3 <br />This mixed result can be attributed to a reduction in energy usage during the 2008-2010 Great Recession – a period of <br />decreased economic activity with greater vacancies in San Leandro’s building stock and associated slowdown in building and <br />goods shipments – followed by an uptick in development and population growth between 2010 and 2015. The surge in <br />transportation, especially in the through-traffic of commercial trucks and passenger vehicles, are outside the direct control <br />of the City of San Leandro. <br />The largest source of carbon emissions in San Leandro is transportation, <br />accounting for 60% of all community emissions. Vehicle miles travelled (VMT) <br />have increased over the past few years and overall transportation emissions, after <br />declining slightly in 2010, went up significantly between 2010 and 2015. Analysis <br />of the VMT data shows that much of this increase is due to heavy-truck traffic <br />through San Leandro. As the economy has improved, goods movement up and <br />down the I-880 corridor has increased transportation-related emissions occurring <br />within city limits. <br />Commercial and Industrial emissions from building and process energy use, which <br />accounts for 23% of citywide emissions, showed steep declines to approximately <br />29% less than 2005 levels. Residential building emissions also dropped 16% from 2005 levels. Variation in weather patterns <br />can influence building energy usage, but efforts by residents, commercial/industrial building owners and utilities (as part of <br />the state-mandates and incentive programs under AB 32) have also played a role in improving the energy performance of <br />San Leandro’s building stock. <br />The types of power sources that make up a utility’s electricity generation mix also have had a significant impact on a city’s <br />greenhouse gas emissions in the commercial, industrial and residential sectors. Over the past several years, PG&E’s electric <br />grid has reduced its reliance 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% remaining from “unspecified” <br />sources. In 2015, PG&E’s electricity created only one-third as many greenhouse gas emissions per kilowatt-hour compared <br />to the industry average and produced over two times the amount of renewable energy than in 2005. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />383,954 <br />142,883 <br />85,589 <br />20,220 3,526 <br />0 <br />50000 <br />100000 <br />150000 <br />200000 <br />250000 <br />300000 <br />350000 <br />400000 <br />450000 <br />Comparison of Sectors, 2015 <br />(MT CO2e) <br />Transportation <br />Commercial and Industrial Energy <br />Residential Energy <br />Solid Waste <br />Water and Wastewater <br />0 <br />10,000 <br />20,000 <br />30,000 <br />40,000 <br />50,000 <br />Solid Waste Water & WastewaterMT CO2eWaste and Wastewater, 2005-2015 <br />2005 2010 2015 <br />29
