Formula
C = E_covered / E_total × 100Divide energy covered by qualifying contractual information by total energy in the applicable market-based boundary and multiply by 100.

Evidence and status sources
Sustopedia checked each record-specific claim directly against primary publisher material. Labels distinguish current measurement authority from future compatibility and corroborative, legal, edition, or method status context. Corroborative evidence can support a stated limitation but cannot establish the core measurement by itself.

Method disclosures required
Source-edition basis: GHG Protocol Scope 2 Guidance, 2015 publication.
- Indicate the proportion of total electricity consumption under the market-based method that is supported by actual market data with contractual information.
- Define the operations included in the coverage assessment.
- Disclose that coverage is measured by energy usage.
- Disclose the proportion covered by the market-based method and the proportion for which the location-based method is used as a proxy.
- Describe the basis used to classify operations as covered by the market-based method or by the location-based proxy.
Record-specific limitations
- The percentage is limited to electricity consumption reported using the market-based method.
- The guidance specifies actual market data with contractual information but does not provide a separate eligibility calculation in the cited passage.
- This is a contextual coverage disclosure and does not measure market-based Scope 2 emissions.
- The guidance frames this disclosure for companies initiating market-based reporting.
- Coverage is measured using energy usage; it is not a percentage of sites, facilities, revenue, employees, or emissions unless separately disclosed.
Interpret this metric with the stated reporting boundary, period convention, value shape, and unit. Results prepared with different boundaries or conventions may not be directly comparable.
Measurement evidence supports the core record-specific claims described above. Corroborative evidence can support limitations, while compatibility and status sources provide their separately labelled context. None of these cards by itself determines an organisation's legal applicability, filing readiness, assurance status, or compliance conclusion.
