"Rollups" are aggregated GHG emissions. Rollups are automatically calculated by Cal e-GGRT according to requirements of Subpart A--General Provisions and cannot be overridden by reporters.
For source categories, 40 CFR 98.3(c)(4) requires the following rollup calculations:
- Annual emissions (excluding biogenic CO2) aggregated for all GHGs from all applicable source categories, expressed in metric tons of CO2e calculated using Equation A--1.
- Annual emissions of biogenic CO2 aggregated for all applicable source categories, expressed in metric tons.
- Annual emissions from each applicable source category, expressed in metric tons of each applicable GHG listed below:
- Biogenic CO2
- CO2 (excluding biogenic CO2)
- CH4
- N2O
- Each fluorinated GHG (including those not listed in Table A--1)

For supplier categories, 40 CFR 98.3(c)(5) requires the following rollup calculations:
- Total quantity of emissions aggregated for all GHG (excluding biogenic CO2 and fluorinated GHGs that are not found in Table A-1) from all applicable supply categories in Table A--5, expressed in metric tons of CO2e and calculated using Equation A--1.
- Quantity of CO2, CH4, N2O, and each fluorinated GHG (as defined in ยง98.6), including those not listed in Table A--1 from each applicable supply category in Table A--5, expressed in metric tons of each GHG. For fluorinated GHG, report emissions of all fluorinated GHG, including those not listed in Table A--1 of this subpart. For fluorinated GHGs, calculate and report CO2e for only those fluorinated GHGs listed in Table A--1.
