Scope 2 emissions cover the greenhouse gases produced when generating the electricity your organisation uses. For most businesses, electricity consumption is the single largest controllable source of emissions, and the emissions associated with it depend entirely on how that electricity was generated.
Two Ways to Account for Scope 2
The GHG Protocol recognises two methods.
Location-based accounting calculates your emissions using the average carbon intensity of the electricity grid in your region — reflecting the actual mix of generation sources on the grid you're connected to.
Market-based accounting calculates your emissions based on the specific electricity you have chosen to purchase. If you've contracted for renewable electricity or hold Energy Attribute Certificates (EACs), you can claim a lower — or even zero — Scope 2 emissions figure under this method.
Green Project uses the market-based method, which means your renewable energy purchases directly reduce your reported Scope 2 footprint.
The Renewable Energy section of your supplier profile is where you demonstrate which proportion of your electricity comes from renewable sources. Your customer may have set a specific renewable energy target for their suppliers. Completing this section accurately gives you credit for the renewable energy you already use and shows a clear path toward meeting your customer's requirements.
