Heavy commercial vehicle market increasingly impacted by emissions regulations and geopolitical conflict

Global heavy commercial vehicle sales are expected to be muted in 2026 as the Strait of Hormuz conflict tightens oil supplies and key products coming out of the region.

In 2027, however, sales are expected to rebound, driven by economic growth and a new wave of emissions regulations.

While freight demand, credit conditions, and fuel prices still decide how much the market can grow, emissions regulations are increasingly seen as a catalyst for commercial vehicle market stakeholders: influencing when fleets replace trucks, what they buy, and how OEMs set production plans.

Why emissions regulations are becoming a driver of commercial vehicle demand

Freight demand, macro-economic growth and fuel prices will all remain important factors for the market. But fleet operators and truck manufacturers are also preparing for a new generation of emissions rules that will influence their purchasing decisions through the rest of the decade.

Regulations across three regions stand out: China's proposed China 7 emissions standards, the US EPA 2027 NOx requirements, and Europe's CO₂ standards and Euro 7 rules for heavy-duty vehicles (descriptions of each are available at the end of this article).

Together, these regulations are accelerating fleet replacement cycles, influencing engine development programs, and increasing investment in battery electric trucks.

Here are some key regional highlights from our latest forecast round.

China: Sales strength remains as China 7 regulations and electrification shape the next cycle

Market overview

China’s heavy- and medium-duty truck (HMDT) market has held up better than expected in the first half of 2026 despite clear macro headwinds. Elevated oil prices and policy incentives appear to be pulling replacement demand forward and accelerating interest in alternative-fuel trucks.

Exports have also been exceptionally strong—up roughly 50% year over year in the first five months of 2026—supporting production and reinforcing China’s expanding global footprint.

What’s changing for fleets: Regulation, fuel costs, and supply risk

Mainland China remains the global leader in battery-electric heavy truck production, supported by strong local OEM competition and government subsidies. The market is now preparing for the next step in emissions regulation: China 7, expected later this decade.

Simultaneously, the government’s “Implementation Plan for Promoting the Large-Scale Application of New Energy Heavy-Duty Trucks” signals a national roadmap to scale new energy vehicle (NEV) deployment. With the Strait of Hormuz blockade lifting global oil prices and directly increasing fleet operating costs, China is using this NEV roadmap as a strategic hedge against oil dependency.

Meanwhile, mainland Chinese OEMs are aggressively building channel inventory overseas, which may provide a buffer against supply-chain disruptions but also signals an intent to capture global market share despite heightened trade risks.

Europe: Replacement-led stability drives current environment with CO2 standards and Euro 7 rules pushing electrification

Market overview

Western and Central Europe saw a modest recovery in early 2026, but full-year demand is expected to land roughly in line with 2025 as the second half weakens. Expansion remains constrained by high interest rates, subdued freight demand, high total cost of ownership, driver shortages, and broader geopolitical uncertainty.

The near-term market is driven less by growth and more by overdue replacement: Fleets are retiring aging units to cut maintenance costs, improve fuel efficiency, and reduce exposure to toll systems that penalize higher-emission vehicles.

What’s Changing for Fleets: Regulation, Fuel Costs, and Supply Risk

Europe’s biggest structural demand driver is CO₂ emissions regulation, which pushes OEMs and fleets toward zero- and low-emission powertrains. While the European Commission has introduced compliance flexibilities for 2030 targets due to charging infrastructure delays, the direction remains toward decarbonization.

The industry is also navigating Euro 7 emission rules, with our base-case assumption being end of May 2028 (new type approval) and end of May 2029 (all new vehicles). These regulatory pressures are compounded by the ongoing war in Ukraine and the conflict in the Middle East, which create an unpredictable environment for energy costs and manufacturing inputs.

Furthermore, European OEMs are facing increased competition from Chinese imports, adding a layer of trade-policy uncertainty to fleet procurement. High inflation and war-related economic strain continue to make fleet modernization a delicate balancing act between efficiency needs and capital risk.

North America: Freight recovery supports demand while EPA 2027 remains a major factor

Market overview

North America’s production outlook is broadly stable for 2026–2028. The total North American MHCV production outlook (truck + bus) was lifted 4% for 2026 and is now forecast to grow 11% year over year.

What’s Changing for Fleets: Regulation, Fuel Costs, and Supply Risk

What is EPA 2027 and what does it require?

EPA 2027 refers to the next phase of US heavy-duty truck emissions regulations focused primarily on reducing nitrogen oxide (NOx) emissions from new trucks. In plain terms, it raises the bar in three ways:

• Tighter emissions performance: Lower allowable NOx emissions under a wider range of real operating conditions.
• Stronger durability expectations*: Engines and aftertreatment systems must stay compliant for longer, which pushes OEMs toward more robust designs and validation work.
• Expanded warranty and compliance obligations*: Manufacturers take on longer emissions-related warranty exposure, which typically shows up in higher vehicle prices and more emphasis on correct maintenance and operating practices.

*Note: As of this writing, the Administration proposes to keep MY2026 warranty and durability requirements in place for MY2027-2029 engines, while delaying the tougher durability requirements until MY2030 and effectively canceling the planned MY2027 warranty expansion.

With that baseline, EPA 2027 becomes the biggest regulatory variable in North America. Unlike CO₂ mandates, this is a pollutant-focused rule (NOx) that directly impacts engine complexity, maintenance, and vehicle pricing. While proposed flexibilities may smooth the transition, the rule remains a major driver of OEM build schedules and fleet replacement timing.

These regulatory pressures are currently colliding with geopolitical instability in the Middle East, which has kept fuel costs elevated and introduced new risks to economic activity and trucking tonnage while having a mixed impact on carrier margins. While zero-emissions vehicle adoption remains muted, the focus has turned back to new internal combustion engine programs.

However, due to the proposed changes to the EPA 2027 mandate, these programs may see delays. Fleets must now navigate the risk of supply-chain swings: If demand ahead of EPA27 surges, manufacturing may not ramp up fast enough. On the other hand, if registrations don't materialize, the industry risks a period of over-building and extreme inventory levels.

Conclusion

Across China, Europe, and North America, the next MHCV cycle won’t be driven by freight and GDP alone. Emissions rules are now a first-order demand driver—changing when fleets replace trucks, what they buy, and how fast OEMs push new powertrains and aftertreatment systems into the market.

Near term, the Strait of Hormuz disruption and higher oil prices are a real drag on 2026 volumes and operating costs. But looking into 2027 and beyond, China 7, EPA 2027, and Europe’s CO₂ targets and Euro 7 rules are setting up a new wave of investment as fleets balance compliance, uptime, and total cost of ownership.

Fleet operators should build a replacement plan that’s scenario-based—what you do if rules tighten on schedule, soften, or slip—and align it to your duty cycles and infrastructure reality. The fleets that win through 2027–2030 will be the ones that lock in build slots early, pilot electrification where it actually works today, and protect residual values by avoiding last-minute buying into regulatory cliffs.
