Denmark leads the way with embodied carbon limits for buildings. From January 1st, 2023, Denmark became the first Nordic country to introduce embodied carbon limits into building regulations.
All new buildings applying for a building permit (from January 2023), have to document the climate impacts through Life Cycle Assessments (LCA).
New buildings above 1000m must comply with the limit value of 12kg CO2 equivalent/m2/year.
New construction under 1000m2 requires LCA calculation without the threshold limit values.
The voluntary threshold limit is set at 8kg CO2 equivalent/m2/year.
Generic data or (Environmental Product Declarations) EPDs can be used for LCA calculations.
