Clean Transportation
ERG supports clean transportation at all levels of government in the U.S. and abroad. We help agencies ensure that engines and vehicles in use now are as clean as possible, while also supporting the transition to use of 21st century, low-carbon transportation technologies. At ports, airports, rail yards, construction sites, and on roads, our multidisciplinary transportation experts monitor and reduce emissions; plan and implement fleet electrification; calculate and model life cycles and cost-benefits of alternative fuels and technologies; and galvanize stakeholders to improve air quality and reduce climate impacts from transportation.
