Category 3 data
In the National Environmental Database, there are three categories of environmental declarations. Besides the tested category 1 and 2 environmental declarations, there is a third category; proprietary data from NMD Foundation. The proprietary data of category 3 declarations are compiled by experts based on international databases and they contain so-called default values (safe values). Because the data is untested, these statements receive a 30% surcharge.
