Natural gas vehicle production and sales declined in 2015 compared to 2014, mostly as a result of the reduced cost of petroleum, Matthew Godlewski, president of NGVAmerica, told an audience at the Work Truck Show. While overall use and sales of natural gas vehicles were down, particularly for the light-duty segment, which saw a significant drop, and the medium-duty segment, which declined, but at a lesser rate, according to Godlewski.
