Can you briefly describe Wallenstam’s sustainability work?

“We want to contribute to a better society, both today and for future generations. Sustainability is central to our operations, and we believe integrated sustainability work and strong community engagement go hand in hand with long-term profitability.

To clarify our ambitions, we have linked our climate targets, approved by the Science Based Targets initiative, to our business plan running to 2030.

The targets mean reducing scope 1 and 2 emissions by 50% by 2030, using 2018 as the base year. We have also set a voluntary scope 3 target to reduce new-construction emissions by 55%, using 2019 as the base year.”

Plant’s tool enabled Wallenstam to calculate the outcomes of proposed project changes and guide us on which materials or changes to prioritise.

Wallenstam significantly reduced CO2 emissions across all scopes last year. Which initiatives led to this?

“Before setting targets, we needed to measure and calculate our actual emissions. This is a vital first step: only when you know your starting point can you set targets and begin reducing emissions.

Our climate targets have been adopted by both group management and the board and form part of our business plan. This makes the company’s position and shared direction clear to everyone. Internal collaboration has been crucial. We identified key measures and implemented them in daily work, creating a clear structure for progressively reducing emissions.”

How has working with Plant influenced Wallenstam’s sustainability work?

“Wallenstam signed a framework agreement with Plant in 2021. In 2023, we developed a scope 3 climate roadmap together. It sets annual milestones towards our final target of reducing emissions by 55%.

We use Plant’s tool for climate calculations in all new-build projects. Based on these calculations, project managers can adjust material choices and quantities to meet our target. One measure we have chosen is lower-carbon concrete. Thanks to the calculations, we can report new-construction emissions annually.

Plant has been a very good partner, responding to our wishes for both the process and report layout.”

What have been the greatest challenges, and how have you overcome them?

“Reducing emissions is a major challenge for Wallenstam. One of the greatest difficulties is ensuring we invest in measures that deliver the most for the money spent. Plant’s tool has helped us analyse scenarios and identify the most effective materials and measures.”

Which climate calculations have been most valuable?

“To better understand our emissions, we ran a pilot calculation of a reuse project. Plant’s new Remodel tenant adaptation tool was particularly useful. It let us compare emissions with and without reuse, giving us better insights for future projects.”

How will Wallenstam continue reducing carbon emissions and reach its 2030 targets?

“Our climate roadmap continues to guide project managers towards environmentally friendly choices. Staying alert to market developments and new innovations is also important. We recently joined a reuse hub that we believe and hope will help the whole industry move towards a more circular economy.”
