Carbon Footprint Tool for the Construction Industry Making accurate emission understanding accessible to all, empowering even non-experts to confidently own carbon reduction decisions from early-stage to project completion. On a mission to accelerate sustainable construction the story Founded in 2021, Reduzer was started with a mission to accelerate sustainable construction and help the industry make better decisions - earlier in the project. We truly believe that good, sustainable choices can be made across all phases of a project, but the earlier the better. Based on research from Norwegian University of Science and Technology (NTNU) and Technical University of Denmark (DTU), Reduzer is now an emerging software for carbon calculations across the construction industry and is trusted by more than 70 customers across the Nordics. The software is used widely in many construction projects, spanning from developer and architects to consultants and contractors. In 2025, Reduzer secured a financing round led by Momentum Partners, Futurum Ventures and Construct Venture - with the aim to continue developing the platform and enable more sustainable construction. We are a team of 15 dedicated people with a passion for sustainability and for making it accessible to everyone through smart software solutions. Our headquarters are located in Oslo.
