As reported to EPA under the mandatory GHG Reporting Protocols (40 CFR Part 98, Subparts C and D). Purchased power emissions should be calculated using the most relevant and accurate of the following methods: For direct purchases, such as PPAs, use the direct emissions data as reported to EPA. For market purchases where emissions are unknown, use applicable regional or national emissions rate: ISO/RTO-level emission factors Climate Registry emission factors E-Grid emission factors Baseline 2005 Refer to the 'Definitions' tab for more information on each metric 2023 2024 2025 As reported to EPA under the mandatory GHG Reporting Protocols (40 CFR Part 98, Subpart DD).
