While some experiences from the Swedish case could be applied to the EU context, further EU support to Member States could also significantly simplify the harmonisation and implementation of WLC frameworks. Ambitious limit values on WLC, better valuing of existing building stock, expanding buildings’ lifespans and circularity, and fostering demand for low-carbon materials are all important levers to decarbonise the built environment. These measures could be implemented or strengthened in a range of existing policies.
