Equivalent carbon dioxide (CO2e)
• There are 18 long acting greenhouse gases
• Each has unique thermal properties
• Some affect atmospheric temperature more than others
• The warming potential of each gas is used to determine CO2e
• CO2e is measured in metric tons

Putting CO2e into Perspective
• The Toledo built Jeep Liberty has a highway fuel economy of 22 mpg according to the EPA.
• It would need to be driven about 76 million miles to generate 30,400 metric tons of CO2e
How far is 76 million miles?
• ⅘ of the distance between Earth and the Sun
• 159 round trips to the Moon
• 9,960 round trips from Toledo to Anchorage, AK

Methods to Reduce Emissions from Water Treatment
• Energy generationRecover methane from anaerobic digestion process
• Reduce loading– High efficiency toilets– Composting toilets– Low-flow showerheads and faucets– Use of gray water– Use of rain gardens

Methods to Reduce Emissions from Facilities
Lucas County Remotely controlled facility system
projected to reduce energy use by 15-20%
Boiler improvements at county complex 701 Adams to increase energy efficiency
City of Toledo 1 Megawatt First-Solar
Photovoltaic Plant by August 2011 Decrease facilities energy use by
10% by December 2012

Methods to Reduce Emissions from Vehicles
• Procurement policy
• Vehicle/engine replacement on oldest models • External technologies
– anti-idling– retrofit

Methods to Reduce Emissions from Traffic Signals
Replaced all traffic signals with LED bulbs in 2003, reduced energy use by 80% per signal. (Lucas County)
All stoplights with LED bulbs by Dec. 2011, 65% complete. (City of Toledo)
• Consider roundabouts at intersections.– Roundabouts reduce emissions created from signals, idling,
and automobile wrecks

Methods to Reduce Emissions From Landfill
Improved recycling in County managed facilities from 68% to 94%. (Lucas County)
Recycling tonnage is up 300% since 2009. (City of Toledo) Built combined generation plant at Bayview Wastewater
Treatment Plant, runs on landfill gas captured on-site and at Hoffman Road Landfill, reduced CO2e emissions by 70% since 2010. (City of Toledo)
• Create a composting station within Lucas County.
