And both of these companies build and purchased more renewable energy sources than all 100+ countries combined. Microsoft has committed to be carbon free by 2030, and while I don’t belive in their commitment, they at least seem to be trying contrary to most nations. They even invested in nuclear plants for their power needs.
You can fault both companies for a lot of different reasons, but in terms of carbon emissions due to power usage, they are better than 99.9% of the countries on that list.
