The Cool Farm Alliance (CFA) utilizes reference data for grid electricity emission factors in collaboration with the International Energy Agency (IEA). Here are the key details regarding the use of these factors:
1. IEA License: The CFA has secured a license agreement with the IEA (International Energy Agency) to access electricity grid emission factors up to the year 2019.
2. Annual Updates: An annual update of regional electricity factors is made available through this collaboration. This ensures that the emission factors remain up-to-date and reflect the evolving nature of electricity generation.
3. Use of Latest Available Factors: For years following 2019, the Cool Farm Tool (CFT) employs the most recent available emission factors. For example, in 2018 calculations, the emission factors for 2018 are used, and in 2022 calculations, the factors from 2019 serve as the basis.
4. Sub-National Factors: Sub-national level factors, such as those for specific U.S. states, are not available. Instead, emissions are calculated at the national level, taking into account the aggregated electricity generation data for the entire country.
5. Inclusion of Key Factors: The CFT incorporates trade adjustments and distribution losses in the calculation of electricity grid emissions. However, it's important to note that well-to-tank emissions are not yet included, as the IEA is actively working on developing this aspect of emissions data.
In summary, the CFT relies on a collaborative effort with the IEA to access and use electricity grid emission factors up to 2019, with annual updates to ensure accuracy. While sub-national data is not available, national-level calculations are employed, including trade adjustments and distribution losses, with the anticipation of further enhancements as emissions data evolves.
