Temperature will increase year-roundTemperature will increase year-round– In summer, highs could increase 3-7°FIn summer, highs could increase 3-7°F
July heat index could rise 10-25°FJuly heat index could rise 10-25°F– In winter, lows could increase 3-10°FIn winter, lows could increase 3-10°F

Two Ways to Combat Two Ways to Combat Climate ChangeClimate Change
Reduce personal carbon footprint Reduce personal carbon footprint (and potentially generate offsets)(and potentially generate offsets)– Turn off the lightsTurn off the lights– Get out of the carGet out of the car– Reduce, reuse, and recycleReduce, reuse, and recycle
Help reduce others’ carbon Help reduce others’ carbon footprints (aka, buy offsets)footprints (aka, buy offsets)

What is a Carbon Offset?What is a Carbon Offset?
1 offset = 1 metric ton1 offset = 1 metric ton** of of greenhouse gases (GHGs) that greenhouse gases (GHGs) that are are voluntarily voluntarily kept out of the kept out of the atmosphereatmosphere– Reductions must be “beyond Reductions must be “beyond
business-as-usual” business-as-usual”
** 1 metric ton = 1.1 U.S. ton 1 metric ton = 1.1 U.S. ton

Three Ways to Create Three Ways to Create OffsetsOffsets
Reduce the burning of fossil fuels Reduce the burning of fossil fuels (oil, gas, coal)(oil, gas, coal)
Store carbon in plants or Store carbon in plants or undergroundunderground
Minimize the amount of GHGs Minimize the amount of GHGs leaked to the atmosphereleaked to the atmosphere

Projects that Reduce Projects that Reduce Fossil Fuel CombustionFossil Fuel Combustion Renewable Energy/FuelsRenewable Energy/Fuels
– e.g., wind farm, landfill gas, biofuelse.g., wind farm, landfill gas, biofuels
Energy EfficiencyEnergy Efficiency– e.g., green building, ENERGY STARe.g., green building, ENERGY STAR®®

Projects that Reduce Projects that Reduce GHG LeakageGHG Leakage

Industrial gas processing and Industrial gas processing and handling improvementshandling improvements– e.g., reducing SFe.g., reducing SF66 leakage from leakage from
electrical transformers, reducing electrical transformers, reducing HFC leakage from A/C units HFC leakage from A/C units

Offsets Must Meet Offsets Must Meet Certain Quality CriteriaCertain Quality Criteria
Must be a real, measurable GHG Must be a real, measurable GHG reductionreduction
Must not be required by lawMust not be required by law
Must be beyond business-as-usualMust be beyond business-as-usual
Must not be financially or otherwise Must not be financially or otherwise feasible without offset salesfeasible without offset sales

Benefits of Creating Benefits of Creating OffsetsOffsets
Can provide funding for energy-Can provide funding for energy-efficient facility upgradesefficient facility upgrades– Less demand for energy = less demand Less demand for energy = less demand
from power plantsfrom power plants– Growing demand for new offset projectsGrowing demand for new offset projects
Can provide good PRCan provide good PR– Promote proactive environmental Promote proactive environmental
initiatives (although beware increased initiatives (although beware increased scrutiny of project)scrutiny of project)

Benefits of Buying Benefits of Buying OffsetsOffsets
Cost-effectively reduce GHG Cost-effectively reduce GHG emissions when can’t reduce emissions when can’t reduce internallyinternally
Provide flexibility for compliance Provide flexibility for compliance programsprograms

Wide Range of Offset Wide Range of Offset PricesPrices
Offset prices range from $0.50-Offset prices range from $0.50-$78/ metric ton$78/ metric ton– Low end prices for Chicago Climate Low end prices for Chicago Climate
Exchange offsetsExchange offsets– High end prices for Kyoto offsetsHigh end prices for Kyoto offsets
Conservatively expect to pay Conservatively expect to pay ~$10/metric ton for a high ~$10/metric ton for a high quality, U.S.-based offsetquality, U.S.-based offset
