8 <br />oxide (N2O) released during the treatment process. The Plant is the largest <br />consumer of electricity for municipal operations and accounts for a large <br />portion of municipal emissions. In 2015, 2,710 metric tons of CO2e were <br />released from wastewater treatment, about the same as previous inventories <br />(2005: 2,706 MT CO2e; 2010 2,703 MT CO2e). <br /> <br />Greenhouse gas emissions also result from the electricity used to clean and <br />supply potable water to the City by EBMUD. The community used 3,092 million <br />gallons resulting in 816 MT CO2e. In total, water and wastewater account for <br />3,526 MT CO2e, or about 0.55% of overall emissions. <br /> <br />The 2015 inventory is not exactly comparable to previous inventories, though, <br />due to the recent inclusion of emissions from wastewater sent to Oro Loma and <br />a new method of categorization. Despite that, it is clear that the largest sector <br />of emissions for San Leandro’s Water Pollution Control Plant, process-related <br />emissions of N2O, has decreased by about 41% over 10 years despite an increase <br />in population in San Leandro. This decrease is almost exactly offset by the <br />energy and process emissions from San Leandro’s wastewater that is processed <br />at Oro Loma’s Wastewater Plant. Thus, overall wastewater treatment emissions <br />appear to remain unchanged despite significant upgrades in energy and <br />processing efficiency. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />34
