Study suggests more focus on medium, heavy truck emissions

A new study examining long-term trends in the contribution of transportation to total U.S. greenhouse gas emissions suggests that medium-and heavy-duty trucks could be the next frontier.

The study by the University of Michigan found that the relative contribution to total U.S. emissions of the largest sector, industry, decreased from 1990 through 2014. The transportation, commercial, residential and agriculture sectors increased their contribution to emissions. In transportation, most of the increase came from medium and heavy trucks rather than passenger cars and light trucks.

Based on the results, the researchers say we can expect more emphasis on reducing emissions from non-industry sources, including transportation especially medium and heavy trucks.
