Dutch Environmental Database
The Dutch Environmental Database (NMD) is filled with product cards 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 a product card should contain when this is entered into the NMD.
Product card categories
A product card 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 card for a new product from the consumer or other market, the NMD can approach the market to draw up a specific product card. Another option is that, following an internal procedure, the NMD decides to create a non-proprietary (category 3) card for a new product. The NMD distinguishes three product card categories:
Product card validity
The database uses a periodic product card expiry date of five years. Product cards must be amended after this period. The product cards 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 product cards themselves via an online input application.
