CO2 / GHG Emission Factor Databases

We know that carbon accounting can be time-consuming, especially when done manually. While Avarni streamlines this process, we also wanted to make it easier for those still working with spreadsheets. This page provides a comprehensive list of global CO2 / GHG emission factor databases, helping you find the data you need in one place.

How to use this list of emission factor databases

Use the filters to find the emission factors you need for your carbon calculations and reporting. For example, to view all electricity emission factors by country, simply search for "electricity" under the emission factor Type.

FAQs

What is an emission factor?
An emission factor is a coefficient that quantifies the amount of greenhouse gas released per unit of activity (e.g., kg CO2 per liter of fuel burned).
How are emission factors determined?
Emission factors are developed through scientific studies, measurement campaigns, and industry best practices.
Why are emission factors essential for carbon accounting?
They provide a standardized way to estimate emissions across different sectors and activities, ensuring consistency in reporting.
How do you know which emission factor to use?
Choosing the right emission factor depends on factors such as activity type, geographical relevance, and the reporting standard being followed. To learn more, check out these resources:
‍‍
How often are emission factor databases updated?
Update frequency varies by database. Some, like the IPCC and EPA databases, are updated annually or in response to new scientific findings.
Can I use multiple databases for a single report?
Yes, in some cases, organizations use multiple sources to ensure the most accurate data for different activities or locations.
