Hardware Replacement Calculator

This little script enables you to see when it is worth replacing an old machine with a new one. We have prefilled a few example values. Feel free to adapt to your case. Read the full blog article here green-coding.io/blog/when-to-replace-a-machine

Accumulated Emissions Over the Years

Why does the new machine not start at 0 CO2eq?
Because we calculate the total emissions over time. If you would replace the old machine the emissions have still happened so we need to add them to the sum.
