Environmental data
Environmental data form the basis for calculating the environmental performance of construction works. These data are based on a life cycle assessment of a construction product or process and are recorded in an environmental declaration. Within the Dutch Environmental Database, environmental data are reviewed and registered before being applied in environmental performance calculations.
Environmental data in the Dutch Environmental Database are based on life cycle assessments of construction products and processes. The results of an LCA are recorded in an environmental declaration. These environmental declarations are used in environmental performance calculations of construction works. On this page you will find information about compiling, reviewing and registering LCA data and environmental declarations within the framework of the Dutch Environmental Database. Go to From LCA to environmental declaration in short for a brief introduction.
What is environmental data?
Environmental data describe the environmental effects of a construction product or process across its full life cycle. This data is collected in a life cycle assessment (LCA) and recorded in an environmental declaration. Within the Dutch Environmental Database, this data is registered and managed according to fixed quality protocols.
Are you a producer, data owner or LCA consultant? Below you'll find the relevant information about your role in the process.
For producers and data owners
Would you like to have an environmental declaration registered for your product... or do you already manage an existing registration? On this page you can read what an environmental declaration involves, how environmental data is compiled, and how registration and management within the NMD work.
For LCA consultants and recognised LCA experts
Do you compile a life cycle assessment or review environmental data? Here you'll find information on entry, review protocols and quality requirements.
How is environmental data structured?
Environmental data in the Dutch Environmental Database is structured from separate environmental impact categories. Read more about the structure and classification of these impact categories on the page Environmental impact categories.
What is a life cycle assessment (LCA)?
A life cycle assessment calculates the environmental impact of a construction product across its full life cycle and forms the basis for environmental data in the Dutch Environmental Database.

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.
