We are working with our sister businesses in the Morrisroe Group to reach net zero targets, aiming to be carbon net zero in relation to scope 1 and 2 emissions by 2030. This will involve moving all of our transportation and haulage fleets over to alternative (non-diesel) fuel sources, as well as moving our energy tariffs over to 100% renewable sources.

Progress in FY25

Emissions from our HGV and Tipper fleets are the largest component of our Scope 1 and 2 emissions. Our target of moving all NRMM plant to HVO to reduce emissions and improve energy efficiency continues to make progress, and we have made significant reductions in emissions from our NRMM fleet. In FY25 as a Group, we doubled the use of HVO Biodiesel, using 150,000 litres of HVO as opposed to white diesel. HVO fuel now makes up around 50% of our NRMM fuel.

We can also utilise river-based transportation using barges and pontoons when available, which can result in significant reductions to CO2e of the materials being transported.

Moving forward, we are committed to reducing emissions by migrating to low emissions fuel for our HGV fleet. This will be achieved by upgrading our fuel storage capability and refuelling at our yard premises.

Scope 3 emissions targets

In relation to our indirect scope 3 emissions, we’re committed to using 100% net zero concrete by 2050 and meeting ambitious interim targets involving procuring 30% low emissions concrete on all projects by 2025 and 50% by 2030.

Concrete Zero commitments

We have made these commitments as a signatory to ConcreteZero, an industry initiative driven by the Climate Group together with World GBC and the World Business Council for Sustainable Development (WBCSD).

Morrisroe is a founding member of ConcreteZero. Members include several of our clients as well as leading engineering and design practices such as Mace, Multiplex, Lendlease and WSP UK.

Accelerating Concrete Decarbonisation Group

We are also involved in an initiative that aims to tackle the systemic barriers to the optimisation of concrete design and construction. This group pools the expertise of leading engineering practices and concrete specialists, as part of Derwent’s Accelerating Concrete Decarbonisation Group. Together, we are developing and testing low carbon concrete prototypes for different building typologies. This is a timely piece of work in view of the decreasing availability of GGBS, a costly product which many of our clients have to specify due to there being few alternatives for reducing the CO2e of concrete.
