The construction sector holds significant potential for reducing its climate impact

The construction sector holds significant potential for reducing its climate impact.

This was clear from the Roundtable presentation about the Danish project “4 to 1 Planet”, a project funded by the Real Dania foundation and the Villum foundation. The scope of the project is to find ways to reduce the CO2 emissions in new buildings by more than 40% to 2,5 kg/m2.  

The project builds on scientific evidence and gathers ideas and best practices to showcase innovative techniques and materials to achieve a more sustainable construction sector. Among the innovations presented were a new type of insulation slates made from seaweed, a new type of tyles made with a biobased material and that could be produced with minimal heating compared to current production methods, and a “sandwich” structure made from straw for insulation. 

These trends are important for FRACTION as the project will develop new types of insulation foams, coatings, adhesives and polyurethane – all made from lignocellulosic biomasses. 

To push the construction sector towards more sustainable practices it is fundamental to gain critical mass. Talking to stakeholders play a big role, and it is important to identify a wide group of stakeholders that together can make a push forward. For example, companies producing construction materials, architects, building companies, insurance companies, real estate brokers, government, institutions, banks and other are all important for pushing sustainable construction forwards.
