Investing in renewables and energy efficiency at our factories

Enabling near-zero emissions in production

As part of the VELUX Group’s ongoing efforts to reduce emissions from our own operations and ultimately to deliver on our target of 100% reduction in our operational emissions, we are continuously improving the energy efficiency of our production process. 

Through a combination of efforts at our most energy-consuming production sites, from optimization of paint line ventilation and wood chip extraction to heat pumps and other renewable solutions, we expect to save about 10,000 tonnes of CO2e annually once all of the currently planned projects become operational.

Extracting energy savings  

The bioboilers in our production plants run solely on biomass, in the form of wood waste, from the FSC or PEFC-certified wood, generated during the production of our windows. Chip extraction systems suck up wood chips created during the production process and collect them for use in the bioboiler. 

Improving the working environment  

Paint line ventilation is highly energy intensive due to the suction processes that serve to remove paint particles from the air during lacquering and drying. The filtering system also involves heat exchange with fresh air outside the building to retain heat while ensuring the indoor air is free from traces of harmful levels of dust and particles. In the new systems, a control mechanism is introduced to ensure that only the necessary suction pipes are powered. This optimisation not only saves energy but also helps to ensure employees are working in a comfortable and well-ventilated space. 

Ending our reliance on fossil fuels  

These improvements build upon our work to eliminate reliance on fossil fuels in our production processes. In 2023 we invested in two new renewable heating projects, by converting a factory in France to a new bioboiler and connecting a factory in Denmark to renewable district heating. 

Investing in renewable energy supports our ambition to minimize the carbon footprint of our own operations (scopes 1 &2). By 2023, we have already more than halved our scope 1&2 emissions, from 52 tonnes CO2e to 23 tonnes CO2e since 2020. This puts us on track to achieving our operational emissions target by 2030.

Ecovadis platinum rating

In 2025, VELUX achieved Platinum status in the annual EcoVadis sustainability assessment – a significant milestone that marks our progress from a Gold rating in 2024. With a score of 86 out of 100, up from 78 last year, we are now placed in the top 1% of more than 150,000 rated companies worldwide.

Our commitment to protecting biodiversity and nature

Nature and biodiversity are the foundation of life as we know it. Our commitment to protecting biodiversity is more important than ever - not only because species have an inherent right to exist, but also because our survival depends on the ecosystems they sustain.

Altaterra introduces waste-handling solution to reduce emissions

Tackling operational waste and reducing transportation emissions are two critical challenges that must be addressed in the global push towards decarbonisation. Altaterra, part of the VELUX Group, is aligning with these objectives by adopting innovative waste management solutions that reduce both physical waste and carbon emissions.

Celebrating four years of the WWF-VELUX partnership

As of September 1, 2024, we mark the 4th anniversary of the WWF-VELUX partnership, an initiative dedicated to protecting and restoring forests and improving livelihoods. Over the past year, our joint efforts have seen substantial progress within the countries in which we work.

BayWa 2024 Update

In 2022, the VELUX Group signed two new virtual power purchase agreements with BayWa r.e. that will drive the development of two new solar (photovoltaic) PV parks in southern Spain. The solar plants will generate 167 GWh of renewable electricity annually. That is enough power to cover all the VELUX Group’s European operations today - and several years ahead - and it constitutes about 90% of our current global electricity consumption. Enabling new solar plants is part of our work to achieve 100% renewable electricity and will help us reach the emissions reduction target for our global operations by 2030.
