Databases

The Stichting NMD databases contain environmental data that are used to calculate the environmental performance of construction works. As well as the background process and basic profile database used by Life Cycle Assessment (LCA) practitioners, there’s also an environmental declaration database that we call the National Environmental Database (NMD).

The National Environmental Database contains environmental data used to calculate the environmental performance of construction works. The NMD process database is a collection of specific and generic environmental processes and semi-finished products used in LCAs, such as material production, waste processing, transport, and energy generation. From the databases and environmental profiles to information about data admission: explore how the database is structured and how to work with it.

Frequently asked questions about the Database

What is the difference between the National Environmental Database and the process database?

Stichting NMD manages both the National Environmental Database (NMD) as well as the NMD Process Database. The NMD is a database filled with environmental declarations. This is the database that is used by the calculation tools to produce ECI and EPD calculations. The NMD Process Database is used as source (to draw up LCAs) for the data included in the environmental declarations in the NMD.

What is the validity of my environmental declarations and/or baseline profiles?

The environmental declarations and basic profiles should be reviewed for timeliness from time to time and then updated as necessary. The same shelf life applies to both with a periodic expiration date of 5 years. After this period, environmental declarations and basic profiles must be updated. This can also be done in the interim, for example after changes in the production process that affect environmental performance. Data owners can have their data changed by submitting a new template.

What is a background process?

A background process is a process that affects a producer's or supplier's product, but over which the producer or supplier has no direct influence and which occurs elsewhere in the chain; for example, production of electricity or a raw material.
