The International Road Transport Union (IRU) and Transport and Environment (T&E) are demanding European Commission President Ursula von der Leyen convene urgent talks on decarbonizing heavy-duty vehicles as EU emissions rules face regulatory review and mounting energy and cost pressures threaten to derail the sector's transition away from fossil fuels.
Road transport accounts for roughly 27 percent of EU transportation emissions, with heavy-duty trucks and buses representing the largest share of that burden. The sector has lagged passenger vehicle electrification efforts, partly due to infrastructure gaps, battery technology constraints, and the economic challenges facing haulage operators already contending with fuel price volatility and labor shortages. Europe's truck fleet remains overwhelmingly diesel-powered.
EU regulations requiring heavy-duty vehicle manufacturers to cut CO2 emissions by 55 percent by 2030 and achieve carbon neutrality by 2040 set binding targets. These rules now face scheduled review in 2026, a moment when the regulatory framework itself becomes negotiable. IRU and T&E warn that without renewed political commitment and strategic coordination between stakeholders, the review could weaken ambitions or create loopholes manufacturers exploit.
The organizations cite dual pressures reshaping the landscape. Energy costs have spiked across Europe since Russia's invasion of Ukraine, raising electricity prices and making alternative fuel infrastructure deployment more expensive. Simultaneously, freight operators face tightening margins and reluctance from customers to absorb transition costs. This creates a paradox: the transition requires substantial upfront capital investment precisely when industry faces financial strain.
Battery supply chains remain constrained. Lithium and cobalt sourcing faces geopolitical complications, while manufacturing capacity for heavy-duty batteries lags demand forecasts. Hydrogen fuel cell technology for long-haul trucking remains nascent, with only scattered refueling networks operating across the continent. These technological gaps mean many operators cannot yet access viable alternatives to diesel, even if regulatory pressure increases.
IRU and T&E argue that a strategic dialogue must address several interconnected challenges: harmonizing fuel taxation across member states to level playing fields; accelerating public and private investment in charging and hydrogen refueling infrastructure; ensuring supply chain resilience for batteries and fuel cell components; and creating transitional support mechanisms for smaller haulage companies that cannot absorb transition costs independently. They also want clarity on whether sustainable fuels like e-fuels and biofuels will receive regulatory credit toward emissions targets, a question that shapes investment decisions.
The European Commission under von der Leyen has positioned climate neutrality by 2050 as a cornerstone policy. Achieving that target requires deep decarbonization of heavy transport. Without action now on regulatory certainty and support mechanisms, the sector will not achieve necessary emissions reductions by 2030. Member states including Germany and France, major logistics hubs, have signaled concern about competitiveness if transition policies diverge.
The timing remains critical. Commission reviews of emissions standards typically extend over 18 months. A dialogue launched now could shape revised regulations that balance environmental ambition with economic feasibility, preventing either weakened targets or rules that push operators toward non-compliance. Without high-level coordination, fragmented member state policies risk creating a patchwork that undermines both emissions reductions and market efficiency.
