Guide overview
From July 2025, BR18 requires that emissions from transport to site (A4) and construction activities on site (A5) are included in your LCA calculations, with a strict CO₂ limit of 1.5 kg CO₂e/m²/year for these stages alone.
To help you prepare, we’ve created this free Survival Guide in collaboration with Johanna Ida Jacobsen, DGNB-auditor and partner at Sustaining.
Whether you’re a contractor, developer, or sustainability consultant, this is your quick-start resource for tackling the new rules with clarity and confidence.
Want to skip the manual tracking and calculating? Acembee’s automated platform collects, optimises, and reports your A4 + A5 data for you, helping you stay within limits without the admin overload.
