April 22 is the official date of Earth Day each year. However, these days, “EVERY DAY is EARTH DAY” in the freight industry. As we celebrate the 49th “official” Earth Day, let’s take a moment to reflect on some of the accomplishments our industry has made with our green impact efforts during the past several decades.
The amount of air pollution produced from big trucks and diesel-fueled engines has always been a concern. Today, our heavy-duty trucks are 99 percent cleaner than the trucks built in 1970 when it comes to causing air pollution. Common pollutants like carbon monoxide, hydrocarbons, nitrogen oxides and particulate emissions have been greatly reduced.
Back in 1970, the average mile per gallon for heavy-duty trucks was a mere 5.5 mpg. That average rose to 6.4 mpg by 2010. But a recent study sponsored by the NACFE used seven different commercial rigs with varying specs that were driven by experienced drivers. Researchers found that the lowest average for all was 8.8 mpg. Overall, the trucks averaged 10.1 mpg, with one having a 12.8 mpg and three others having days where they reached an average fuel efficiency over 12.5 mpg. The lowest mpg recorded during the approximate 3-month study was one truck that clocked 7.1 mpg one day during the study.
The complete answer to eliminating truck emissions is the completely electric semi. Tesla and Thor are building these trucks. Meanwhile, Volvo has developed electric truck battery technology that it plans to share across its brands, including Mack Trucks in the United States.
Overall, the green impact made by the freight industry is impressive. But it is no time to rest on our laurels and think our job is done. There is still more work to be done, especially with the EPA and the state of California giving the trucking industry until 2021 to make improvements and comply with their new set of standards.
