BR18 climate requirements - EPD

The new stricter climate requirements mean that developers must document the building's total carbon footprint through a life cycle assessment (LCA) before an occupancy licence can be granted. The requirements apply to all new buildings that are already covered by the energy framework - and come into effect when applying for a building permit.

It's an important step towards a greener future where responsibility and documentation go hand in hand.

As of 1 July 2025, the following climate requirements apply:

• All new buildings must have a climate calculation (LCA).

• There is a limit on the building's CO₂ emissions: an average of 7.1 kg CO₂e per m² per year.

• The construction process can emit a maximum of 1.5 kg CO₂e per m².

• The requirements apply when applying for a building permit.

• Limit values may vary depending on the type of building.

Certain critical buildings may be exempt from the requirements.
