Emission Factors

Our comprehensive database of emission factors is perhaps the largest and most accurate in the world.

What Are Emission Factors?

Emission factors are conversion factors applied to activity data to enable the conversion from raw data to estimated GHG emissions. In calculating GHG emissions from a particular source, geographically relevant and up-to-date factors should be sourced, and care must be taken when selecting the factor.

Geographically specific.

Up-to-date.

Geographically specific, up-to-date emission factors are key to accurate, auditable and transparent Greenhouse Gas Assessments.

Published by numerous organizations and updated often, the task of compiling and ensuring the accuracy of a comprehensive dataset is costly and time-consuming.

The data team behind Ecometrica’s award winning sustainability platform tracks hundreds of sources on a regular basis.

Emission Factor Database

EmissionFactors.com enables companies to download spreadsheets of the most common global emission factors to use in their own spreadsheets. You can also search our comprehensive emission factor database by year, location, emission source and category.

Key Phrases

Greenhouse Gas (GHG)2023-01-16T20:45:23+00:00

A greenhouse gas (GHG or GhG) is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect.  The greenhouse gases (GHG) included in the atmospheric emissions are those covered by the Kyoto Protocol: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur hexafluoride (SF6), and nitrogen trifluoride (NF3). These gases contribute directly to global warming and climate change, because of their positive radiative forcing effect. The potential of each GHG to cause global warming is assessed in relation to a given weight of CO2, so all greenhouse gas emissions are measured as carbon dioxide equivalents (CO2e).
