Climate Action Plan

u The Climate Action Plan is divided into three phases:

u Phase I (2010-2015): reduce carbon emissions to 15 percent below 2005 levels by 2015.

u Phase II (2015-2020): reduce carbon emissions to 25 percent below 2005 levels by 2020.

u Phase III (2020-2050): achieve carbon neutrality by 2050.

Scopesu Scope 1:

u On-campus stationary sources (Central Energy Plant)

u Natural gas, propane, coal

u Direct transportation sources (University Fleet)

u Refrigerants/chemicals

u Agriculture

u Scope 2:

u Purchased electricity

u Scope 3:

u Student, faculty, staff commuting

u Directly financed travel (reimbursements for flights/gas)

u Solid waste Courtesy of Clean Air Cool Planet

YearScope 3 Emissions Scope 2 Emissions Scope 1 Emissions

Scope 3 emissions decreased by 2,029 MT eCO2 from FY16 to FY17

Climate Action Planu 2005 baseline: 127,518 MT eCO2

u 2015 target: 108,390 MT eCO2 (15% decrease)

u Actual: 119,019 MT eCO2 (7% decrease)

u Since 2010, there has been a 6% increase in emissions

u 2020 target: 95,638 MT eCO2 (25% decrease)

u 2017: 150,382 MT eCO2

u Eliminate 54,743 MT eCO2 over next 3 years (57% decrease)

Conclusionsu Increase in total emissions since FY 2015 and FY 2016

u Due to an 9% increase in Scope 2

u Electrical suppliers use a large amount of coal

u Increase in total building space/research building space

u Two buildings came on line (High Bay and STEM)

u Due to a 42% increase in Scope 1

u Shift from natural gas to coal
