Sources and Notes:
74
MWCOG conducts community inventories for the region and all its member local jurisdictions. In order to have comparable inventories that are consistent from the top down and bottom up, the same data sources and methodologies are used across all the inventories. Data comes from sources that are regularly available over the years to compare inventories across past, present, and any future inventories. MWCOG inventories have been verified as compliant with national and global protocols for greenhouse gas (GHG) accounting. MWCOG follows the U.S. Communities Protocol (USCP) as the methodology for these inventories. The data presented above includes the leading local data inputs called for by the USCP. The local data inputs and emission factors influence the resulting GHG emissions (see Output tab).

Note: Washington Gas provided zip code level account and consumption data from 2009 - 2016 with an "unassigned" category to protect the privacy of some accounts. Since 2017, an "unassigned" category has not been provided and those accounts and consumption are attributed to the jurisdiction in which they reside. This does not affect the overall consumption and emissions for the region when comparing across inventory years; however, it may be one reason for a noticable increase in 2018 consumption and emissions at the individual jurisdiction level.
