    Environmental impact data using life cycle analysis (LCA) often do not include measures of variance, and therefore the reviewed studies did not provide confidence intervals for environmental impacts.

    this is exactly my problem with poore-nemecek 2018. this analysis, unlike poore-nemecek, admits that it’s a major gap in the methodology, but still suffers from this gap.
