The life cycle assessment shows that over a five year life span, production is responsible for 65% of CO2e, and usage about 25% (out of a total estimated 200kg - roughly 86L of gasoline) using "a typical US energy mix".
Component wise (during production), the largest CO2e contributor was the display at ~25%, then the mainboard at 20%, and then battery around 15%.
Take aways for me are that: from a sustainability standpoint, if you're going to buy new, then it makes sense to buy the most capable model that makes sense, and try to milk it for as long as possible. Also, I never would have guessed how high the impact of display production was. Certainly makes the harvesting of screens from dead laptops seem like a good option.
