through the DGT and relevant ministries, is promoting adaptation with aid for fleet renewal and roadside technical audits.
The Euro 7 regulation is an unstoppable reality that marks a before and after in road transport, especially in the chemical liquids sector. Adaptation is not only a legal obligation, but an opportunity to consolidate the position in an increasingly demanding and sustainable market.
