In the fourth annual State of Sustainable Fleets Market Brief, a new trend is clear — public policy and funding has shifted sharply to build the ZEV market and sunset diesel engine development on an accelerated timeframe. Report author and leading clean technology consulting firm, Gladstein, Neandross & Associates (GNA), unveiled the findings at the Advanced Clean Transportation (ACT) Expo, a four-day conference which drew more than 10,000 attendees to Anaheim, California. 

This year’s Market Brief illustrates much more about the future, one where new diesel engine development programs are moving towards a sunset, and zero-emission vehicles (ZEVs) will be the “law of the land” in states representing approximately half of the U.S. economy. The past 18 months have laid the roadmap for a zero-emission (ZE) future in many states and produced early signals that the era of the diesel engine, the workhorse of heavy-duty vehicles, will end sooner than many predicted. Previously, the State of Sustainable Fleets demonstrated that some clean fuels and vehicles are now superior to gasoline- and diesel-fueled vehicles for many fleet applications, and adoption of renewable fuels and advanced technology drivetrains is accelerating. 

“The past year has brought a historic amount of investment from the federal government, as well as from private industry,” said Erik Neandross, CEO of GNA. “Across clean fuel types, we’re seeing accelerating momentum and an increasing commitment to low carbon fuels and zero emission commercial vehicles.”  

This year’s report offers another deep analysis into the alternative fuels and clean transportation markets, with the following findings:
