SUBJECT:	Proposed Updates to Chemical-Specific and Default GWPs for the Greenhouse Gas
      Reporting Rule

This memorandum reviews the mathematical basis for certain chemical-specific and default global warming potentials (GWPs) proposed in the Supplemental Proposal to the proposed Revisions and Confidentiality Determinations for Data Elements Under the Greenhouse Gas Reporting Rule that were published on June 21, 2022 (87 FR 36920, hereafter referred to as "2022 Data Quality Improvements Proposal"). As discussed in the Supplemental Proposal, the EPA is proposing revisions to Table A - 1, the Greenhouse Gas Reporting Program's compendium of GWPs, to update the chemical-specific GWP values of certain GHGs to reflect the GWPs from the IPCC Fifth Assessment Report (hereinafter referred to as "AR5") and, for certain GHGs that do not have chemical-specific GWPs listed in AR5, to adopt GWP values from the IPCC Sixth Assessment Report (hereinafter referred to as "AR6"). The EPA is also proposing to revise and expand the set of default GWPs in Table A - 1, which are applied to GHGs for which peer-reviewed chemical-specific GWPs are not available. Specifically, the EPA is proposing to revise the default GWPs in Table A - 1 by adding two new fluorinated GHG groups, modifying an existing group, and updating the existing default values to reflect the chemical-specific GWPs that the Agency is proposing to adopt from AR5 and AR6.
This memorandum reviews the data and analysis used (1) to conclude that weighting emissions using chemical-specific GWPs from AR6 is likely to lead to more accurate estimates of CO2-equivalent emissions than weighting emissions using default GWPs based on AR5, (2) to develop new fluorinated GHG groups and default GWPs for cyclic unsaturated halocarbons and for chlorofluorocarbons (CFCs), and (3) to calculate the proposed updated default GWP values for the updated fluorinated GHG groups.
Accuracy of Default GWP Values from AR5 vs. Chemical-Specific GWPs from AR6
As noted in the Supplemental Proposal, the EPA is proposing to adopt AR6 GWPs for 31 GHGs that have GWPs listed in AR6 but not AR5. All of these are fluorinated GHGs. Currently, default GWPs based on each GHG's fluorinated GHG group are applied to these GHGs. Each default value reflects the average of the known GWPs of the GHGs in a group of chemically similar fluorinated GHGs. While the default value is expected to be an unbiased estimate of the GWPs of other fluorinated GHGs in that group, it is not expected to be as accurate as a chemical-specific GWP for any given GHG, which reflects the radiative efficiency and atmospheric lifetime of that GHG. The chemical-specific GWPs in each group vary over a range. For example, as shown in Table 1 below, the chemical-specific AR5 GWPs in each group show relative standard deviations between 30 and 170 percent, depending on the group. Thus, using chemical-specific GWPs instead of default values would generally be expected to better reflect the atmospheric impacts of these gases.
One issue that arises with using a combination of AR6 and AR5 GWPs is that slightly different methods were used to calculate each set of GWPs, potentially resulting in inconsistencies among the chemical-specific GWPs in Table A-1. The AR6 GWPs reflect the climate-carbon feedbacks for the GHG whose GWP is being evaluated, while the AR5 GWPs that EPA is proposing to adopt (from Table 8.A.1) do not. GWPs that reflect the climate-carbon feedbacks for the GHG whose GWP is being evaluated are slightly larger than GWPs that do not. This difference could potentially result in overweighting the atmospheric impacts of GHGs whose GWPs are drawn from AR6 relative to GHGs whose GWPs are drawn from Table 8.A.1 of AR5. However, the analysis shown below indicates that using chemical-specific GWPs will lead to more accurate estimates, even if there are some inconsistencies among those GWPs. In AR5, reflecting climate-carbon feedbacks for the GHG whose GWP is being evaluated results in an increase in the evaluated GWP of 11 to 22 percent, with the higher fractional increase being associated with shorter-lived gases with lower GWPs. In contrast, as shown below, using default GWPs based on AR5 rather than chemical-specific GWPs from AR6 would result in overestimating GWPs by as much as 3,000 (equivalent to a relative error of 1,200 percent) and underestimating GWPs by as much as 4,900 (equivalent to a relative error of -35 percent), with over- and underestimates averaging 1,200 and 950 respectively (and relative errors averaging 770 percent and -60 percent, respectively).
Tables 1, 2, and S-2 below show the data and calculations used to arrive at these conclusions. (Table S-1 provides a key to fluorinated GHG group numbers used in Table S-2; all Tables numbered with an "S" appear in the Supplementary Material section at the end of this memorandum.) Table S-2 displays the chemical-specific GWPs in AR5 for the fluorinated GHGs whose GWPs are evaluated in AR5. Table 1 calculates the averages, rounded averages, and standard deviations of the GWPs of the compounds in each fluorinated GHG group in Table S-2. The rounded averages are used in Table 2 as hypothetical default GWPs that would be adopted if the chemical-specific AR6 GWPs were not adopted. (Note that the hypothetical default GWPs, which are based exclusively on AR5 GWPs, are often different from both the proposed default GWPs, which are based on a combination of AR5 and AR6 GWPs, and from the default GWPs currently in Table A-1, which are based on a combination of AR4 and AR5 GWPs. However, the default GWP assigned to groups 9, 10, and 11 in Table 1, "1," is the same for all three sets. The statistics underlying the proposed default GWPs can be found in Table 4 in the next section.)
For each fluorinated GHG that has a chemical-specific GWP in AR6 but not in AR5, Table 2 compares the chemical-specific AR6 GWP value to the hypothetical default GWP calculated in Table 1. Table 2 shows the difference between the chemical-specific and default GWP in both absolute and relative terms. A negative number indicates that the default GWP underestimates the chemical-specific GWP while a positive number indicates that the default GWP overestimates the chemical-specific GWP. As noted above, the absolute errors range from +3,000 to -4,900 (equivalent to relative errors of 1,200 and -35 percent respectively). The relative errors range from +2400% to -99%, excluding relative errors where both GWPs are less than or equal to one. Table 3 shows the maximum overestimates and underestimates in both absolute and relative terms. It also shows the average absolute and relative overestimate and average absolute and relative underestimate. (To avoid skewing the results with inconsequential differences, instances where the default GWP would differ from the chemical-specific GWP by less than one were excluded from the analysis. In all these cases, the default GWP was one.)

