Furniture Footprint Snapshot
A rapid estimate of embodied carbon for your interior specification
Petra AI estimates embodied carbon using:
Embodied Carbon = Mass × Material Carbon Intensity × Condition Factor
Material Carbon Intensities (kgCO₂e/kg):
Fabric Types:
Size Estimates:
Condition Factors:
Data Sources:
Limitations:
These are estimates based on industry averages. Actual values vary by specific material grades, manufacturing processes, transport distances, and refurbishment scope.
Circular Economy Context: This calculator focuses on keeping furniture and materials in use at their highest value through refurbishment, repair, and reuse – core principles from the Ellen MacArthur Foundation's circular economy framework.
