To calculate emissions on the Measure dashboard, Workiva Carbon uses emission factor sets from the publications listed in this article.
Emission factor library versions
New and updated factor sets become available to you with every new version of Workiva Carbon’s emission factor library. When a new library version is published, it will be set as the default for any reporting year with no data uploaded. Make sure to select the library version that is right for your company before importing data for a new reporting year. To learn how to select the right library version for your company and how recalculations work, view Factor updates and recalculations.
For customers outside of the Asia-Pacific region, Version 1 of the emission factor library includes all emission factors that are live in Workiva Carbon as of August 2025. Customers who are uninterested in changes to emission factors currently applied to their entries should remain on Version 1.
Publications included:
For customers within the Asia-Pacific region, Version 2 includes all emission factors live in the platform as of August 2025. Asia-Pacific customers who are uninterested in changes to the emission factors applied to their inventory should remain on Version 2.
Changes:
The difference between Version 1 and Version 2 of the emission
factor
library is isolated to the spelling of Australian grids. In Version
1,
Workiva Carbon retained the territory and grid names for Australian
electricity
grids as published in each year's publication; this inconsistent
naming
convention inadvertently impacted emission factor selections.
Version
2 includes changes to the naming of Australian grids across
Australian National Greenhouse Accounts (NGA) factors
to ensure consistent selection of grid-specific values.
Beyond this change to Australian grid naming, Version 1 and Version
2
are identical.
Version 3 includes all emission factors from Version 2 and the addition of publications released since June 2024.

In Version 3.1, the release year of an emission factor is matched to an entry’s reporting year. This means the most recently released emission factor will be applied to an entry rather than an emission factor calculated off of the same year’s data. Version 3.1 includes all of the same emission factors as Version 3.
In previous versions, Carbon stored the release year and data year of an emission factor separately, and emission factor selection has aimed to match an entry’s reporting year to an emission factor’s data year. To learn more about data year and release year, view the Methodology section of Factor updates and recalculations.

Changes
Correction of CH4 GWP value
Prior versions of the EF Library applied an incorrect GWP value when converting methane emission factors to CO2e. This error impacts emission results in stationary combustion and vehicles. Adoption of V4 and recalculation with corrected values are encouraged.

| Vehicles> Mobile combustion by vehicle> CNG, Diesel, Gasoline/petrol, LNG, and LPG vehicles | All |
Correction of carpooling emission factor calculation method
The emission factor applied to carpooling entries assumes that a passenger car has more than one occupant during daily commuting. Since an emission factor for a passenger car assumes one passenger per vehicle, Workiva Carbon calculates an emission factor for carpooling entries by dividing a passenger car emission factor by the average passenger count within a carpooling vehicle: 1.06 passengers in North America and 1.5 passengers in Europe. Prior versions of the EF Library inconsistently calculated a carpooling emission factor from the EPA’s passenger car emission factor. This inconsistency caused results of carpooling entries to be incomparable year over year. Adoption of V4 and recalculation with corrected values are encouraged.
| Entry location | Geographic location |
|---|---|
| People> Employee commuting> Carpool | All |
*Impacting reporting years 2024 and later
Removal of internally calculated road and non-road emission factor values in the Vehicles calculator
There is an option to enter your mobile combustion activity data by vehicle or by fuel within Workiva Carbon’s Vehicles calculator. Entries within the Mobile combustion by fuel section do not have an associated vehicle class, so prior library versions included CH4 and N2O values that were averages of multiple vehicle classes that shared fuel type. These calculated averages have been removed and replaced with publicly available values. Learn more about changes to Vehicles calculations here.
| Entry location | Geographic location |
|---|---|
|
Vehicles> Mobile combustion by vehicle Vehicle class: Road vehicle, Non-road vehicle |
All |
|
Vehicles> Mobile combustion by fuel Road and non road and equipment |
All |
Removal of internally calculated passenger car values in Business travel and Employee commuting
Prior library versions included country-specific emission factors which applied an EPA-derived CO2:CH4:N2O ratio to the IEA’s published CO2 value to estimate a complete GHG breakdown. These calculated values have been removed and replaced with published values applied as regional proxies.
| Entry location | Geographic location |
|---|---|
| People> Employee commuting> Car | All |
| People> Business travel> Road travel> Tracking by distance> Car, Truck/Van | All |
Removal of regional averages representations
Workiva Carbon’s EF selection logic applies a regionally assigned emission factor in the absence of a country-specific emission factor for a given activity. Previously, Workiva Carbon’s regional EF assignments included an average of published emission factors from within the same region. These regional average values have been removed and replaced with published values applied as regional proxies.

| People> Business travel> Rail travel | All regions excluding North America |
| People> Commuting> Commuter rail, Subway/rapid transit, Bus or shuttle | Europe excluding United Kingdom, Ireland, France |
Removal of GHG breakdown from different publications
Though a given activity may emit multiple greenhouse gases, some emission factor publishers may not include a value for each gas in their dataset. Prior versions of the EF Library completed the GHG breakdown of a calculation with values from different publications. This behavior has been changed to ensure that all greenhouse gases in a calculation use emission factors from the same publisher.

NAICS-6 commodity level spend-based factors available for selection
Prior emission factor library versions include spend-based emission factors from v1.1.1, v1.2.3, v1.3, and v1.4 at the level of BEA Summary Industry. V4.1 includes spend-based emission factors from v1.2, v1.3, and v1.4 at both the BEA Summary Industry level and the NAICS-6 commodity level to enable customers to map their activity at their chosen level of granularity.
Note: To learn about new calculation changes in Purchases, view Measure purchases. To learn about how Workiva Carbon generates USEEIO emission factors at the BEA Summary Industry-level, view Workiva Carbon's BEA summary EFs for USEEIO supply chain factors.
Replacement of fugitive emissions GWP values
In Version 4.1, GWP values published by the UK DBEIS for fugitive emissions (fire suppressants and refrigerants) have replaced values from the US EPA, The Climate Registry, 3M, and Honeywell. GWP values for blended gases in prior library versions had excluded the Non-Kyoto component of the gas and left Non-Kyoto emissions unaccounted for. Replacing these individual values with the separate Kyoto and Non-Kyoto values published by the UK DBEIS will enable complete results that account for a blend’s in and out of scope components. Selection of V4.1 and recalculation are encouraged for customers with data entered in the Fire suppressants or Refrigerants sections of the Buildings calculator.
Removal of US EPA air travel emission factors
Air travel emission factors available in the US EPA’s Emission Factors for Greenhouse Gas Inventories are a subset of values originally published by the UK DBEIS. The UK DBEIS publishes air travel factors broken down by flight distance, flight class, and with or without radiative forcing. The EPA republishes the average flight class factor of each flight distance without radiative forcing. To support flight class granularity and consistently apply emission factors which include radiative forcing in air travel calculations, Workiva Carbon has removed the EPA’s republished values in favor of using the UK DBEIS values across all locations. To ensure consistent application of UK DBEIS air travel factors, selection of V4.1 and recalculation are encouraged for customers with data entered in the Air travel section of the People calculator. To continue using EPA emission factors for air travel, customers may configure these emission factors within the Custom Measure category.
