SUMMARY
The Council-adopted General Plan includes greenhouse gas (GHG) emission reduction targets for the Hayward community. This report provides the results of the calendar year 2022 inventory and compares it to the previous eight inventories. Table 1 summarizes the emissions totals for six sectors - electricity, natural gas, transportation (includes public transit), off-road vehicles, waste, and water and wastewater. Emissions are displayed in metric tons of carbon dioxide equivalent (MTC02e). The table shows that as of 2022, emissions have been reduced by 37.3% since 2005.
As the largest contributor to community GHG emissions, trends in on-road transportation highly impact the inventory. Following the decrease in transportation emissions due to the COVID-19 pandemic in 2020, staff expected emissions to increase in 2021 and 2022 as restrictions eased and pre-pandemic activities resumed. Despite 2022 being the first full year without pandemic-related restrictions, total emissions from 2021 to 2022 only increased by 0.2% from 37.5% to 37.3% above 2005 levels. The relatively consistent emissions between 2021 and 2022 could be attributed to a shift towards increased hybrid and remote work following the pandemic.
