Classification	Class name : Hierarchy level EPDNorge: Construction
General comment on data set	Specific data for the product composition and production are provided by the manufacturer and are based on the production year 2024. The background data is taken from ecoinvent's database v. 3.10. For truck transportation (A4) background data is taken from the database Agri-footprint 4.0. The allocation is made in accordance with the provisions of EN 15804. Incoming energy and water and waste production inhouse is allocated equally among all products through mass allocation. Effects of primary production of recycled materials allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. All major raw materials and all the essential energy is included. The production process for raw materials and energy flows that are included with very small amounts (<1%) are not included. This cut-off rule does not apply for hazardous materials and substances.

¹This impact category deals mainly with the eventual impact of low dose ionizing radiation on human health of the nuclear fuel cycle. It does not consider effects due to possible nuclear accidents, occupational exposure nor due to radioactive waste disposal in underground facilities. Potential ionizing radiation from the soil, from radon and from some construction materials is also not measured by this indicator.
²The results of this environmental impact indicator shall be used with care as the uncertainties on these results are high or as there is limited experiences with the indicator.
