The building sector has seen recent growth in the number of published environmental product declarations (EPDs). EPDs share environmental data of construction materials, which can help building practitioners prioritize products with lower environmental impacts. However, EPDs rely on varying assumptions within their life cycle assessment (LCA). This study aimed to evaluate the use of EPDs as a data source instead of a generic data source and its effect on the life cycle impacts of a multi-residential building. This study focused on 19 North American EPDs of structural wood products. The impact assessment results found in the EPDs were compared to the Ecoinvent V3.8 database. The findings of the present study suggest that EPDs can generally be used without distinction compared to the data in the Ecoinvent V3.8 database. However, a few data were found to be outliers. In addition, EPDs of structural wood products only disclosed its manufacturing stage. Other life cycle stages, such as transport of the construction product, can have a significant impact on the building’s LCA. Therefore, using EPDs to assess building impacts is recommended over their direct comparison for practitioners to make more comprehensive decisions towards embodied impacts of buildings.

To shift toward a bio-based and circular economy, wood is seen as a key component. To assess the environmental impact of wood utilization, life cycle assessment (LCA) is used. However, current LCAs lack comparability. To be comparable, LCAs must be reproducible, transparent, and follow the same approach. Hence, the goal of the study is to identify the level of harmonization among state-of-the-art LCA applications within the woodworking sector via a comprehensive systematic literature review. The results show that LCA has been applied to various products and processes in the woodworking sector and highlight the predominance of the construction sector. Examining the different LCA phases, different approaches and policies are identified. Recommendations are presented on how LCAs for the woodworking sector can be streamlined. This involves general recommendations for LCA practitioners and policymakers to have at least a cradle-to-grave approach, a standardization of the background and the technical backbone of the foreground system, a harmonized impact assessment method, and performing a sensitivity analysis for the interpretation of the results. For woodworking specifically, temporal, and spatial considerations, accounting for timing of emissions and land use (change), should be included as well as proper End-of-Life considerations via a cascading approach. The increased adoption of wood as a clean technology offers a promising environmental performance; particularly, if forests are sustainably managed, wood modifications are non-fossil and non-toxic, and circular strategies are incorporated. To fully realize its potential, it is essential to standardize LCA methodologies which can set an example to support regulatory policies. Graphical abstract
