Default emission factors sometimes change over time as the components of energy (electricity, fuel, etc.) change and as emission factor quantification methods are refined. The Registry updates emission factors on an annual basis in January to reflect the most up-to-date knowledge. The 2014 emission factors are part of the CRIS calculation tool and must be used to calculate 2013 emissions. Members who choose to report emissions data from previous years can use the most up to date emission factors in the CRIS calculation tool at the time they report.
- NEW: 2014 Climate Registry Default Emission Factors – Released April 11, 2014
- Table 14.4 in this document was updated to add 2011 defaults. In all other ways it is identical to the version released on January 10, 2014.
- On November 29, 2013, U.S. EPA updated several default emission factors for the Greenhouse Gas Reporting Program. These updated factors are not incorporated in The Climate Registry’s 2014 Default Factors or CRIS. However, Members can use the updated EPA emission factors to report 2013 data to The Climate Registry as long as they use factors from the same year consistently throughout their annual report. To support this, the document below includes the updated factors and identifies which defaults have been changed (in red). Please contact the help desk with any questions about how to include these updated factors in an inventory.
- Archived versions of the emission factors
The Climate Registry relies on U.S EPA’s emission factors from the eGRID to calculate electricity emissions in the U.S. Because the release of the eGRID factors by EPA varies from year to year, The Registry updates CRIS at the end of each year with the most current emission factors. With these regular updates, CRIS is ready each January for reporting the new emissions year. At any time that EPA publishes updated eGRID factors, The Registry shares these with our Members. If they are available before the reporting deadline, Members have the option of customizing their emission factors in CRIS to use any updated eGRID factors – as long as they use factors from the same year consistently throughout their annual report.
- NEW: On February 26, 2014 U.S. EPA updated the eGRID emission factors to reflect data from 2010. These emission factors can be accessed here: 2010 eGRID subregion Output Emission Rates. Members who choose to report using the updated defaults consistently across scope 2 should use the annual total output emission rates in the document linked above.
Registry Members Reporting to the Electric Power Sector (EPS) Protocol have the option to develop utility-specific retail electric or special power electric delivery metrics that their customers can use when quantifying scope 2 emissions. Registry Members who are customers of these utilities can use the relevant emission factors below when reporting scope 2 emissions to The Climate Registry:

- solar electric, including concentrated solar thermal
- certified low-impact or EcoLogo hydropower
- pipeline or irrigation canal turbine hydropower
- biomass (non-chemically treated woody waste, agriculture crops or waste)
- Eligible biomass cannot include wood that has been coated with paints, plastics, or formica; wood that has been treated for preservation with materials containing halogens, chlorine or halide compounds like chromated copper arsenate-treated materials, or arsenic, and railroad ties.
Please note, The Registry’s criteria are aligned with the most recent version of the Green-e Energy National Standard program.
- Metric 1: Emissions per passenger mile travelled
- Metric 2: Emissions per vehicle mile
- Metric 3: Emissions per revenue vehicle hour
The American Public Transportation Association (APTA) and Canadian Urban Transit Association (CUTA) were integral to the development of these metrics and their expertise ensured that the metrics reflect the best knowledge of the transit industry.
In rare instances, Members find it necessary to develop a unique methodology to complete their greenhouse gas inventory. The Climate Registry has developed a process to approve these member developed methodologies. Complete information and the necessary forms for this process can be found below. We encourage Members to complete this process prior to entering the verification stage.
Please note that Members can only propose methodologies under three circumstances: 1) the methodology is for an emissions source not covered under The Registry’s guidance, 2) a member is unable to use any of the Registry-provided methodologies for a certain source or 3) a member is able to develop a methodology that is more accurate than The Registry’s methodology for that source. To be approved, the methodology must be at least as accurate as one of The Registry’s methodologies
Members that have confidential business information can be exempted from The Registry’s requirement to release facility-level information to the public. To obtain this exemption, Members must contact the help desk at firstname.lastname@example.org or (866) 523-0764 ext. 3.
The GRP was developed through a public stakeholder process. The Registry received over 1,140 individual comments on the draft GRP from 107 respondents representing industry, environmental non-governmental organizations, regulatory agencies, individuals and consultants.
