MacBook Air owner?

2018/2019 models are losing #Apple support.

#OptGreen with #GNU/#Linux to keep your device in use! These machines will run beautifully for many years to come.

Not only wallet friendly, #upcycling keeps CO2 emissions out of the atmosphere. Ca. 75% of Apple’s emissions comes from production alone (details in alt text).

    Anyone knows how the usage is being estimated? What is the expected lifespan and how does one come up with a carbon budget there?

      @phoenix It looks to be statistical inference based on sampled and modelled data. On p. 57 of the report: “To model customer use, we measure the power consumed by a product while it is running in a simulated scenario. Daily usage patterns are specific to each product and are a mixture of actual and modeled customer use data.”

      The number of devices for the statistical inferences is: “In fiscal year 2018, we sold 217,722,000 iPhone devices, 43,535,000 iPad units, and 18,209,000 Mac products.”

      @phoenix Regarding the assumed operating life of devices:

      “For the purposes of our assessment, years of use, which are based on first owners, are modeled to be four years for macOS and tvOS devices and three years for iOS and watchOS devices. Most Apple products last longer and are passed along, resold, or returned to Apple by the first owner for others to use.”

      Hope that helps!

        Thank you, that sheds some light onto it, yes. I’m still wondering how this number marches up. Just using the device by far uses not even comparable amount of energy than e.g. the production and then it also depends if you use green energy or a diesel generator in your backyard.

        Not sure how to read this.
