Environmental sustainability

Our goal is to be a pioneer in low-carbon and sustainable infrastructure construction. We actively reduce our carbon dioxide emissions, utilize circular economy solutions, and promote biodiversity through our projects. We take the entire supply chain into account in our work, enabling our actions to support our customers in achieving their own low-carbon targets.

Our environmental sustainability efforts are based on managing and reducing the environmental impacts of infrastructure construction and maintenance. Our operations are guided by a certified ISO 14001 environmental management system, which covers all areas of our business and ensures systematic environmental management at every level.

Low-carbon operations

We monitor our greenhouse gas emissions comprehensively and have set ambitious reduction targets. For our own direct emissions (Scope 1 & 2), our goal is to achieve a 100% reduction by 2030 compared to the 2020 level. We will reach this target by gradually transitioning to renewable electricity, increasing the use of renewable fuels, and improving the energy efficiency of our worksite equipment.

Clear targets have also been set for indirect emissions across our value chain (Scope 3). We aim to reduce emissions from material procurement, such as concrete, steel, and asphalt, by 30% by 2030 compared to the 2021 level. Achieving this requires close collaboration with stakeholders, active use of low-carbon materials, increased utilization of renewable fuels, and continuous promotion of circular economy solutions.

Circular economy

Resource efficiency and respect for nature guide our daily operations. In our projects, we use materials efficiently and favor recycled solutions. We integrate circular economy principles already at the design stage and work to prevent waste generation. Our projects are carried out sustainably, with respect for local natural values and in compliance with regulatory guidelines.

We also develop new methods that support the principles of the circular economy. For example, together with our partner, we have developed a gravel road maintenance method that uses a stabilisation solution developed from fibre waste produced as a by-product of the pulp industry for remediating frost-heave damage. Based on testing in 2025, this method can reduce the carbon dioxide emissions of road maintenance by more than 60% while lowering costs by around 10% compared to traditional methods.

Biodiversity

Preserving biodiversity is an essential part of sustainable infrastructure construction.
We mitigate biodiversity loss and promote biodiversity through our projects. In doing so, we strengthen the vitality of ecosystems and support sustainable construction. Even small actions make a difference. For example, we have installed birdhouses in suitable locations, including our aggregate areas.

Together with the Finnish Environment Institute, we are also developing solutions to promote biodiversity as part of our aggregate operations. At our sites in Hervanta and Sorila, we are testing the impact of the submerged timber method on the runoff water of the quarry areas. The method is based on the Finnish Environment Institute’s PuuMaVesi project, in which embedded timber is used to promote biodiversity in water bodies.
