Why include your environmental declaration in the environmental database?
To determine the sustainability of a structure, environmental performance is an important measure. The better the environmental performance of a structure, the lower its environmental impact. The calculation tools used to calculate environmental performance get their information from the information stored in the National Environmental Database.

As a manufacturer/producer, there are advantages to having a life cycle assessment performed for your product and having it included in the environmental database.
- Insight into the production chain
A life cycle analysis (LCA) gives you valuable information about the environmental impact of your product and the production process. This insight helps you improve your business operations and make them more sustainable.
- Access for MPG/MKI projects and calculation tools
Is your product included in the environmental database? Then it becomes visible to sustainability professionals who calculate with EPB and ECI tools. This increases the chance that your product will be used in sustainable building projects.
- Transparant and future-oriented
The requirements for environmental performance calculations will be further tightened in the coming years. Products with approved, testable environmental data (category 1 or 2 data) will soon be essential. By starting now with an LCA, you are prepared and prevent delays.
- Possibility for compensation
Thdough the Filling the Gaps compensation scheme NMD Foundation stimulates completion of missing, verfied environmental data in the NMD. The compensation scheme rins until November 1, 2025 (as long as places are available) and is intended for manufracturers, suppliers, startups and indusrty ogranizations, among others.
