What electricity emission factors do we use?
Since 2023, our default electricity emission factor (EF) source has been IEA (International Energy Agency) electricity rates. Starting in 2026. we use local grid rates by default. We believe these better reflect the actual carbon intensity of electricity usage in a company’s operating region, resulting in more geographically accurate Scope 2 emissions reporting.
How we update electricity emission factors
For current and future reporting years, we lock in the electricity EF rate in January each year:
This helps avoid mid-year EF changes during peak reporting season
The locked-in rate will be the most recent one available as of December from the prior calendar year.
This change is designed to improve consistency and reduce unexpected variances in reported emissions.
Choose Between IEA and Local Grid Rates
Companies can now choose whether to use:
IEA electricity emission factors, or
Local electricity grid rates, depending on what better fits their reporting needs.
This flexibility supports greater alignment with internal policies or external requirements.
Please note:
You can only switch EF types (IEA or local) for the current reporting year by contacting KEY ESG support.
EF selections for previous years are locked and cannot be changed retroactively.
Local rates cover all countries except for the following:

For countries that are not covered, we default to IEA’s Global set of emission factors, which is updated yearly
As a reminder, you can switch to IEA or use your own rates via the supplier-specific entry method
What Does This Impact?
These changes specifically affect:
Scope 2 electricity data points
Any metrics that incorporate electricity as an input, including but not limited to:
Source of energy consumed (auto)
Energy intensity metrics
Total energy consumption
Scope 3.3: Fuel and energy related activities
Scope 3.7: Home working
Where can I see my current and historical emission factors?
These can both be seen within your company settings in the KEY ESG Platform.
If you have any questions or would like to update your electricity emission factor selection, our support team is here to help at support@keyesg.com. We’re excited about these improvements and believe they will provide you with even more confidence in the accuracy and consistency of your ESG data.
