One Click LCA is a sustainability platform that helps architecture, engineering, construction, and manufacturing teams measure and reduce environmental impacts. It supports life-cycle assessments, embodied carbon calculations, whole-building analysis, product comparisons, and regulatory reporting.
By connecting design data with extensive environmental databases, One Click LCA helps users evaluate alternatives, meet certification requirements, and make informed low-carbon decisions throughout project development.
One Click LCA is the world’s leading end‑to‑end sustainability platform, purpose-built for the construction and manufacturing sectors. Founded in Helsinki in 2001, the company has grown to a team of over 200 professionals across all continents and now serves users in more than 170 countries
At its core, this cloud‑based platform offers streamlined, automated Life Cycle Assessment (LCA) and Environmental Product Declarations (EPDs), enabling users to scientifically measure and reduce environmental impacts of structures, infrastructure, renovations, and manufactured goods. Beyond LCA and EPDs, it also supports assessments of circularity, life‑cycle cost, and biodiversity.
A standout feature is its extensive global database with over 250,000–300,000 datasets—covering supplier-specific and generic material data—fully verified and regularly updated. This empowers users to make informed, data‑driven decisions. The platform supports over 80 compliance standards, including LEED, BREEAM, GRESB, CALGreen, and various country‑specific regulations.
One Click LCA seamlessly integrates with more than 20 leading BIM and design tools, such as Autodesk Revit, Tekla Structures, Bentley iTwin, Rhino, and Grasshopper. This allows for real‑time feedback and early‑phase embodied carbon optimization—notably through its Carbon Designer 3D tool, which enables quick, BIM‑integrated carbon hotspot analysis and comparison of design scenarios. In some cases, Carbon Designer 3D helps identify carbon footprint variations up to 50% during conceptual design.
Leading global players—including Skanska, WSP, Foster+Partners, Turner, ArcelorMittal, Arcadis, ARUP, Geberit, and Saint‑Gobain, among others—rely on One Click LCA to drive their decarbonization efforts. AECOM, for instance, equipped its ScopeX™ platform with One Click LCA to target a 50% carbon reduction across its projects.
Its visibility among industry analysts reflects its market leadership: One Click LCA was featured in Verdantix’s 2025 Buyer’s Guide for LCA tools and is the first platform validated by RICS under its Whole Life Carbon Assessment (WLCA) programme.
One Click LCA also makes parts of its platform freely accessible via its Planetary embodied–carbon calculator—a tool for benchmarking cradle‑to‑gate carbon impacts across building designs and supporting EPD usage worldwide. In summary, One Click LCA stands out with its:
- Massive, high-quality global dataset (250–300k records)
- Broad compliance across 80+ standards
- Deep BIM integrations for early and ongoing carbon management
- Recognition by major firms and standards bodies
It remains the go-to platform for turning sustainability goals into measurable, actionable outcomes across construction and manufacturing value chains.
