Surely critical here is the choice of assumptions for LCAs and then the regular reassessment of those on a regular basis (and the re-evaluation of LCAs if changes call for it)?
When it comes to assumptions, one should check their impact through what's called a Sensitivity Analysis: seeing the effect if those assumptions were to be different. If changing the assumptions dramatically change the conclussions, we should be very weary of those conclusions. That's why at Earthster we make sensitivity analysis as easy as changing a few numbers, and you immediately see the effects.
