Embodied Carbon & ESG for Construction (2026)
Why it matters now
From 2026 the EU CSRD (Corporate Sustainability Reporting Directive) and EU Taxonomy force contractors and developers to report embodied carbon (A1–A5 life-cycle modules), not just operational energy. Estimators need carbon numbers next to price numbers at the BOQ line level.
Method
Carbon = quantity × carbon factor, applied per material resource line — exactly parallel to quantity × unit price = cost.
work item → components[] → material lines → quantity × EF (kg CO₂e / unit) → line carbon
BOQ roll-up: Σ line carbon = project embodied carbon (A1–A3) + transport/waste (A4–A5)
