SUBJECT 2020 Greenhouse Gas Emissions Inventory
RECOMMENDATION
That the Council Sustainability Committee (CSC) reviews and comments on this report.
SUMMARY
The Council-adopted General Plan includes greenhouse gas (GHG) emission reduction targets for the community. This report provides the results of the calendar year 2020 inventory and compares it to the previous six inventories. Table 1 summarizes the emissions totals for the eight sectors – electricity, natural gas, transportation, public buses (AC Transit), BART, off-road vehicles, waste, and water and wastewater. Emissions are displayed in metric tons of carbon dioxide equivalent1 (MTC02e). The table shows that, in 2020, emissions were reduced by 42.7% since 2005. In 2020, the largest reductions occurred in the transportation sector due to the stay-at-home orders and economic disruptions related to the COVID-19 pandemic.

1 Carbon dioxide is not the only gas that contributes to climate change. Each greenhouse gas causes varying amounts of warming. For example, one ton of methane (CH4) causes the same amount of warming as 23 tons of CO2 (1 ton of CH4 = 23 tons CO2e). To simplify reporting, it is standard practice to report carbon equivalent emissions (CO2e) as opposed to the actual emissions of each gas.
