Objectives

• Analyze the energy use and greenhouse gas emissions of Lucas County and City of Toledo governments

• Recommend future actions

2

Terminology

Energy Inventory• kWh or BTU

• Cannot differentiate clean energy

GHG Inventory• Metric Tons Carbon

dioxide equivalence (MT CO2e)

• Accounts for clean energy

(Direct) (Indirect) (Optional, not considered)

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

8

Common Greenhouse Gases

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 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

Emissions from Landfill

Lucas County• No landfill

City of Toledo

• Hoffman road landfill• Servicing the residents of Toledo until the

year 2026

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.
