“…Therefore, it should be noted that as a result of the diversity of the methodologies used in the case studies and literature, the individual cases cannot be used to quantify reductions in general, but instead, illustrate the potential of different reduction strategies in various contexts.

“…For the first category, a number of case studies demonstrate that substitution with bio-based materials will reduce EEG due to the low-energy production methods (Nakao et al, 2011, Brown., 2013, Wallhagen et al, 2011, Monahan and Powell., 2011, Vukotic et al, 2011, Darby et al, 2013. Substitution of timber in large building components has a relatively high potential to reduce embodied greenhouse gas emissions.…”

Building-related embodied impacts are growing and should not be ignored.  Ways of improving transparency in embodied impact assessments are proposed.  Actor-specific guidelines can foster integration of embodied impacts into practice.  The availability of quality-checked databases can support the entire process.  A number of strategies for the reduction of embodied impacts are demonstrated.

“…There are studies looking at differences in emissions of greenhouse gases and energy use for buildings using different structural alternatives (e.g. concrete and wood) (Brown, 2013). The results here suggest that it would be interesting to include NORM exposure in these assessments.…”

The potential impact of ionising radiation from enhanced exposure to Naturally Occurring Radioactive Materials (NORM) to humans and the environment is not currently accounted for sufficiently in Life Cycle Assessment (LCA). Here we present midpoint and endpoint characterisation factors resulting from the implementation of impact assessment models for human health and ecosystems for NORM exposure. These models build upon existing fate, exposure and effect models from the LCA and radiological literature. The newly developed models are applied to a theoretical study of the utilisation of bauxite residue, a by-product of alumina processing enriched in natural radionuclides, in building materials. The ecosystem models have significant sensitivity to uncertainties surrounding the differential environmental fate of parent and daughter radionuclides that are produced as a part of decay chains, and to assumptions regarding long term releases from landfill sites. However, conservative results for environmental exposure suggest that in addition to landfill of materials, power consumption (burning coal and mining uranium) is a potentially significant source of radiological impact to the environment. From a human perspective, exposure to NORM in the use phase of building materials is the dominant source of impact, with environmental releases of nuclides playing a comparatively minor role. At an endpoint level, the impact of NORM exposure is highly significant in comparison to other impact categories in the area of protection of human health.The dose increase is of an order of magnitude comparable to lifestyle factors. The results highlight the importance within LCA of having sufficient impact assessment models to capture all potential impacts, such that issues of burden shifting between impact measures can be captured, interpreted and resolved in the optimisation of product systems. Highlights A new life cycle impact assessment model for exposure to NORM is presented  Midpoint and endpoint characterisation factors for humans and ecosystems are given  The models are validated with respect to bauxite residue valorisation systems  The importance of burden shifting within life cycle impact assessment is raised
