Use of NMD Data
The National Environmental Database provides environmental data used in environmental performance calculations and other applications within the construction sector.
This page explains how this data is used, which topics are relevant to its application, and where to find more information to ensure it is used correctly.
The Dutch Environmental Database (NMD) contains environmental data used for environmental performance calculations of construction works. It also includes a Process Database with processes used in the development of life cycle assessments (LCAs) and environmental declarations. Published environmental declarations can be viewed through the NMD Viewer.
On this page, you can learn what the databases contain, how the classification system (Categories 1, 2 and 3) works, and where to go if you want to use, verify or register data.
Do you want to calculate or demonstrate the environmental performance of a construction project? The Dutch Environmental Database (NMD) is the authoritative source of uniform, validated environmental data.
NMD data is used by a wide range of professionals, including designers, consultants, public authorities and LCA practitioners. To apply this data correctly, it is important to understand the Assessment Method for Environmental Performance of Construction Works, the available calculation tools, and the structure of the data itself.
This page helps you quickly find the information you need.
