President’s Climate Commitment
Initiate the development of a comprehensive plan to achieve climate neutrality as soon as possible
Complete a Greenhouse Gas inventory by January 2009 Within one year of signing this document, complete a comprehensive
inventory of all greenhouse gas emissions (including emissions from electricity, heating, commuting, and air travel) and update the inventory every other year thereafter.
Develop an Action Plan by January 2010 Within two months of signing this document, create institutional
structures to guide the development and implementation of the plan. Within two years of signing this document, develop an institutional
action plan for becoming climate neutral
Initiate two or more items from a list of tangible actions to reduce greenhouse gases while the more comprehensive plan is being developed

Demand Side – New Buildings (LEED)
Leadership in Energy and Environmental Design (LEED) by USGBCAchieve LEED-NC Silver rating
Focus on Energy Reduction points
Beginning in 2009, U of M has 1% additional square footage per year as Silver12% Silver buildings by 2020 lowers CO2 emissions by 3.84%Costs $8,692,458 for each 1% CO2 reduction in 2009 (*could have no cost)

Demand Side – New Buildings (ENERGY STAR)
ENERGY STAR building program by US EPA & US DOEENERGY STAR buildings perform better than 75% of peers
On average, consume 40% less energy and emit 35% less CO2
Beginning in 2009, U of M has 1% additional square footage per year as ENERGY STAR12% ENERGY STAR buildings by 2020 lowers CO2 emissions by 4.20%Negligible cost for each 1% CO2 reduction in 2009
