IEA: improving efficiency of road-freight transport critical to reduce oil-demand growth; three areas of focus

Green Car Congress

Road freight transport relies primarily on diesel, which accounts for more than 80% of its oil use. Road freight vehicles alone accounted for about 80% of the global net increase in diesel demand since 2000, and make up about half of global diesel demand today. The trucking sector can improve logistics and systems operations.
