Environmental data
The National Environmental Database (NMD) contains environmental data of construction products and building installations – products supplied by industry – that are used in the calculation tools to calculate the environmental performance of construction works. The NMD’s environmental data contain environmental profiles: lists with environmental impacts expressed in various environmental impact categories in accordance with European standard (EN) 15804, such as the depletion of raw materials, global warming potential and ozone layer depletion.

Behind every environmental declaration is a Life Cycle Assessment (LCA). The NMD contains LCA data on construction products and processes, compiled according to strict methods and quality criteria.

If an LCA of your product has not yet been drawn up in accordance with the Assessment method, the first step is to have this analysis carried out by a (recognised) LCA practitioner of your choice.

Before the LCA practitioner can enter the environmental data, you must be registered as data owner with Stichting NMD. You then indicate that you agree to the NMD Terms of Use and the General Terms and Conditions. There are costs associated with registering data in the NMD. In order for invoicing to proceed in good order, we need billing details from you. It is also important that you indicate in the form which LCA practitioner will provide the data entry, so that login details for the entry module can be provided.
An LCA is a quantitative method to determine the total environmental impact across the product life cycle; from raw material extraction and production to end-of-life use and disposal. It allows companies to understand the environmental impact of their products and raw materials through the entire value chain. Read more information on environmental data here. Environmental declarations in the NMD must be prepared according to the The Environmental Performance Assessment Method for Construction Works (Assessment Method). Chapter 2 of the Assessment method provides the methodical requirements for determining the environmental performance of (building) products, installations and processes.
