a major healthcare company has reduced its data center carbon footprint by more than 80%. what action has likely contributed to this the most?

A major healthcare company most likely reduced its data center carbon footprint by more than 80% primarily by shifting from on-site data centers to the public cloud. Public cloud providers typically operate much more efficient and sustainable data centers, consuming significantly less power—studies show around 84% less power consumption compared to on-premises infrastructure. This shift results in substantial carbon footprint reduction compared to other actions such as employee commuting incentives or adding electric vehicles to the fleet, which do not directly impact data center energy use.
