Multi-country comparison
The same product, register by register
Published EN 15804 declarations for one product type, side by side across the open national registers. Each figure is shown with the declared unit and the life-cycle module the declaration states. Declarations with different declared units are never converted or averaged — read them as separate products, not as a ranking.
Declarations differ in declared unit, reference service life, background data and the version of EN 15804 they follow. A lower number in one register does not by itself mean a lower-impact product. Always read the declaration behind the figure.
