Contracts such as PPA (Power Purchase Agreements). |
If you purchase renewable energy credits (RECs) or have Power Purchase Agreements (PPAs) where you know the specific emissions associated with your purchased electricity, you can use the Market-Based method to enter the related amount of emissions in the worksheet. This will feed into your dashboards and reports by default, making it easy for you to show the impact of your green energy decisions!
