10.12.2025: Heating Conversion Factor Update

Clare avatar
Written by Clare
Updated this week

On December 9th 2025, we updated the conversion factors used to calculate emissions emerging from heating homes and facilities. This reflects the notable changes in average temperatures across many countries, which directly influence heating demand and related emissions. This update will apply to 2026 emissions using the following calculation methods:

This change ensures your heating-related emissions calculations are aligned with the most recent climate data available. As a result, you may notice variations in your 2026 emissions figures compared to 2025.

For transparency, we’ve outlined the percentage difference between the 2025 and 2026 heating conversion factors by country and month. Click the expanders below to learn more.
