This Technical Report (TR) has been developed by CEN/TC 350/WG 1 and WG 3 to provide a clear and structured view on the relevance, robustness and applicability of a predefined set of additional impact categories and related indicators for the assessment of the environmental performance of construction works, construction products and building materials.
The TR describes the evaluation criteria that are used to determine, for these impact categories, the suitability of indicators and calculation method(s) for inclusion in the standards EN 15978 and EN 15804 (or other CEN/TC 350 standards as appropriate) in terms of their:
a) relevance to:
1) the environment,
2) construction works,
3) construction products, and
4) EU policy;
b) scientific robustness and certainty; and
c) applicability of the impact assessment method(s).
The additional impact categories examined in the TR are:
— human toxicity and ecotoxicity;
— particulate matter;
— land use;
— biodiversity;
— water scarcity; and
— ionizing radiation.
