Scope 2 reporting sounds straightforward until disclosure season begins. Most organizations know they must account for purchased electricity, but uncertainty remains around which emission factor to use, how procurement instruments affect the result, and what level of documentation is required for defensible claims. The distinction between market-based and location-based reporting is where those questions converge.
What the two methods are designed to show
Location-based reporting answers a simple question: what emissions intensity is associated with the grid where the electricity was consumed? It gives a view of the average system conditions around the facility.
Market-based reporting answers a different question: what emissions profile should be associated with the electricity purchase decisions the company made? It captures the effect of contractual instruments, where the market and methodology allow them.
Why both numbers matter
Reporting both values prevents oversimplification. A company may have low market-based emissions because it bought renewable attributes, while the local grid serving a facility remains carbon intensive. Conversely, a site on a relatively clean grid may still have limited procurement options.
Using both figures gives stakeholders a more complete picture of operational exposure, procurement quality, and where further decarbonization work is still needed.
Where reporting programs break down
Problems usually come from incomplete evidence chains. Teams may have invoices and certificates, but lack a rigorous mapping between those instruments and in-scope load. Or they may have consumption totals, but no clear audit trail showing which factors were applied and why.
This becomes especially painful in multi-country portfolios where utility data quality, contractual structures, and disclosure expectations vary by market.
- Unclear organizational and operational boundaries
- Mismatched reporting periods between certificates and consumption
- Manual emission factor selection without governance
- Weak documentation for assurance review
What a stronger Scope 2 process looks like
A robust process starts by standardizing data collection at the facility level. Meter data, bills, contracts, certificates, and calculation logic should all flow into one controlled reporting workflow.
That enables repeatable calculations, easier evidence retrieval, and a more transparent conversation with auditors, sustainability teams, and procurement stakeholders. In other words, better reporting is usually a data operations problem before it is a disclosure problem.
