4 <br />Waste diversion policies – mandatory recycling and composting though county-wide regulations – contributed to steep <br />decreases in emissions from the Solid Waste sector. The 50% reduction in tons landfilled in 2015 compared to 2005 resulted <br />in a decrease of 60% in emissions from solid waste. Wastewater treatment emissions remained flat between 2005 and 2015 <br />even while San Leandro’s Water Pollution Control Plan (WPCP) decreased its process emissions by 41%. The inclusion of <br />emissions data from the Oro Loma Sanitary district in the 2015 emissions calculation offset the significant upgrades made at <br />the WPCP. <br />Over the past ten years, San Leandro’s municipal emissions <br />have increased by 21% to approximately 6,225 MT of CO2e <br />from the 2005 baseline1 of 5,150 MT CO2e. This increase <br />may not reflect actual increase in emissions; improved <br />methods of measurement and calculation as well as new <br />sources counted in 2015 that were not included in the 2005 <br />inventory. 2015 emissions are 16% lower than in 2010 and, <br />while the target for 25% reductions by 2020 has not been <br />met, ongoing energy efficiency and renewable energy <br />projects for city facilities will enable municipal operations to <br />make greater progress towards the 2020 goals. <br />City Buildings and Facilities emissions have decreased <br />significantly since 2005, showing a decrease of 10%. This <br />sector represents approximately 20% of municipal <br />emissions. This decrease is due to the installation of more <br />energy-efficient building equipment in 2010-2012, as well as <br />the cleaner power mix coming from PG&E. Wastewater treatment emissions, which represent 27% of municipal emissions, <br />have decreased by approximately 16% since first accurately measured in 2010. <br />Substantive increases in city emissions have only been noted in one sector: the city’s vehicle fleet (representing 24% of <br />emissions) increased by 20% since 2005. Staff is taking a closer look at the data associated with these percentages, as the <br />number of fleet vehicles/mobile equipment has stayed flat between 2005-2015, and with the State-mandated diesel <br />retrofits having been installed prior to 2010. <br />Conversely, Streetlights and Traffic Signals show reductions of 18% since 2005, due to the partial conversion of some <br />streetlights (14%) and all traffic signals to LEDs in 2012. The remaining 86% of streetlights are being retrofitted to smart <br />controllers and LED light fixtures in 2017 through a guaranteed energy savings contract with Climatec, as are City <br />buildings/parks interior/exterior lighting, which will result in greater reductions in emissions in the next inventory. <br /> <br /> <br /> <br />1 Updated totals based on methodology updated in 2014 by StopWaste <br />0 500 1000 1500 2000 2500 <br />Transit Fleet <br />Solid Waste <br />Streetlights <br />Employee Commute <br />Buildings and Facilities <br />Vehicle Fleet <br />Wastewater Treatment <br />Municipal Emissions by Sector 2005-2015 <br />2015 2010 2005 <br />30
