LCAx

The goal for LCAx is to make an open, machine and human-readable data format for exchanging LCA results, EPD's and assemblies.

We propose a simple three level data format with information on project, assembly and EPD level, written in an open data format and paired with a validator for a more robust and standardized format. We intend to create connections to existing tools and API’s.

Our goal is making LCA calculations more accessible, transparent, and open.
