There are now many tools for using FDES and PEP, in particular for building LCA. As part of the RE2020 environmental regulation, some software has undergone an assessment of their compatibility with the E+C- experimentation reference system. This list is available on the E+C- experimentation site. As soon as RE2020 comes into force, this software (or new ones) has to be reassessed and validated to be in compliance with this regulation.
