NMD in short:
Category 1, 2 and 3 data. What are the differences?
In the National Environmental Database, we distinguish three categories of environmental declarations with environmental data: category 1, 2 and 3.
Category 1
Product- and brand-specific environmental declarations, typically submitted by manufacturers.
Verification: verified by an independent, qualified third party in accordance with the NMD Verification Protocol.
Transparency: environmental declaration is public; underlying environmental information has limited accessibility.
Category 2
Non-brand-specific data representing groups of manufacturers, suppliers and/or sectors.
Verification: verified by an independent, qualified third party in accordance with the Verification Protocol, including a statement on representativeness (e.g. representative for the Dutch market or a group of producers).
Transparency: environmental declaration is public; underlying environmental information has limited accessibility.
Category 3
Non-brand-specific data managed by Stichting Nationale Milieudatabase.
Verification: not verified in accordance with the Verification Protocol.
Transparency: environmental declarations and reference profiles are publicly available.
Category 3a
Non-brand-specific data managed by Stichting Nationale Milieudatabase. This includes data on infrastructure for external energy supply, energy carriers, and environmental declarations for fully reusable building elements and installations in new construction.
Verification: not verified in accordance with the Verification Protocol.
Transparency: environmental declarations and reference profiles are publicly available. The 30% surcharge factor does not apply.
To fill the National Environmental Database with as much category 1 and 2 data as possible, we encourage producers and manufacturers of building materials in supplying this data. We do this with a scheme under which you can be reimbursed €2,500 for having an LCA made. Click on the button below to read more about this ‘Filling the Gpas’ compensation scheme
