Dutch Environmental Database
The Dutch Environmental Database (NMD) is filled with environmental declarations that contain general information about products, including name, service life and functional unit. They also contain environmental information that has been obtained via a Life Cycle Assessment (LCA). The Assessment Method states which environmental information an environmental declaration should contain when this is entered into the NMD.
Environmental declarations in the NMD can be viewed via the viewer and can be used in validated calculation tools.
Environmental declaration categories
An environmental declaration with environmental information is contained in the NMD for all products potentially present in the reference buildings according to the energy performance regulation (BENG). If a need is identified for a declaration for a new product from the consumer or other market, the NMD can approach the market to draw up a specific environmental declaration. Another option is that, following an internal procedure, the NMD decides to create a non-proprietary (category 3) declaration for a new product. The NMD distinguishes three environmental declaration categories:
Category 1
Proprietary data from manufacturers and suppliers. Verification: verified by an independent, qualified third party in accordance with the NMD Verification protocol. Public access: the environmantal declaration is public, environmental information has restricted access.
Category 2
Non-proprietary data from groups of manufacturers and/or suppliers and sectors. Verification: verified by an independent, qualified third party in accordance with the Verification protocol, stating how representative it is, for example, for the Dutch Market or a group of producers. Public access: the environmental declaration is public, environmental information has restricted access.
Category 3
Non-proprietary data from Stichting National Environmental Database. Verification: not verified according to the Verification protocol. Public access: environmental declarations and basic profiles are public.
Categorie 3a
Proprietary data (unbranded) from National Environmental Database Foundation. Data from infrastructure for external energy supply, energy carriers and product maps of building elements/installations to be reused in their entirety in newly built structures. Review: not reviewed according to the Review Protocol. Publicity: environmental declarations and basic profiles public. 30% uplift factor not applicable.
Environmental declaration validity
The database uses a periodic environmental declaration expiry date of five years. Environmental declarations must be amended after this period. The environmental declarations can also be edited in the interim by the data supplier, for example after a change in production process that impacts environmental performance. Data owners can enter and edit environmental declarations themselves via an online input application.
