Carbon Footprint

Klarity supports the cloud carbon footprint calculation and saving suggestions for selected AWS resources.

The formula of carbon footprint calculations (CO2e)

CO2e = kilowattHours * emissionsFactors[region]

kilowattHours is calculated based on different types, like Compute, Memory, Networking and Storage types (Ref.1).

emissionsFactors is a constant which is defined in the CCF (Cloud Carbon Footprint) code for different providers and regions (Ref.2).

Notes: Most of the values are constant, but they are different for each type, resource, and cloud provider
