E-waste Calculator
What trading in a device saves, in materials and in carbon.
What this is
A calculator that turns "I traded in an old phone" into numbers: the carbon not emitted by manufacturing a new one, and the materials not mined for it.
Why it exists
Electrical waste is one of the fastest-growing waste streams in the world, and most of it is not waste at all — it is working equipment in a drawer. Selling a device you have stopped using is the single most useful thing you can do with it.

Until the calculator is live, trading a device in still does the same work. Start at the trade-in page.
