The table below shows a comparison of emissions by sector from 2008, 2014, and 2021. Several elements of analysis have changed in the 13 years between 2008 and 2021. Operators’ ability to retrieve and report data has improved. State and federal data sources have expanded. The science of GHG warming potentials and associated factor sets has improved. The US Community Protocol for GHG inventories has evolved. The quality of GHG analysis has thus improved with time. Previous years’ data still provides valuable point-in-time snapshots, though the differences in methodology, data inputs, and quality described above cause variability in the outputs.

As noted in the previous table, the 2014 and 2021 inventories include data from additional fields, preventing an “apples to apples” comparison between the total GHG numbers for the three inventories. To assist in comparative analysis, the table below shows line-item comparisons to 2014 and 2021 of usage data and emissions data for all fields included in the 2008 inventory.
