Sustainability

Sustainability in practice

Sustainability is part of how we think, build and improve every day. From the energy we use and the materials we choose to the partnerships we build, we take responsibility for our impact and keep looking for better ways forward. Through continuous improvement, smarter solutions and greater transparency, we work to reduce our environmental impact and help our customers make more informed choices.

A culture of continuous improvement

There is always a better way to do things. That belief shapes our sustainability work, with employees across the company finding ways to help us use resources more efficiently, reduce waste and improve processes.

Certified quality and environmental management

Our management systems are certified according to ISO 9001 and ISO 14001, providing a structured foundation for quality, environmental responsibility and continuous improvement.

Transparency for better choices

We include CO₂e data on our order confirmations. The figures cover raw material supply, transport of materials to production and manufacturing (A1–A3), giving customers insight into the climate impact of each order.

Goals that guide our work

Our GHG Protocol reporting shows that Scope 1 and 2 emissions were 42% below our 2021 baseline. In 2026, we therefore reached our 2030 target four years early. We continue to monitor emissions annually to help sustain this reduction. Our wider sustainability efforts cover product data, employee training, supplier responsibility and transparent reporting.

CDP

In 2025, we received a B score for climate change from CDP. A B corresponds to CDP's Management level, indicating that our disclosure provides evidence that we understand our climate-related impacts and are taking action to manage them.

Smarter use of energy

Improving how energy is used and sourced is an ongoing part of our work. Depending on the site, our measures include equipment upgrades, heat recovery from production, solar heating and fossil-free electricity.

Responsibility across the chain

Our Codes of Conduct set expectations for employees and suppliers, supporting human rights, fair working conditions, environmental responsibility and ethical business practices.

People and progress

We have participated in Produktionslyftet, strengthening our capacity for improvement, renewal and learning. In 2010 we received the Visa vägen award for our approach to diversity in the workplace.

From materials to end of life

The environmental impact of a product is shaped throughout its life cycle. From material selection and product design to packaging, performance in use and end-of-life considerations, we look for ways to reduce impact without compromising function or reliability.
