The transition will include the deployment of smart tanks which will be monitored in real-time to record fuel use accurately.

Sisk will look to mandate the use of Green D+ HVO across all its businesses throughout 2021 and 2022 and aims to expand its use through its supply chain.

Chief operating officer for the UK and Civils Paul Brown said: “This is a major strategic step-change, to stop using a fossil fuel that has been at the core of our business, and it will positively impact our carbon performance immediately.

“This agreement will help us hit our carbon reduction targets in our Roadmap with a potential saving of 22% once all the company is using this fuel and another 21% when we get our subcontractors on board.

“Our Sustainability Roadmap, Building today, Caring for tomorrow, sets ambitious carbon reduction targets for us in our journey to carbon neutrality by 2030 and this is another important milestone on the journey.”

Last year, Sisk claims it was the first construction business in the UK to utilise sustainable HVO fuel, trialling its use on the Sisk UK Civils Northstowe project for Homes England.

Sisk used circa 800,000 litres of Green D+ HVO on its operated plant in Northstowe, and in the year since the trial began, Sisk has been monitoring its effectiveness and planning how to roll it out across the business efficiently and successfully.

The contractor has now entered a framework agreement with Green Biofuels in the UK to supply Green D+ HVO.
