Sure. Two good sources are: 1. Life Cycle Assessment of Fairphone 4, showing an estimated 75% of energy use occurring during production and 16% during the lifetime of use: https://www.fairphone.com/wp-content/uploads/2022/07/Fairpho... 2. Eco profile of a 13.5" Surface Laptop 5, showing 85% of energy use occurring during production and 12% during the lifetime of use: https://www.microsoft.com/en-us/download/confirmat…
Still, I agree with you: design for efficiency and then mend and use efficiently.
