One Click LCA

One Click LCA is the leading life cycle assessment platform for the built environment, used by architects, engineers, contractors and developers to calculate and reduce embodied and operational carbon across a building’s full lifecycle. With over 250,000 verified material datasets and compliance with more than 80 international certifications, it has become the default tool for studios that need to demonstrate whole life carbon performance to clients, planners or certifiers.

For UK studios specifically, One Click LCA holds first-place validation under the RICS Whole Life Carbon Assessment standard (2nd edition) and is approved by BRE for BREEAM New Construction Version 7 assessments. As the UK Net Zero Carbon Buildings Standard moves toward mandatory adoption, having an RICS-validated workflow in place is fast becoming a baseline expectation rather than a differentiator. Studios can run assessments aligned with RIBA 2030 Climate Challenge targets from early design stage through to completion.

BIM integration is a core part of the workflow. The platform connects directly with Revit, ArchiCAD, Tekla, and accepts IFC files, meaning quantity takeoffs from the model feed straight into the LCA calculation without manual re-entry. The Carbon Designer 3D tool allows early-stage carbon optimisation before detailed design is committed. For studios not yet on full BIM, data can also be entered via spreadsheet or the browser tool directly.

One Click LCA is not a tool most studios will use daily, but for practices doing BREEAM-rated, planning-sensitive, or net zero committed projects, it is increasingly the required standard. Its database depth and RICS validation make it the most defensible choice when a carbon assessment needs to stand up to scrutiny.
