Concrete in the built environment

What is new

A controlled platform renewal, not a feature release.

The familiar workflow stays. Underneath it, a new calculation engine, updated methodological content and digitally connected outputs.

openLCA at the coreEngine
A stronger, more transparent and scalable calculation engine, and the technical basis for digital integration and future system connections.
GCCA GNR 2023 dataSector data
The latest industry dataset, collected to the CO₂ and Energy Accounting and Reporting Standard for the Cement Industry.
Latest cement PCRNorth America
Incorporates the current North American Product Category Rules for Portland, blended, masonry, mortar and plastic cements.
Pre-verified toolVerification
Version 6 is listed as a pre-verified LCA tool by the International EPD® System, so EPDs calculated with it follow the simplified verification route and the verifier checks your data rather than the model.

Improved modelling

Material propertiesMore detailed material properties and updated background data.
Electricity by voltageLow, medium and high voltage electricity modelled separately.
Mixing trucksElectricity inputs for mixing trucks are now captured.
Construction electricityRegionalised electricity data for construction-stage activities.
RecarbonationRefined calculation logic for concrete recarbonation in use.
ArchitectureUpdated for system connections and digital workflows.

For existing users

Your login has not changed.

01Log in as usual at tool.gccaepd.org with your current username and password.

02Parallel running. The previous version and Version 6 run side by side for six months, so work in progress can be finished where it started. You can still log in to Version 5.2 at concrete-epd-tool.org.

03Expect some result changes. Updated data, PCRs and modelling detail mean results for the same inputs may differ from Version 5.2.

04Read the documentation. Updated user guide, LCA model report, database and verification reports are in the documentation library.

Why it matters now

EPDs are becoming regulated, machine-readable product data.

ISO 14025:2026Published
The second edition sets explicit requirements for EPD tools and their independent verification, and tightens impartiality rules. The tool you calculate with matters.
Revised EU CPRIn force
Regulation (EU) 2024/3110 provides for environmental performance and digital construction product information, with detail following in delegated acts.
Digital product dataDeveloping
Procurement, ratings and building LCA increasingly need structured data. Version 6 is built to feed those systems, through ILCD+EPD and the API.
