OEMs seek clear and consistent emissions regulations in Canada and U.S.

As the clock ticks down to January 2027, the landscape of emissions regulations looms large for truck and engine manufacturers. After investing years of preparation and billions of dollars, the uncertainty surrounding these regulations is causing significant anxiety and speculation within the industry. The stakes are high, and clarity is urgently needed.

The Environmental Protection Agency's (EPA) proposed NOx regulations aim for an ambitious 82.5% reduction, bringing the permitted levels from 0.2 grams per horsepower hour down to 0.035 grams. However, a recent announcement from the EPA regarding a reevaluation of this rule has thrown manufacturers into a state of confusion, as they wonder if these regulations will be altered, delayed, or scrapped entirely.

Will warranty provisions be modified?

The potential changes to the warranty provisions have become a focal point of discussion among Original Equipment Manufacturers (OEMs). According to Sean Waters, Vice President of Compliance and Regulatory Affairs at Daimler Truck North America (DTNA), there is a possibility that the warranty requirements for aftertreatment equipment could see adjustments due to the time constraints. “This might be an opportunity for the EPA to revert to previous warranty provisions and relieve some of the costs associated with the 2027 product,” Waters suggested.

Krista Toenjes, General Manager of Cummins' North America on-highway business, echoed these sentiments, emphasizing the need for a definitive decision regarding the 2027 emissions standards. “We are currently in a waiting game,” she stated. “Having clear guidelines is essential for our strategy moving forward.” Cummins recently announced a delay in the rollout of its EPA27-compliant engine, highlighting the ongoing uncertainty in the industry.

Fleet operators also feel the pressure. Paul Rosa, Senior Vice President of Procurement and Fleet Planning at Penske Truck Leasing, noted that without clear emissions standards, it’s challenging for fleets to prepare for the future. The looming Greenhouse Gas (GHG) Phase 3 rules, which mandate a specific percentage of zero-emission vehicles from OEMs, further complicate matters, as revisions are anticipated.

Importance of U.S.-Canada regulatory alignment

The need for alignment between U.S. and Canadian emissions standards has never been more critical. The cross-border movement of trucks poses significant challenges for manufacturers, especially when regulations differ between the two nations. Rick Mihelic, Director of Emerging Technologies with the North American Council for Freight Efficiency (NACFE), highlighted that over 4 million vehicles crossed the border in both directions last year, raising concerns about compliance and market share for North American truck makers.

Mihelic warned that a lack of consensus on emissions standards could lead to a situation similar to the border regulations with Mexico, complicating the logistics of compliance and potentially harming domestic manufacturers. “We need to address these discrepancies promptly,” he urged, emphasizing that without alignment, U.S. manufacturers could lose ground to their European counterparts.

Waters added that Canada’s smaller market compared to the U.S. makes regulatory uniformity essential. He pointed out that Canada relies on U.S. certifications for emissions standards, which complicates the introduction of local regulations. Moreover, the different product mix in Canada impacts the types of vehicles offered, further emphasizing the necessity for coherent regulations across the border.

What are the emissions standards in Canada?

Canada's emissions standards have traditionally aligned closely with U.S. regulations; however, recent discussions have introduced the possibility of divergence, particularly with the GHG Phase 3 rules. Currently, Canada has not adopted these regulations, creating uncertainty among manufacturers. The industry is keenly interested in how Canada will proceed, especially given the technological advancements and market readiness.

The Canadian regulatory framework includes:

• Compliance with federal and provincial emissions standards
• Mandatory reductions in greenhouse gas emissions
• Incentives for zero-emission vehicles

These measures are designed to promote sustainability and innovation within the Canadian trucking industry, but they must be balanced with market realities and technological capabilities.

How does Euro 6 compare to U.S. standards?

The Euro 6 emissions standards, implemented in Europe, are among the most stringent in the world and provide an interesting contrast to U.S. regulations. Euro 6 requires a limit of 0.4 grams of NOx per kilometer for diesel vehicles, which is stricter than the current U.S. regulations but also includes different testing methodologies.

Some key differences include:

• Testing conditions: Euro standards often use real-driving emissions testing, while U.S. standards have been based more on laboratory conditions.
• Focus on particulate matter: Euro 6 places a strong emphasis on reducing particulate matter, whereas U.S. standards have historically focused more heavily on nitrogen oxides (NOx).
• Implementation timelines: The European Union has been more aggressive in rolling out new standards, requiring manufacturers to adapt quickly.

This comparison highlights the challenges faced by manufacturers looking to comply with both sets of regulations and underscores the importance of harmonizing standards across different regions to facilitate trade and compliance.

As the industry progresses towards 2027, the development of zero-emission trucks remains a priority. Rosa from Penske emphasized that the investment in electric vehicles will continue, driven by the lessons learned over the past four years. “We are not stepping back from our commitment to EVs,” he stated, reflecting a sense of optimism within the industry.
