Why So Many Non-BEV Trucks in NACFE's Run on Less? - CleanTechnica

The North American Council for Freight Efficiency’s (NACFE) "Run on Less" initiative showcases a diverse range of freight trucks, including battery electric vehicles (BEVs), renewable diesel tractors, natural gas trucks, and hydrogen fuel cell units. This variety reflects the real-world choices fleets are making, but it also raises questions about why many trucks do not outperform others in terms of cost efficiency or greenhouse gas emissions when normalized for comparable metrics. NACFE aims to clarify this by emphasizing two key metrics upfront: cost per mile (the energy cost to move a loaded truck over a specific route) and well-to-wheel emissions per mile (greenhouse gases from energy production through use, normalized to 1,000 miles). These metrics are contextualized by factors such as duty cycle, location, and energy source characteristics, including grid carbon intensity and fuel production methods. The article details how these metrics are calculated for different truck types, incorporating realistic efficiencies, energy losses, and emissions from fuel production and use. For