Notes to Table 2:
* Unsaturated cyclic fluorocarbons are grouped with unsaturated non-cyclic fluorocarbons since AR5 has just one unsaturated cyclic fluorocarbon, whose AR5 GWP is very similar to that of the unsaturated non-cyclic fluorocarbons.
** EPA proposed to include unsaturated CFCs in Group 9 (along with unsaturated PFCs and HFCs) in the 2022 Data Quality Improvements Proposal

Updated Default GWPs and New Fluorinated GHG Groups for CFCs and Cyclic Halogenated Compounds
As noted in the Supplemental Proposal, the default GWPs in Table A-1 are calculated based on the average of the chemical-specific GWPs of the compounds in each fluorinated GHG group. Each fluorinated GHG group is composed of compounds with similar chemical structures, which have similar atmospheric lifetimes and GWPs. Table 4 displays the proposed updated fluorinated GHG groups, the average and standard deviation of the GWPs of the compounds in each group, and the proposed default GWP for each group. (Note that the statistics and default for the "Remaining Fluorinated GHGs" group reflect the GWPs of all fluorinated GHGs with chemical-specific GWPs in AR5 or AR6, except for fluorinated GHGs that do not contain carbon, i.e., except for SF6 and NF3). These updates are based on the proposed chemical-specific GWPs from AR5 and AR6, which are displayed in Table S-3 in the Supplementary Material.
As discussed in the Supplemental Proposal, Table A-1 has not previously included a fluorinated GHG group for saturated CFCs because the GHGRP does not require reporting of most CFCs, which are defined as "controlled substances" under the EPA's ozone protection regulations at 40 CFR part 82 and are therefore excluded from GHGRP coverage. However, AR6 includes GWPs for two saturated CFCs that are not defined as "controlled substances" under part 82 and that are therefore covered by the GHGRP. As noted in the Supplemental Proposal and shown in Table 4, the average GWP of the two saturated CFCs (4,900) is markedly different from the closest default (rounded average) GWPs proposed for other groups (3,000 for saturated HFCs with two or fewer carbon-hydrogen bonds and 6,600 for saturated HFEs and HCFEs with one carbon-hydrogen bond). Given the numerical differences between the average GWP for the saturated CFC group and the GWPs for the other groups, as well as the chemical differences between CFCs, HFCs, and HFEs, the EPA is proposing a separate group and separate default GWP for saturated CFCs.
AR6 also includes four new GWPs and one revised GWP for unsaturated cyclic HFCs and PFCs. The AR6 GWPs for the unsaturated HFCs and PFCs range from 25.6 to 126. As shown in Table S-3, these GWPs are markedly larger than the GWPs for the non-cyclic unsaturated halogenated compounds currently in the ninth fluorinated GHG group, most of which are less than 1. Figure 1 illustrates this difference in GWPs, which appears to be attributable both to longer atmospheric lifetimes and to greater radiative efficiencies for cyclic unsaturated compounds, as shown by Figures 2 and 3. The default GWP proposed for the new group is 58, far higher than the value of 1 currently in effect for the unsaturated halogenated compounds in the ninth fluorinated GHG group. As noted in the proposed rule, EPA is proposing a new group for unsaturated cyclic fluorocarbons for these reasons. (WMO Scientific Assessment of Ozone Depletion: 2018 also includes a separate category for cyclic unsaturated HFCs and PFCs, which the authors refer to as "cycloolefins," in their table of GWPs. See page 2.10 of the report.)
