">Black smoke was once the inky signature of diesel engines everywhere. Now it has all but disappeared. A 1998 model year truck actually belched 35 times more smog-producing NOx and 60 times more particulate matter than equipment built to meet 2010 emissions standards, and that's before regulators turned their attention to greenhouse gases.
The trucking industry's environmental gains have not been limited to diesel, of course. Clean-burning fuels from natural gas to propane autogas, and even battery power, are now viable options, especially where medium-duty trucks and predictable operating ranges are involved. Nikola Motors has taken a further leap, pledging to produce electric Class 8 trucks as early as 2020, and Tesla says it will unveil one come September.
Still, there is no mistaking a change in the underlying business climate. Steep diesel prices helped to make the business case for alternative-fueled equipment, which tends to come with premium price tags. Now diesel is relatively cheap. A new administration in the White House, meanwhile, wants to slash funding for the U.S. Environmental Protection Agency, which largely sets the emissions rules.
But don't prepare to burn coal dust just yet. The push for cleaner air continues, even if it originates from a source other than the federal government. California, for example, remains committed to reducing greenhouse gases to 1990 levels by 2020. “In California we are not debating climate science,” said Jack Kitowski, chief of the California Air Resources Board's mobile source division, in a presentation during the Green Truck Summit in Indianapolis earlier this year. “The facts will end up speaking for themselves.”
Then there's the fact that increasingly, truck makers are designing for a global audience, and while President Trump may have just pulled out of the Paris
