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.

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.

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.
