Environmental Assessment of Emerging Technologies - Recommendations for Prospective LCA
Artikel i vetenskaplig tidskrift, 2018

The challenge of assessing emerging technologies with life cycle assessment (LCA) has been

increasingly discussed in the LCA field. In this article, we propose a definition of prospective

LCA: An LCA is prospective when the (emerging) technology studied is in an early phase

of development (e.g., small-scale production), but the technology is modeled at a future,

more-developed phase (e.g., large-scale production). Methodological choices in prospective

LCA must be adapted to reflect this goal of assessing environmental impacts of emerging

technologies, which deviates from the typical goals of conventional LCA studies. The aim of

the article is to provide a number of recommendations for how to conduct such prospective

assessments in a relevant manner. The recommendations are based on a detailed review of

selected prospective LCA case studies, mainly from the areas of nanomaterials, biomaterials,

and energy technologies.We find that it is important to include technology alternatives that

are relevant for the future in prospective LCA studies. Predictive scenarios and scenario

ranges are two general approaches to prospective inventory modeling of both foreground

and background systems. Many different data sources are available for prospective modeling

of the foreground system: scientific articles; patents; expert interviews; unpublished experimental

data; and process modeling. However, we caution against temporal mismatches

between foreground and background systems, and recommend that foreground and background

system impacts be reported separately in order to increase the usefulness of the

results in other prospective studies.
