Embodied carbon is the greenhouse-gas footprint of making a construction material, measured in kgCO2e (kilogrammes of CO2 equivalent). This calculator follows the standard product-stage method used by RICS, LETI and EN 15978/EN 15804: cradle-to-gate (life-cycle modules A1–A3) carbon = material quantity × carbon factor.
Carbon Footprint Calculator UK Construction: The carbon footprint of constructionin the UK encompasses both the embodied carbonlocked into the materials used to construct a building and the operational carbonemitted during the building's lifetime through heating, cooling, lighting, and ventilation. In 2026, as the UK construction industry works towards its net-zero commitments under the ...
The CIBSE Embodied Carbon Calculator: United Kingdom complements the CIBSE publication Embodied carbon in building services: a calculation methodology (TM65), and is intended to support consultants, researchers and manufacturers in assessing the embodied carbon of building services equipment where no environmental product declaration is available.
Select values on the left to display your embodied carbon calculation. Please note that these values will be used by CIBSE to create an Embodied Carbon Database.
Planetary is a free-to-use, global embodied carbon software that helps you calculate and benchmark the embodied carbon impact of your building designs.
• In the building industry, embodied carbon refers to the greenhouse gas emissions arising from the manufacturing, transportation, installation, maintenance, and disposal of building materials.
Calculate embodied carbon for UK structural steel by production route. UK average, BF-BOF, EAF scrap, Xcarb and reused steel factors from SCI P449 and BCSA.
Embodied carbon calculator INTRODUCTION We are very pleased to make available a spreadsheet for calculating the embodied carbon of façade systems. This has been produced in collaboration with WSP, and we are very grateful for all of their support throughout this process.
The Structure Workshop Carbon Calculator references industry standard carbon factors, sourced from Bath University's ICE database, and generates embodied carbon figures (kgC0₂e) for all stages of the project life cycle. We believe we can have a more positive impact by sharing knowledge and have made our carbon calculator freely available.
