Imagine a product A with 0 CO2 but a huge animal suffering impact, B with huge CO2 but 0 suffering, and C with non-zero but tiny impact on both dimensions. Your weighting would favor C, while for any rational person either A or B (or both) would necessarily be preferable.
I think itās the other way around. Under a weighted product model (WPM), the overall impact of both A and B is zero because either component is zero, so the WPM favors A and B over C. Whereas summing the climate and welfare components (with āreasonableā weights) would result in C being the most favorable.

You were of course right; I now fixed the A B & C round to make them consistent. Thanks!
