Cal e-GGRT Help

Q322. To what precision should emission values for CO2, N2O, and CH4 be reported in e-GGRT?

Note: The Cal e-GGRT help system includes general instruction on using the California GHG reporting tool. However, the help system may not explain differences between California and U.S. EPA reporting requirements. Please refer to the ARB reporting website for California-specific reporting requirements and additional help.

All CO2 and CO2 equivalent values should be reported with precision to the nearest ton. When reporting CH4 and N2O emissions in tons of each respective gas, CH4 emissions should be reported with two decimal places and N2O emissions should be reported with three decimals places. After factoring in the GWP for CH4 and N2O, the emissions reported for each gas will have a precision on the same order as values reported for CO2 equivalents.
