2. Introduction ●La Follette School of Public Affairs ● Special Thanks to Jeanne Hoffman ● International Council for Local Environmental Initiatives (ICLEI) ● Goals and Importance

3. 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

4. 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

5. Results ● 2012 4,438,398 metric tons of CO 2 e 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)

6. Top 3 Energy Sectors Remain the Same ● Commercial energy, transportation, and residential energy remain the top 3 emitters.

7. CO 2 e Emissions by Sector in 2012

8. CO 2 e Emissions by Source in 2012

9. Business as Usual Projection

10. CO 2 e Reduction Strategies ●Commercial Energy – Benchmarking ●Transportation – Bus Rapid Transit ●Residential Energy – Solar Electricity Generation

11. 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

12. Commercial Building Energy Benchmarking At a threshold of 25,000 square feet ●5,859 metric tons of CO 2 e per year ●1,233 passenger vehicles per year ●535 residential homes per year Size Included in Ordinance Total Sq.

15. Residential: Solar Energy ●The City of Madison has been promoting solar technology at the local level since 2007 ●MadiSUN program

16. 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
