Zero-emission electric commercial vehicles appear likely to become routine in the years ahead, but now 49% of all Classes 3-8 commercial vehicles, or nearly 5.5 million trucks, already are using advanced diesel engine technology to reduce greenhouse gas emissions, according to a new study.
“This advanced generation of diesel is a bridge technology that is delivering carbon dioxide reductions that are very important now,” Diesel Technology Forum Executive Director Allen Schaeffer said during a recent online presentation.
A few days later, scientists reported the all-time high CO2 level in May, as recorded in Hawaii — an average of 419 parts per million compared with the previous record of 417 parts per million a year earlier.
AutoForecast Solutions, in research the Diesel Technology Forum commissioned, found that since 2007 the newest-generation diesel trucks on U.S. roads eliminated 202 million tonnes of CO2, 27 million tonnes of nitrogen oxides and 1.6 million tonnes of particulate matter. They also saved almost 20 billion gallons of diesel and 296 million barrels of crude oil.
The study predicted the growing number of more efficient diesel trucks on the road will eliminate 1.3 billion tonnes of carbon dioxide between 2020 and 2030.
