Everything releases carbon in its creation and will also release carbon in its destruction. That includes computing devices. By the time a person buys a computer, it's already emitted more carbon than it will ever emit through its consumption of electricity. That's "embodied carbon". Computers don't wear out. They become obsolete because developers are constantly creating software that pushes the limits of hardware. A solution? Write much more efficient code and reducing unnecessary features of applications. Principle 4: Embodied carbon - Learn | Microsoft Docs.
