|Gas trucks are also a dead-end to decarbonise trucking: the Scania and Iveco trucks with spark ignition engines recorded tailpipe greenhouse gas (GHG) emissions just 3 to 5% lower than the diesel truck with the lowest test result. Volvo’s LNG truck with high pressure direct injection (HPDI) reduces emissions by 14%. However, T&E calculations show that when the extraction and transportation of the gas, including methane leakage, is factored in, spark ignition LNG trucks are worse for the climate than diesels, while HPDI gas trucks are only delivering a small benefit.
Despite this, fossil gas used in transport is supported by EU governments with tax breaks, road toll exemptions and subsidies (see table below). Without these subsidies there would be no market for gas in transport.
Cornelis concluded: “The gas industry is desperate to convince policymakers that gas trucks have a climate benefit because they want to grow their market. The simple fact is that it’s a fossil fuel just like oil and coal, so it needs to be phased out.”
