Our Enhanced Methodology
1. Full Transparency
We maintain complete transparency in our emission factor usage:
All emission factors used in calculations are available in carbon auditable exports
Exception: IEA (International Energy Agency) electricity factors cannot be shared in output reports due to licensing restrictions
For questions about IEA factors, contact our support team at support@keyesg.com
2. Entry Method Flexibility
You have control over your emission factors:
Use platform default emission factors for standard calculations
Override with your own emission factors using supplier-specific or direct entry methods
Choose the approach that best fits your reporting needs
3. Annual Updates and Change Log
We provide predictable, transparent updates:
Emission factors are updated and locked annually in January
All admin users receive a detailed change log each January
No surprise updates during peak reporting seasons
4. Most Recent Data Sources
Our emission factors are based on the latest verified data:
Sources include leading providers (IEA, DEFRA, EPA, and others)
Data is current as of December of the preceding calendar year
Only verified, authoritative sources are used
5. Year-Long Consistency
Stable factors throughout the reporting year:
Once locked in January, emission factors remain unchanged for the entire calendar year
Eliminates mid-year calculation changes that could affect your reporting
Provides predictability for annual reporting cycles
Impact on Your Reporting
Implementation Timeline
Through 2025: All current emission factors remain unchanged
January 2026: Latest available emission factors will be locked in for the year
Ongoing: Each January, you'll receive an email with emission factor change logs
What This Affects
All built-in emission factors across Scopes 1, 2, and 3
Metric calculations that incorporate these emission factors
Historical data: Previous emissions calculations remain unchanged and use the factors that were in place at the time of original reporting.

Important Note on Historical Data
When re-submitting historical submissions that include electricity data, you may see different calculated values even when your input values remain the same. This is due to our updated emission factor methodology. Future edits will consistently use this new calculation approach.
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.
