File Number: 17-410 <br />The City of San Leandro is committed to the measurement and reduction of greenhouse gas <br />emissions within its management and control. The City has conducted inventories every five <br />years since 2005 to continuously evaluate the scale and scope of emissions. Greenhouse gas <br />inventories provide policymakers with information necessary to assess the existing state of <br />carbon emissions within their jurisdictions and to make decisions on where to focus mitigation <br />efforts. The community inventory represents all the energy used and waste produced within <br />the City of San Leandro and its contribution to greenhouse gas emissions. The municipal <br />inventory is a subset of the community inventory, and includes emissions derived from internal <br />government operations. <br />Greenhouse gases are defined as carbon dioxide (CO2), methane (CH4), nitrous oxide <br />(N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulfur hexafluoride (SF6). <br />Carbon dioxide equivalent (CO2e) is a unit of measure that normalizes the varying climate <br />warming potential of the six greenhouse gas emissions. For example, one metric ton of <br />methane is equivalent to 21 metric tons of CO2e. One metric ton of nitrous oxide is equivalent <br />to 210 metric tons of CO2e. The global warming potential of these gases was determined in <br />the International Panel on Climate Change (IPCC) 4th Assessment. <br />San Leandro Community Greenhouse Gas Emissions Inventory 2005 to 2015 <br />Community Emissions, in metric tons (MTCO2e): <br />2005: 675,288 <br />2010: 612,376 <br />2015: 636,172 <br />In 2015, San Leandro’s community emissions were 636,172 metric tons (MT) CO2e, a <br />reduction from the 2005 baseline of 675,288 MT CO2e by 39,116 MT CO2e. Municipal <br />operations and facilities contributed 6,225 MT CO2e, about 1% of the total inventory. The <br />largest sectors contributing to community emissions are transportation (60%), commercial and <br />industrial energy use (23%), and residential energy use (13%). Solid waste and wastewater <br />emissions contributed only about 4% of total emissions. <br />This mixed result can be attributed to a reduction in energy usage during the 2008-2010 Great <br />Recession - a period of decreased economic activity with greater vacancies in San Leandro’s <br />building stock, a slowdown in building and goods shipments - and an uptick in development <br />and population growth between 2010 and 2015. The surge in transportation, especially in the <br />through-traffic of commercial trucks and passenger vehicles, are outside the direct control of <br />the City of San Leandro. <br />The largest source of carbon emissions in San Leandro is transportation, accounting for 60% <br />of all community emissions. Vehicle miles travelled (VMT) have increased over the past few <br />years and overall transportation emissions, after declining slightly in 2010, went up <br />significantly between 2010 and 2015. Analysis of the VMT data shows that much of this <br />increase is due to heavy-truck traffic through San Leandro. As the economy has improved, <br />goods movement up and down the I-880 corridor has increased transportation-related <br />emissions occurring within city limits. <br />Page 3 City of San Leandro Printed on 7/11/2017 <br />21
