Notes: GWP = global warming potential; MMTCO2e = million metric tons of carbon dioxide equivalent 1California’s first 1990 GHG emissions inventory was prepared in 2007 by ARB using GWP values from the IPCC Second Assessment Report. All other inventory years shown use GWP values from the IPCC Fourth Assessment Report. 2Includes both in-state electricity generation and out-of-state imported electricity. 3High GWP and Recycling and Waste sectors were included in the Industrial sector for the 1990 inventory only. 4Totals may not sum exactly due to rounding.

The LGOP resulted in higher emissions in 2010 in this category because of the types of emissions included and how the wastewater emissions were calculated.

All emissions shown in 2010-2013 are consistent with C/CAG RICAPS data. 2Emissions associated with these specific activities in 2005 either were not included or were bundled in with other sectors in the updated 2005 inventory. 3There are no existing landfills within the city limits. Therefore, no waste-in-place emissions exist in the City’s inventories for 2005-2013. Source: City of Millbrae, 2010; C/CAG 2015; compiled by Ascent Environmental, 2016.
