Do gas trucks reduce emissions?

A number of truck manufacturers claim that trucks running on gas deliver strong air quality and greenhouse gas benefits compared to diesel. On-road tests commissioned by the Dutch government were performed by TNO, an independent research organisation, to compare emissions from diesel and liquefied natural gas (LNG) trucks. This paper outlines how the on-road data shows that many of the truckmakers’ claims are false. It also outlines how most EU governments are encouraging the uptake of polluting LNG trucks with extremely low tax rates on fossil gas for transport.
