<br />Interim Emissions
<br />In addition to the 2005 GHG inventory, the City prepared community-wide GHG emissions for the
<br />years 2010, 2015, and 2017. These interim years show changes to GHG emissions since the 2005
<br />baseline.
<br />GHG emissions have declined steadily from 2005 levels. In 2017, GHG emissions totaled 573,580
<br />MTCO2e, a decrease of 20 percent from 2005. GHG emissions from energy, transportation, waste,
<br />and water and wastewater declined. The decrease in non-residential energy is a combination of
<br />sources of electricity being much cleaner in 2017 than in 2005, although there was also a significant
<br />decline in non-residential natural gas use that may be a result of changing economic activities or
<br />differences in PG&E reporting. The decline in residential energy use is primarily the result of cleaner
<br />electricity sources. Emissions associated with solid waste declined due to reductions in trash being
<br />thrown out, likely due to more robust recycling and composting programs as well as increasing
<br />awareness around waste reduction. BART and off-road emissions increased, likely a result of San
<br />Leandro’s growing population, higher rates of construction activities, and increased BART ridership.
<br />Table 2 shows the change in GHG emissions from 2005 to 2017, and the activity data by subsector
<br />for the four inventory years.

<br />In 2017, transportation remained the largest source of GHG emissions, accounting for
<br />approximately 60 percent of the City’s total. Nonresidential energy was the second-largest source
<br />of GHG emissions, equaling approximately 15 percent of the community total, followed by
<br />residential energy at 13 percent. Waste was the fourth-largest source of GHG emissions at 6
