Carbon footprints for various developer-friendly laptops (notebook computers).
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
I first want to thank you for putting in the work to organise the values in such a way. I just had a quick question about the given values for the used carbon footprints are for a 4-year lifecycle. What are the assumptions for the usage of the laptop in those 4 years? Is it 8 hours a day for 5 days a week? or how many hours is it?
