US Climate Leaders factor set
IBM® ESG Suite has factors loading from this factor set since 2013. There is no fixed publish date for the factor set. In the past it has followed a rough time interval of every two years, usually published in the first quarter of a year. Since 2020 the schedule has been adjusted to once a year.
Envizi ESG Suite in general loads the latest factors into the Envizi ESG Suite platform as soon as it is published by the US EPA. This factor set is a free resource that is openly available on the US EPA website.

| Upcoming publication date | Publishes annually in first or second quarter of a year. Upcoming publication date: April 2025 |
| Geographical coverage | By default factors are applied to all regions, providing this factor set is chosen as one of your nominated factor sets. |
| Data type coverage | Stationary Combustion Mobile Combustion CO2 Mobile Combustion CH4 and N2O for On-Road Gasoline Vehicles Mobile Combustion CH4 and N2O for On-Road Diesel and Alternative Fuel Vehicles Mobile Combustion CH4 and N2O for Non-Road Vehicles Steam and Heat Scope 3 Category 4: Upstream Transportation and Distribution and Category 9: Downstream Transportation and Distribution Scope 3 Category 5: Waste Generated in Operations and Category 12: End-of-Life Treatment of Sold Products Scope 3 Category 6: Business Travel and Category 7: Employee Commuting Global Warming Potential (GWP) Global Warming Potential (GWP) for Blended Refrigerants Electricity is also published in this publication, but this is loaded through the US eGRID electricity factors as a separate process. |
| Effective and published dates | Effective dates and published dates always starts with the first month of a calendar year and
end with the last month of a calendar year. For example, Effective from = Jan-2016
and Effective to = Dec-2017. For more information on effective and published dates,
see Assigning factors.If you require a custom period for your factors this will need to be managed as Custom factors. |
| Global Warming Potential (GWP) | Factors with an effective date later than 2012 use GWP defined by 2007 IPCC AR4 (N2O GWP =
298, CH4 GWP = 25) for equivalent CO2 amount calculations. Factors with an effective date starting in 2024 use GWP defined by IPCC AR5 (N20 GWP = 265, CH4 GWP = 28) for equivalent CO2 amount calculations. |
| Indirect CO2e | Indirect factors are published for some fuel sources currently, and use the values provided by DEFRA. This is planned to be expanded in the future. |
