Comparing the CO2e data - why Apple apparently so low? #2

Thanks for putting in the work to collate this. I've just come across the data and wondered why the Apple figures were so low. LCA and EEIO are notorious for using different operating assumptions and 'boundaries' and therefore making results non-comparable. Taking one Apple example - Macbook Air 13" (Retina, 2019) - the headline figure is 176kg but digging further into their PER (https://www.apple.com/environment/pdf/products/notebooks/13-inch_MacBookAir_w_Retina_PER_June2019.pdf) it appears they might be cherry-picking a little - the 1.8GHZ 256GB model is 361kg - more on a par with the Lenovo for example. Any thoughts?

(I'm a newbie to H so please forgive me any faux pas) thx

This is interesting, and is not something I picked up on when doing my initial research. Perhaps we should make the Apple CO2e a range if we have detailed data to do so?
