Most hardware is retired because software outgrew it. Servers, laptops and phones get replaced when they feel slow. Not when they break. But making each new machine has a carbon cost. In twenty twenty-two, the world threw away sixty-two million tonnes of electronics. Here is the fix you can use today. First, set speed targets on the oldest hardware you support, not the newest. Then question every refresh cycle. Is a new machine needed, or just recommended? And make efficiency part of keeping hardware longer, guided by Germany's Blue Angel label. Take a server that took four tonnes of carbon to make. Over four years, that is one tonne a year. Keep it a fifth year, and it drops to eight hundred kilograms. The Green Software Foundation suggests keeping hardware in use for longer. That is because making it has a carbon cost. GreenCode treats the hardware your software needs as a quality measure. GreenCode helps tackle this by finding the code driving processor, memory and network demand. Then it rewrites it, so the same jobs run on the hardware you have.
