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:

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 product card 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 product card 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: product cards and basic profiles are public.

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.

Category 3 card reports

Since 1 June 2020, all new category 3 product cards are supplied with a report explaining the implemented LCA; the structure is described, including an explanation of the choices made. The LCA reports are divided across four files. An indication is given below of which chapters (based on the RAW chapters, which can be found in the functional descriptions (NL)) are included in which part:

 

  • PART 1: Various concrete items (Prefab paving and sewerage & Prefab omgekeerde T-liggers en druklaag); H11 Sloopwerken; H18 Baggerwerk; H22 Grondwerken; H23 Drainage; H24 Sleuf en sleufloze technieken; and H25 Pipes.
  • PART 2: H32 Beaconing; H33 Guardrails (steel bars); H34 Lighting; H36 Noise-reducing structures; and H47 Small-scale civil engineering structures.
  • PART 3: H41 Foundation structures; H42 Concrete structures; H43 Steel structures; and H44 Timber structures.
  • PART 4: H51 Greenery; H52 Coastal and riparian works; H53 Fendering and mooring works; H61 General construction work (wooden plank fences); H62 Traffic measures; H64 Flora and fauna provisions; H80 Foundation layers; H81 Bituminous surfaces; H82 Concrete surfaces; H83 Element surfaces; and H84 Special surfaces.
  • PART 5: H1000-8000 Processes; and rail track items.
