Salesforce faulty carbon calculator
According to the Salesforce carbon savings calculator (www.salesforce.com/company/sustainability/savings.jsp) if I'm based in Europe and I move my existing IT platform (with 10,000+ users) to the Salesforce cloud, I will reduce my carbon emissions by 87%.
This is, of course, complete baloney. Salesforce's data centers are in the US (45% of generation there is from coal) and Singapore where all but 3% of energy comes from fossil fuels.
On the other hand, if my on premise IT platform in Europe is based in France, it is powered roughly 80% by nuclear power which has a very low carbon footprint. If it is based in Spain, Spain generates 40% of its power from renewables, and so on.
