One Click LCA EPD & Product Carbon Footprint Software

One Click LCA Ltd is a Helsinki-based Finnish software company founded in 2001 that provides life cycle assessment tools for the built environment and manufacturing. It helps construction product manufacturers and project teams measure and reduce embodied carbon, which sits in the supply chain of materials rather than in building operations, and its software is used in more than 170 countries.

For manufacturers, the platform offers product LCA, cradle-to-grave product carbon footprints and an EPD generator that produces third-party verified EPDs with automated data collection, plus dedicated generators for concrete, luminaires and electronics. Calculations follow ISO 14040, ISO 14044, ISO 14067 and EN 15804 and draw on more than 500,000 LCA datasets. Sustainability intelligence modules track EPD usage and benchmark products, while building LCA tools connect to BIM and CAD. Manufacturer customers include ArcelorMittal, Kingspan, Geberit, Wienerberger and Uponor.

• Product LCA: full life cycle impact assessment with hotspot analysis and material comparison.
• EPD generator: third-party verified EPDs with automated data collection and regional standards.
• Product carbon footprint: cradle-to-grave emissions under ISO 14067 and EN 15804.
• Sector generators: dedicated EPD tools for concrete, luminaires and electronics.
• Sustainability intelligence: EPD usage analytics, specification tracking and product benchmarking.
• Global LCA database: more than 500,000 datasets with Excel, BIM, CAD and API import.

A Vietnamese steel, cement or tile producer can publish verified EPDs to meet CBAM and export buyer requirements. A building materials supplier can benchmark products to win specification in LEED or LOTUS projects. A developer or design consultant can calculate the embodied carbon of a project using supplier-specific data.

Manufacturers can create EPDs about ten times faster, cutting the process from months to days according to the company. Verified EPDs help products get specified in green building projects and meet CBAM, CPR and ESPR requirements. Case studies include Genuit reducing emissions by 45,000 tonnes, Blue Marble simplifying 5,500 components into 5 EPDs and Saudi Readymix scaling to 54 concrete EPDs.

Green building certification, the EU CBAM on steel, aluminium and cement, and procurement rules on embodied carbon are pushing building material makers to publish EPDs. Vietnam is a large exporter of steel, cement and building products and its green building market is expanding, supported by the Vietnam Green Building Council.

Founded in 2001 and headquartered at Sörnäistenkatu 1, Helsinki, Finland. Growth equity investors include PSG Equity and InfraVia Capital Partners. Authorised Vietnam reseller VILANDCO covers building LCA and EPD work. Committed to SBTi-aligned targets in March 2026 and named in the BuiltWorlds 2026 Building Tech Top 50.
