Navigating Scope 2 emissions often feels like choosing between the "physical reality" of your local power grid and the "contractual reality" of your green energy purchases. To keep your reporting credible and compliant, the GHG Protocol requires Dual Reporting, meaning you must disclose both location-based and market-based figures side-by-side.

While location-based data grounds your footprint in the actual carbon intensity of your regional wires, the market-based method highlights the impact of your specific investments in renewable energy. By reporting both, you avoid the trap of accidental greenwashing and provide stakeholders with a transparent view of both your operational efficiency and your procurement power.

Mastering this two-pronged approach is the single most important step in turning complex utility bills into a clear, defensible climate strategy.
