  • Integrating sustainability into remediation projects has
    attracted attention from remediation practitioners, and life
    cycle assessment (LCA) is becoming a popular tool to address
    the environmental dimension. The total number of studies has
    reached 31 since the first framework for LCA of site remediation
    was published in 1999,1 and has almost doubled compared to
    number of studies in two reviews published in 2010.2,3 However,
    our analysis shows an increasing frequency of examples with
    serious methodological problems (compared to requirements in
    ISO standards or authoritative guidelines). Figure 1 shows that
    numerous studies have no or an incomplete definition of the
    functional unit, omit an appropriate quantification of primary
    impacts, or fail to include all relevant secondary impact
    categories. We will illustrate how ignoring these methodological
    challenges can lead to a misleading conclusion about the
    environmental sustainability of remediation technologies.
