NMD Verification Protocol
All data included in the NMD after 1 January 2020, must be assessed based on the current NMD Review Protocol.
Independent verification of environmental data
To ensure the quality and reliability of the Dutch Environmental Database, Category 1 and Category 2 environmental declarations are independently verified before publication. The NMD Verification Protocol describes how this verification is carried out and the requirements that environmental declarations must meet.
The protocol is aligned with version 2.0 of the Assessment Method for Environmental Performance of Buildings and contributes to a consistent and transparent assessment of environmental data.
Who is it for?
The protocol is intended for:
- manufacturers and data owners
- LCA practitioners
- recognised LCA verifiers
- trade associations
What’s new in Version 2.0?
Version 2.0 has been updated to align with Version 2.0 of the Assessment Method for Environmental Performance of Buildings. Key changes include:
- alignment with EN 15804+A2
- application of the A2 environmental dataset
- updated assessment criteria and verification procedures
- clarification of roles and responsibilities
