By transitioning from diesel to Hydrotreated Vegetable Oil (HVO), Dublin Airport has achieved a 90% reduction in carbon emissions from its airside vehicles.

After a successful trial conducted between April and May, which involved 12 vehicles, Dublin Airport has now implemented the switch from diesel to HVO.

Dublin Airport is aiming for around two thirds of its vehicles to be powered by HVO by the end of this year.

Andrea Carroll, Head of Environment Sustainability at daa, the operator of Dublin Airport, said: "Switching to HVO is another positive step on Dublin Airport's journey to becoming a net zero carbon business by 2050. HVO is a low carbon alternative to electrification, which is particularly helpful when it comes to larger vehicles that may not currently have an electric alternative, such as tractors. By changing diesel vehicles to HVO, Dublin Airport will save 400 tonnes of carbon emissions annually – the equivalent to the annual carbon emissions of 72 average Irish homes.

"In addition to carbon savings, the switch to HVO provides many other benefits, given it doesn’t require any additional infrastructural investment as all existing diesel tanks and engines can be used. HVO is also proven to work better in colder temperatures (down to -30 degrees Celsius), making it more reliable in the winter months."
