About One Click LCA

The AI-powered sustainability platform for construction & manufacturing.

Powering the makers of a zero-carbon future

Founded in 2001, One Click LCA is the world-leading end-to-end sustainability platform for construction and manufacturing. The AI-powered software platform decarbonizes and drives sustainability across the construction value chain with scientific, easy-to-use, automated life cycle assessment (LCA) and environmental product declarations (EPDs) to calculate and reduce the environmental impacts of building, infrastructure, and renovation projects and products. The platform also allows assessment of circularity, life cycle cost, and biodiversity. The One Click LCA group also includes SimaPro, a widely used life cycle assessment software, and PRé Sustainability, providing consulting services.

One Click LCA's work in the United Kingdom

One Click LCA supports the UK's built environment across major compliance requirements, including BRE-approved BREEAM Version 7 calculations with maximum credits under Mat 01 and Mat 02, RICS Whole Life Carbon Assessment Standard v2, and alignment with the GLA London Plan and the UK Net Zero Carbon Buildings Standard. The platform also integrates the Future Homes Hub's default carbon data for new homes and partners with the UK Green Building Council.

One Click LCA shares life cycle data with trade organisations such as Timber Development UK, the Electrical Distributors' Association, the Mineral Products Association, and others, to support data accuracy.
