Six new electric vehicles have been delivered to two airports in the Vale of Glamorgan.
The new fleet of Maxus T90s, designed to cut carbon emissions, is being shared between Cardiff Airport and the St Athan Aerodrome.
They are the first electric pick-up vehicles available in the UK and will be used at both sites by security and car park staff, as well as airfield operations and bird control teams.
The Rhoose airport says its CO2 emissions have dropped from 1700 tonnes to less than 600 tonnes a year since 2020 - and is now aiming to cut that total by half over the next five years.
Mark Bailey, director of environmental sustainability at Cardiff Airport, said: "These new vehicles are an asset to our teams. Replacing the diesel fleet with electric is helping us improve air quality and cut our CO2 emissions."
"This builds on the fantastic work we’re doing as a business as we continue our journey to achieve carbon net zero."
The airport is now powered entirely by renewable and clean energy sources, having cut its consumption of natural gas by 30%, restricted ground running of engines during anti-social hours and encouraged twin engine aircraft to taxi with one engine.
Other efforts to cut CO2 emissions include replacing assets with more modern and energy efficient technology, a LED lighting replacement programme and continuous descent operations for aircraft on approach, promotion noise abatement.
