File Number: 17-410 <br />Commercial and Industrial emissions from building and process energy use, which accounts <br />for 23% of citywide emissions, showed steep declines to approximately 29% less than 2005 <br />levels. Residential building emissions also dropped 16% from 2005 levels. Variation in <br />weather patterns can influence building energy usage, but efforts by residents, <br />commercial/industrial building owners and businesses, and utilities (as part of the <br />state-mandates and incentive programs under AB 32) have also played a role in improving the <br />energy performance of San Leandro’s building stock. <br />The types of power sources that make up a utility’s electricity generation mix also have had a <br />significant impact on a city’s greenhouse gas emissions in the commercial, industrial and <br />residential sectors. Over the past several years, PG&E’s electric grid has reduced its reliance <br />on carbon-intensive energy sources. PG&E’s power mix in 2015 comprised of approximately <br />25% natural gas, 23% nuclear, 6% large hydro-electric and 30% renewable energy, with 17% <br />remaining from “unspecified” sources. In 2015, PG&E’s electricity created only one-third as <br />many greenhouse gas emissions per kilowatt-hour compared to the industry average and <br />produced over two times the amount of renewable energy than in 2005. <br />Waste diversion policies - mandatory recycling and composting though county-wide <br />regulations - contributed to steep decreases in emissions from the Solid Waste sector. The <br />50% reduction in tons landfilled in 2015 compared to 2005 resulted in a decrease of 60% in <br />emissions from solid waste. Wastewater treatment emissions remained flat between 2005 <br />and 2015 even while San Leandro’s Water Pollution Control Plan (WPCP) decreased its <br />process emissions by 41%. The inclusion of emissions data from the Oro Loma Sanitary <br />district in the 2015 emissions calculation offset the significant upgrades made at the WPCP. <br /> San Leandro Municipal Emissions from 2005 to 2015 <br />Municipal Emissions, in metric tons (MTCO2e): <br />2005: 5,146 <br />2010: 7,413 <br />2015: 6,225 <br />Over the past ten years, San Leandro’s municipal emissions have increased by 21% to <br />approximately 6,225 MT of CO2e from the 2005 baseline of 5,150 MT CO2e. This increase <br />may not reflect actual increase in emissions; improved methods of measurement and <br />calculation as well as new sources counted in 2015 that were not included in the 2005 <br />inventory. 2015 emissions are 16% lower than in 2010 and, while the target for 25% <br />reductions by 2020 has not been met, ongoing energy efficiency and renewable energy <br />projects for city facilities will enable municipal operations to make greater progress towards <br />the 2020 goals. <br />City Buildings and Facilities emissions have decreased significantly since 2005, showing a <br />decrease of 10%. This sector represents approximately 20% of municipal emissions. This <br />decrease is due to the installation of more energy-efficient building equipment in 2010-2012, <br />as well as the cleaner power mix coming from PG&E. Wastewater treatment emissions, which <br />represent 27% of municipal emissions, have decreased by approximately 16% since first <br />Page 4 City of San Leandro Printed on 7/11/2017 <br />22
