The MKI expresses the environmental impact of materials, products and works in euros. Here is what it is, how it relates to the MPG, and where each statement comes from.
The MKI (milieukostenindicator) expresses the environmental impact of materials, products and works in euros, based on a life cycle analysis. The NMD uses it for civil engineering works (GWW), with the same determination method that sits behind the MPG for buildings.
The NMD describes the MKI for civil works, where the result is given in euros. For buildings the same method gives the MPG, in euro per m2 of gross floor area per year. Whether a given tender requires an MKI is something its documents state.
Modou reads the documents in a tender package (PDF, DOCX, XLSX, CSV, IFC2x3, IFC4 and DXF) and lists where they name an MKI requirement. Nothing more. Modou is still in development.

Milieukostenindicator, in English environmental cost indicator. According to the NMD it expresses the environmental impact of materials, products and works in euros, based on a life cycle analysis.
The NMD uses the same method for both. The MKI is expressed in euros and is used for civil works. The MPG is the buildings variant, in euro per m2 of gross floor area per year.
According to the NMD, from 1 July 2026 there are 19 impact categories under EN 15804+A2, and a new set of weighting factors applies.

No. Modou does not calculate the MKI and shows no MKI figure. It reads the documents in a tender package and lists where they name an MKI requirement.
