Introduction
● La Follette School of Public Affairs
● Special Thanks to Jeanne Hoffman
● International Council for Local
Environmental Initiatives (ICLEI)
● Goals and Importance
Inputs
Sectors for community emissions analysis
● Madison energy
● Residential energy
● Commercial energy
● Industrial energy
● Transportation and mobile devices
● On- and off- road transportation
● Public transportation: public transit
● Waste
● Solid and water waste generated by households and
businesses
Data Collecting
● Data were gathered from state and local governmental
departments, as well as private organizations.
● Energy: Madison Gas and Electric (MGE) & Alliant Energy
● Transportation: Madison Metro Transit, DNR and Regional Airport
● Waste: Dane County Public Works and Madison Metropolitan
Sewerage District
● Demographic data: U.S. Census Bureau
Results
● 2012 4,438,398 metric tons of CO2e compared to 3,954,293
metric tons in 2010
● 18.5 metric tons per person
WI average 16.7 metric tons in 2011
Madison Resident
(18.5 metric tons)
U.S.
(16.9 metric tons)
Wisconsin Resident
(16.7 metric tons)
Top 3 Energy Sectors Remain the Same
● Commercial energy, transportation, and residential energy
remain the top 3 emitters.

CO2e Reduction Strategies
● Commercial Energy
– Benchmarking
● Transportation
– Bus Rapid Transit
● Residential Energy
– Solar Electricity
Generation
Commercial Building Energy Benchmarking
Requirement that owners of buildings with more than a
specified amount of square footage must publicly report
information regarding building energy consumption.
● Energy Star Portfolio Manager
● 35,000 Buildings tracked from 2008 - 2011
● 2.4% Annual reduction
● 7% total reduction over study period
● Study of California IOUs Program
● 0.13 kWhs/square foot
● 0.002 therms/square foot

Residential: Solar Energy
● The City of Madison has been promoting
solar technology at the local level since
2007
● MadiSUN program
Forecasting Logistics
● Target 1 Megawatt by 2020 (Start year 2015)
● Average cost for installation $5.00/W
● $620,000 annual spending required for constructions
through 2020
● Focusing on solar energy in residential sector
(Using 2012 Residential price for electricity $.1188/kWh)
● Expecting 200 kW installed capacity will be annually deployed
through 2020
