I don’t have the current knowledge nor the time to reach the level of researchers in the domain to make my own meta analysis. Where can I read a reputable rebuttal to this meta analysis?
you can read the sources that poore-nemecek cite. they are explicit that their research cannot be combined with other LCAs
I am skeptical that researchers and reviewers of Science wouldn’t have accounted for that. I made some research about rebuttal to this study, so far the only ones I have found are from farmer related or anti-vegan communities, which are likely more biased than a scientific journal. I will need at least a contradictory peer reviewed article to convince me this meta analysis is incorrect.
