Title: Illinois Sustainable Technology Center Sustainability Seminar Series


1
Illinois Sustainable Technology
CenterSustainability Seminar Series
  • Overview of the Path to Curbing Global Warming
    Becoming Carbon Neutral 

2
Presentation Outline
  • Magnitude of the Problem
  • Blueprint for the Nation
  • Blueprint for Chicago
  • Blueprint for ISTC
  • Outline of Sustainability Seminar Series for this
    Year

3
Magnitude of the Problem
  • Levels of CO2 have increased 25 in the last
    century
  • Global average surface temperature has increased
    by almost 1 degree C since 1900
  • If temperatures rise 1 degree C further
    ecological impacts could include increased risk
    of extinction for 20 percent to 30 percent of
    plant and animal species, widespread coral
    bleaching, etc.

4
Magnitude of the Problem
  • If temperatures rise 2 degrees C further human
    impacts could include
  • increased risk of starvation from lost crop
    productivity in lower latitudes
  • annual coastal flooding that would affect
    millions
  • increased water stress for hundreds of millions
    of people
  • increases in malnutrition increased deaths,
    diseases and injury due to extreme weather
    events increased burden of diarrhoeal
    diseasesand the altered spatial distribution of
    some infectious diseases

5
Potency of Greenhouse Gases
  • Greenhouse Gas 100-Year
    GWPs
  • Carbon Dioxide (CO2) 1
  • Methane (CH4) 21
  • Nitrous Oxide (N2O) 310
  • Sulphur Hexafluoride (SF6) 23,900
  • HFCs Range from 12 to 11,700
  • PFCs Range from 6,500 to 9,200

6
Actions Needed
  • Under a scenario of rapid fossil fuel growth
    trends, the IPCC projects that temperature
  • increases will range from 2.4 to 6.4 degrees
    Celsius by 2100
  • Reduce our global warming pollution the 80
    percent by 2050
  • Stabilize at 450 parts per million (ppm) CO2
  • Limiting expected warming to 2 degrees C

7
Blueprint For The Nation
  • The New Energy Economy Putting America on the
    Path to Solving Global Warming NRDC Issue Paper,
    June 2008
  • McKinseys Roadmap for Transforming Our Energy
    Economy
  • Examines the cost and market potential of more
    than 250 greenhouse gas abatement technologies
  • The US can do its part to stabilize the climate
    at little to no net cost to the economy,
    considering energy-efficiency savings

Sources of Greenhouse Gases in Chicago
  • Buildings account for 70 of emissions
  • Transportation is responsible for 21
  • Industrial emissions and waste account for 9

Blueprint for ISTC
  • Conducted an Energy Audit
  • Calculated our Carbon footprint
  • Applied for Grants Student Energy and
    Sustainability Funds
  • Produce Biodiesel

25
Results of Energy Audit
  • 5 Options, 57,000 annual savings
  • Ventilation Heat Recovery
  • Lighting Upgrade
  • Occupancy Sensors
  • High Efficiency Hot Water Boilers
  • System Recommissioning

26
ISTC Carbon Footprint Project
  1. Secured organizational support
  2. Determined sources to include
  3. Calculated our emissions
  4. Established emissions reduction targets
  5. Reduced and reported our CO2 emissions

27
Step 1Secure Organizational Support
  • ISTC Carbon Footprint Policy
  • Enacted in June 07
  • Operate in an energy efficient way
  • During procurement of Center supplies, include
    energy considerations
  • Educate staff and clients on greenhouse gas
    emission issues

28
Step 2 Determine sources to include
  • Direct Sources
  • Natural gas usage in our boiler
  • Gasoline usage in ISTC owned vehicles
  • Indirect Sources
  • Electricity usage

29
Step 2 Determine sources not to include
  • Business travel by air, rail, taxi or rental car.
  • Employee commuting from home to work.
  • Emission from the manufacture of consumables
    (i.e. paper, pens, etc.)
  • Energy usage in leased office space
  • We felt that this data was too difficult to find.
    Maybe next year!

Step 3 Gather Usage Data (2005)
Natural Gas 96,850 therms
Electricity 1,594,500 kWhr
Gasoline 6,125 gal
31
Step 3 General Formula

Annual Usage x Emission Factor Carbon Emissions
32
Step 3 General Formula

Annual Usage x Emission Factor Carbon Emissions
Natural Gas (therms) 96,850 X
Gasoline (gals) 6,125 X
Electricity (kwhr) 1,594,500 X
33
Step 3 Emission Factors
  • Emission factors help us convert energy usage to
    carbon emissions
  • Where to find them
  • Power Company
  • Department of Energy
  • http//www.eia.doe.gov/oiaf/1605/coefficients.html
  • World Resources Institute
  • http//www.ghgprotocol.org/calculation-tools

34
Many Sources of Electricity CO2 Emission Vary by
Location
35
Emissions From Our Power Company
36
Step 3 Calculations
Annual Usage x Emission Factor / Conversion Factor Carbon Emissions (tons CO2 /yr)
Natural Gas (therms) 96,850 X 11.698 lbs CO2 /therm / 2000 (lbs / ton) 567 tons /yr
Gasoline (gals) 6,125 X 19.564 lbs CO2 /gal / 2000 (lbs / ton) 60 tons /yr
Electricity (kwhr) 1,594,500 X 1.77 lbs CO2 / kWhr / 2000 (lbs / ton) 1411 tons /yr
Total 2038 tons /yr

37
Step 4 Reducing ISTCs Emissions
  • Replace older lights with more energy efficient
    ones
  • Install new controls on fume exhaust systems
  • Use biodiesel made from waste oil
  • Purchase energy efficient equipment
  • Renewable energy

38
Step 5 What does this mean
  • Use an equivalency calculator
  • www.epa.gov/cleanenergy/energy-resources/calculato
    r.html.
  • ISTCs 2038 tons of emissions
  • Equivalent to burning 10 railcars of coal.
  • Can be offset by growing 48,081 tree seedlings
    for 10 years.
