The GHG Protocol Scope 2 Guidance asks companies to report purchased electricity emissions using two methods side by side.
Location-based
Uses the average emission factor of the grid where the electricity is consumed. It reflects the physical reality of the grid you are connected to.
Market-based
Uses the emission factors from the contractual instruments you hold, such as energy attribute certificates, power purchase agreements or supplier-specific factors. Electricity not covered by an instrument uses a residual-mix factor.
