Cardiff-based freight firm FSEW has joined forces with Rockwool UK to help the manufacturer cut carbon emissions from its UK delivery operations by using electric and biomethane-powered HGVs.
The vehicles are being used on selected routes from the manufacturer’s insulation factory in Bridgend, Wales and have delivered a 630-tonne reduction in CO2 emissions in just 15 months, equivalent to the levels that can be removed from the atmosphere by 13,500 mature trees each year.
The partnership has seen 22% of Rockwool UK’s deliveries made using low carbon vehicles, supporting the group’s global goal to reach net zero by 2050 and to cut emissions by one third by 2034.
Rockwool UK began working with Cardiff-based FSEW at the end of 2023, with the launch of a trial of the initiative.
In its first full year in 2024, the partnership reduced Rockwool UK’s logistics footprint by over 433 tonnes of CO2.
By the end of the first quarter in 2025, a further 200 tonnes had been saved, and additional routes have now been transitioned, including those in the Midlands, the North of England and Scotland.
Digital twin route mapping ensures the electric and biomethane vehicles can refuel on their delivery journeys without any disruption or delay for customers.
Tim Eaton, Rockwell UK supply chain director, said the partnership had already reaped measurable results and the organisation was now looking to extend the initiative further.
“Tackling freight emissions is one of the toughest challenges in construction, but our partnership with FSEW shows it can be done and done without compromise on speed, reliability or service to customers.
“We’re really happy with the results so far and look forward to building on them in the future,” he added.
Nick Wilson, Rockwool’s MD for the UK and Ireland, commented: “With transport and distribution emissions rising on customer agendas, this partnership not only reduces the carbon footprint of our own deliveries, but also paves the way for scalable, additional low-carbon freight solutions that support the UK’s net-zero agenda.
“Through collaborations like this as well as deploying in-house technological solutions, we will continue working hard to reduce our carbon footprint in line with Rockwool Group’s global targets.”
