Register your product in the Dutch Environmental Database
Would you like to have an environmental declaration for your product registered in the Dutch Environmental Database? You will then follow a fixed admission procedure. This process safeguards quality, transparency and independent review of environmental data. On this page you can read which steps to take, who is responsible for which role and what is required to have your product included in the database.
The environmental performance of construction works provides insight into the environmental impact of a building or civil engineering work throughout its entire life cycle. The environmental performance is determined on the basis of a uniform calculation method and environmental data of construction products. The outcome makes differences between design and material choices transparent and comparable. In the building sector this is expressed as the Environmental Performance of Buildings, and in the civil engineering sector often as the Environmental Cost Indicator. Is this topic new to you?

Step-by-step guide: how the process works
Registering data always follows a fixed procedure:
- Conduct a life cycle assessment (LCA)
An LCA maps the environmental impact of your product throughout its entire life cycle. If you cannot do this yourself, engage a (recognised) LCA practitioner to prepare this analysis correctly. - Register as a data owner
The producer (or industry organisation) registers with Stichting NMD as the data owner. This is required for billing and to be formally responsible for the environmental declaration. - Enter environmental data
The LCA practitioner enters the environmental data via the NMD input portal. The practitioner needs their own input account for this. The data is entered based on the environmental declaration resulting from the LCA. - Review by a recognised LCA reviewer
A recognised, independent LCA reviewer checks whether the data complies with NMD protocols. - Publication in the Dutch Environmental Database
After approval, Stichting NMD publishes the environmental declaration.
From that moment on, your product can be included in validated environmental performance calculations (WLC-GWP/MKI).

Do you want to register your product?
Are you a producer or supplier? Then you are the data owner.
Do you create or perform the LCA? Then you are the LCA practitioner.
Support: Compensation scheme Filling the Gaps
Commissioning an LCA involves costs. For certain product groups, financial support is available. With the compensation scheme Filling the Gaps, Stichting NMD lowers the threshold for having an environmental declaration prepared.
Frequently asked questions environmental data
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.

Or check the list of companies that draw up LCA practitioners. These companies are mostly affiliated with the VLCA.
Have you found an LCA practitioner? Then see the next steps here
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.
