Concrete Embodied Carbon Calculator

Clinker reduction & SCM savings estimator

kg CO₂e / m³

Mix inputs

Concrete volume 100 m³

Cementitious content 350 kg/m³

Baseline clinker emission factor 900 kg CO₂e/t

Typical Portland clinker range: ~800–950 kg CO₂e per tonne of clinker (project/EPD data will vary).

Replacement material

SCM replacement 45%

SCM emission factor 210 kg/t

Presets set typical starting values — edit both sliders to match your own mix design or EPD data.
