Carbon Emissions Analysis power-based calculation support

Using the Carbon Emissions Analysis page in Emissions Management, paying commercial Oracle Cloud Infrastructure customers can track their estimated carbon emissions footprint while using OCI services. Carbon Emissions Analysis is an easy-to-use visualization tool that allows you to generate charts, data tables, and CSVs of carbon emissions usage based on customizable parameters such as carbon emissions factors, calculation methods, time ranges, filters, and grouping dimensions.

OCI leverages Green House Gas (GHG) protocol guidance to automate carbon emissions calculations for customers' purchased services using new power-based calculations, which track the amount of power consumed (in kWh) by service workloads, aligning with GHG protocol guidelines and EU/UK regulations. This method allocates energy consumption from OCI data center hardware (both dedicated and shared) to your resource workloads, then multiplies it by a regional carbon emissions factor based on the power grid mix of renewable and non-renewable energy.

Spend-based calculations calculate emissions by multiplying a customer’s service spend (pre-discount) by a regional carbon emissions factor, based on the ORACLE Clean Cloud OCI Data Sheet.

Power-based calculations are more exact but are only supported by some OCI services. For other services, use spend-based calculations.

For power-based calculations, two types of carbon emissions factors are available:

• Location-based emissions: Reflects the region’s power grid emissions, which may vary from partially renewable to 100% renewable.

• Market-based emissions: Includes Oracle's renewable energy certificates and grid purchases to offset emissions, resulting in zero carbon emission factors in regions such as Europe.

Spend-based calculations support only the market-based emissions factor.
