UK infrastructure-services firm FM Conway expands use of renewable diesel

U.K.-based infrastructure-services company FM Conway has extended its use of hydrotreated vegetable oil (HVO) in its local and strategic highways operations, shifting away from diesel in its work to achieve net zero, the company announced in October.

The waste-based biofuel provides up to 90 percent CO2 savings as well as benefiting air quality through reduced nitrogen-oxide and particulate-matter emissions.

FM Conway projects the move will save around 3,000 metric tons of CO2-equivalent through to the end of the current financial year.

In April 2025, FM Conway will assess the feasibility of making a permanent switch to HVO.

This investment marks a major step in the company’s road to net zero, and the carbon savings are the equivalent of taking 60 heavy-goods vehicles off the road for one year.

While exploring longer-term solutions for the replacement of fossil fuels across the industry, HVO provides significant emission reductions and helps FM Conway and its clients reach their shared net-zero ambitions.

The fuel will be supplied by New Era Energy, whose delivery trucks will also be powered by HVO, maximizing carbon savings across the supply chain.

The sustainability of the product’s feedstock is accredited to the International Sustainability and Carbon Certification System GmbH, which supports climate-friendly supply chains.

The traceability of feedstocks is also approved through Zemo Partnership’s Renewable Fuels Assurance Scheme, which verifies companies’ claims on greenhouse-gas emission savings and raw-material sources for renewable fuels used in heavy-duty vehicles.

“We are already tackling embodied carbon through our pioneering material-circularity approach, and this switch to HVO represents another step toward making CO2 savings and improving the air quality across all phases of the works we deliver,” said Matt Tallon, the sustainability director at FM Conway. “It supports our ethos of leading positive change in the infrastructure industry through experimentation and innovation. Our self-delivery model allows us a greater degree of independence and flexibility with our operations, processes, products and fleet, giving us room to test different approaches and ultimately deliver benefits to our clients. The extended run of this trial, until April next year, will give our clients a taste of what’s available and achievable—and how they can use it to accelerate their own decarbonization journey.”

FM Conway recently secured British Standards Institute (BSI) PAS 2080:2030 certification for its management and reduction of whole-life carbon in infrastructure and the built environment.
