\u2018Clean\u2019 gas trucks myth exploded by on-road tests<\/strong><\/h3>\n

Claims by truckmakers and the gas industry that LNG-powered trucks are clean have been severely undermined by recently published results of on-road tests. Trucks powered by liquified natural gas (LNG) can pollute the air up to five times more than diesel trucks, according to the tests commissioned by the Netherlands government. They are also as bad or little better in terms of greenhouse gas emissions, according to additional analysis by T&E based on the test results. T&E said the results show gas trucks offer no clean alternative to diesels.<\/p>\n

The three LNG trucks tested emit 2 to 5 times more poisonous NOx than the diesel truck with the lowest test result when driven in a combination of urban areas, regional routes and motorways. When driven in towns and cities, the gas trucks release 2 to 3.5 times more NOx than the tested diesel truck with the lowest emissions. Trucks run on biogas (biomethane) would have comparable air pollutant emissions as fossil gas trucks because the fuel characteristics are the same.<\/p>\n

Truckmakers have long claimed that gas trucks cut nitrogen oxide (NOx) emissions. In 2016 Iveco said<\/a> its Stralis gas truck reduced NOx emissions by 30% \u2018to a bare minimum\u2019. Scania claimed<\/a> NOx pollution would be cut by \u2018more than a third\u2019 in gas trucks compared to diesel.<\/p>\n

T&E, which published the test results commissioned by the Dutch government, said EU governments should stop encouraging the uptake of polluting LNG trucks by ending the extremely low tax rates that fossil gas for transport enjoys in most countries. As gas is little or no better than diesel for greenhouse gas emissions, EU and national lawmakers should focus on promoting zero-emissions vehicles instead of sinking resources into gas infrastructure and incentives for LNG trucks.<\/p>\n

T&E\u2019s clean trucks manager, Stef Cornelis, said: \u2018Gas trucks are not clean and can actually be worse than diesel. It\u2019s time for policymakers to have a fresh look at the evidence and put an end to gas truck subsidies, LNG infrastructure investments and tax breaks for what is just another polluting fossil fuel.\u2019<\/p>\n

The on-road tests also show that all three gas trucks tested produce levels of particle emissions comparable to diesel trucks. Particles can penetrate deep into the lungs and be absorbed into the blood, causing heart disease, strokes and lung cancer. These findings are in sharp contrast to truckmakers\u2019 advertisements claiming that with LNG trucks particle emissions are almost completely eliminated.<\/p>\n

Gas trucks also do not offer a pathway 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\u2019s 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.<\/p>\n

Despite this, fossil gas used in transport is supported by EU governments with tax breaks, road toll exemptions and subsidies. Without these subsidies there would be no market for gas in transport.<\/p>\n

Stef Cornelis concluded: \u2018The 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\u2019s a fossil fuel just like oil and coal, so it needs to be phased out.\u2019<\/p>\n
