If microsoft can do it, why not google? They have a vendor qualification process that includes a carbon assessment. Internal POs to the given vendor incur an extra "tax" based on the cost to remove (or offset, in Google's case) the calculated amount of carbon.

Large vendors already offer the estimated carbon emissions of an order, and they certainly do when Microsoft or Google ask them to.

Aside: the moral high bar MS sets here is being "net zero", which is quite different than carbon neutral.

If you watch the two minute video or read the 5-page essay “I, Pencil”, you will see why.

The vendors’ vendors’ vendor is not in the loop. They will not know that the raw materials they are mining in a 3rd world nation are being consumed ultimately by google.
