Read the method labels
A location-based result uses the relevant electricity-system basis defined by the method. A market-based result uses the applicable contractual-data hierarchy and quality requirements. Method labels should remain beside a reported amount.
Keep method-specific checks visible
| Layer | Check |
|---|---|
| Location basis | Relevant geography, period and factor coverage |
| Market basis | Eligible data and contractual quality requirements |
| Activity | Consistent purchased-energy amount and boundary |
| Reporting | Applicable published method, not an inferred legal rule |
Avoid an automatic zero-emissions conclusion
A purchase contract or certificate label alone does not prove that every method condition is satisfied. It also does not measure all life-cycle emissions or the global physical impact of an action. Keep those questions distinct.
Separate published guidance from revisions
The published 2015 guidance and subsequent correction record are distinct from consultation proposals. The July 2026 development announcement describes future work, not an already issued consolidated replacement.
