Opt for manual entry of building materials and data, or swiftly import designs from Excel, Autodesk Revit, Rhino, Procore, IFC, IES-VE, energy models (gbXML), among others. Input options also include building areas, energy and water usage, site operations, emissions, and removals for a comprehensive life-cycle impact assessment of your building.

Reliable & compliant EPDs

One Click LCA solution balances affordability with quality. The tool meets global LCA and EPD standards like ISO 21930, ISO 14044, ISO 14025, ISO 14067, and EN 15804, including its recent updates.

Compliance with EN 15804+A2

We ensure your EPDs comply with the latest requirements of EN 15804+A2, a crucial global standard for EPDs, effective from July 2022.

EPDs aligned with global standards

With One Click LCA Pre-verified EPD Generator, all results categories are calculated automatically from your input data in line with EN 15804+A2, EN 15804+A1, and TRACI 2.1. This means your EPD has global passporting rights for its whole five-year validity. One Click LCA EPD tools also support the ISO 14067 requirement to report fossil and biogenic carbon emissions, land-use change emissions, and carbon storage separately. This requires using the software in line with EN 15804.

Critical third-party verification

ISO 14025 emphasizes the importance of third-party verification for EPD reliability. This step is crucial for your EPD's recognition in certifications, regulations, and procurement standards, distinguishing it from unverified EPDs.

Will it help me to comply with EN 15804+A2?

Why is third-party verification necessary?

Third-party verification is a key factor in why EPDs are valued for their impartial, standardized, and comparable information. It is a core element of the international standard that defines EPDs: ISO 14025. Without third-party verification, your EPD will not be recognized by many certification schemes, regulations, and procurement requirements. Bypassing third-party verification may seem attractive in the short term, but in the long run, it could render your EPD investment effectively useless.

Do I need to publish my EPD?

No, you can choose not to publish by creating a private EPD for tendering use only. Publishing is required for public EPDs and our team will support you through the process. You can benefit from lower EPD publishing rates with our Pre-verified EPD Generator.
