The Challenge of Diesel Emissions in Long-Haul Trucking
The long-haul trucking sector has been under increasing pressure to improve its diesel fuel efficiency as industry leaders grapple with the environmental implications of carbon dioxide (CO2) emissions. Heavy trucks contribute over 3% of total CO2 emissions, prompting efforts toward decarbonization. While modern diesel engines are significantly cleaner due to EPA regulations, many older models remain operational, underscoring the necessity for strategies that mitigate their harmful exhaust.
Michael Roeth, executive director of the North American Council for Freight Efficiency (NACFE), emphasizes in a recent editorial for Fleet Owner that “the trucking sector has made substantial strides in emission reductions while efficiently delivering goods.” He asserts that this success should be more widely recognized and celebrated within the industry.
Assessing Emission Reductions: A Valid Argument?
While Mr. Roeth appears genuinely committed to promoting improvements within the trucking industry, one might question whether reduced emissions from these vehicles are genuinely indicative of meaningful progress towards decarbonization. A thorough analysis is warranted.
Understanding Decarbonization
According to Roeth: “Increasing fuel efficiency translates directly into lower carbon emissions; it’s a form of decarbonization.” He points out that maximizing freight transport per gallon of diesel significantly reduces overall fuel consumption throughout a given day.
The NACFE identifies its mission as fostering advancements in eco-friendly technologies and operational practices within North America’s freight movement ecosystem. As articulated by Renée Cho from Columbia Climate School, achieving decarbonization involves curbing greenhouse gas emissions generated through fossil fuel combustion by transitioning to renewable energy sources like wind and solar power—currently representing about one-third of global power generation capacity—and electrifying various sectors where feasible.
Nancy Stauffer from MIT highlights a pivotal challenge: long-haul trucks predominantly operate on diesel fuel which produces considerable CO2 and other greenhouse gases upon combustion. With global freight transportation demand expected to potentially double by 2050, identifying alternative energy solutions is critical for addressing long-distance trucking while simultaneously decreasing associated carbon footprints.
A Shift Towards Comprehensive Decarbonization Goals
A 2024 report from Climate Impact Partners reinforces this perspective by defining decarbonization as an initiative aimed at reducing anthropogenic CO2 output with aspirations towards complete elimination.
Diverse Approaches Toward Achieving Trucking Industry Emissions Goals
Roeth’s insights reveal an upward trend in fuel economy; he notes that participating fleets recorded an average fuel economy rate of 7.77 miles per gallon (MPG) in 2023 compared to just 6.67 MPG a decade prior. In broader terms across all fleets examined by federal authorities, overall MPG improved from approximately 5.85 MPG in 2013 to about 6.91 MPG as recently reported for the year prior.
This trajectory represents incremental progress rather than definitive roadmaps toward widespread decarbonization within trucking.
Samantha Gross, director at Brookings Institution’s energy security initiative stated earlier this year: “Effective policy often hinges on clear technological pathways—we’re still exploring various options.” This underscores existing divisions regarding optimal methods for achieving significant reductions among stakeholders throughout the industry sphere.
