


Why be concerned about climate
change?
What can be done to lessen impact of
climate change?
What role do carbon offsets play?
How can offsets help pay for facility
improvements?

Climate Change in Central TX

Weather Impacts

Water Resource Impacts

Human Health Impacts
3
Weather Impacts in Central TX

Temperature will increase year-round
– In summer, highs could increase 3-7°F
 July heat index could rise 10-25°F
– In winter, lows could increase 3-10°F
 Fewer freezes expected

Precipitation changes are less clear
– Changes in average precipitation uncertain
– More frequent flooding with longer droughts
4
Water Impacts in Central TX


Coastal sea level rise of 1.5-4 ft. could
lead to inland migration
Increased evaporation of surface water
up to 35%
– Less water available for groundwater
recharging
– Less water available for crop irrigation

Crop yields could be reduced by up to 68%
5
Health Impacts in Central TX

Increased heat and pollution related
illnesses and deaths
– More intense heat waves
– More Ozone Action Days

Increased insect related illnesses and
deaths
– Expanded range/duration for mosquitoes
and other disease-carrying insects
6
Two Ways to Combat
Climate Change

Reduce personal carbon footprint
(and potentially generate offsets)
– Turn off the lights
– Get out of the car
– Reduce, reuse, and recycle

Help reduce others’ carbon footprints
(aka, buy offsets)
7
What is a Carbon Offset?

1 offset = 1 metric ton* of greenhouse
gases (GHGs) that are voluntarily kept
out of the atmosphere
– Reductions must be “beyond business-asusual”
*
1 metric ton = 1.1 U.S. ton
8
Three Ways to Create Offsets



Reduce the burning of fossil fuels (oil,
gas, coal)
Store carbon in plants or underground
Minimize the amount of GHGs leaked
to the atmosphere
9
Projects that Reduce Fossil
Fuel Combustion

Renewable Energy/Fuels
– e.g., wind farm, landfill gas, biofuels

Energy Efficiency
– e.g., green building, ENERGY STAR®

Industrial Efficiency
– e.g., cogeneration, operational upgrades

Transportation Efficiency
– e.g., signal synchronization, mass transit
10
Projects that Store Carbon

Tree Planting
Avoided Deforestation

Improved Agriculture Practices

– e.g., reduced fertilizer use, no till
11
Projects that Reduce GHG
Leakage


Natural gas pipeline improvements
Industrial gas processing and handling
improvements
– e.g., reducing SF6 leakage from electrical
transformers, reducing HFC leakage from
A/C units
12
Offsets Must Meet Certain
Quality Criteria

Must be a real, measurable GHG reduction

Must not be required by law

Must be beyond business-as-usual


Must not be financially or otherwise feasible
without offset sales
Must not be double-counted
13
Benefits of Creating Offsets

Can provide funding for energy-efficient
facility upgrades
– Less demand for energy = less demand from
power plants
– Growing demand for new offset projects

Can provide good PR
– Promote proactive environmental initiatives
(although beware increased scrutiny of project)
14
Energy Efficiency Example

HVAC replacement + reflective roof
15
Energy Efficiency Example
(cont.)



Saved 291 kW of peak demand and
387,000 kWh of energy
Offset revenue = $29,500 over 15
years at $10/metric ton
vs.
Austin Energy rebate = $114,500
16
Benefits of Buying Offsets



Cost-effectively reduce GHG emissions
when can’t reduce internally
Provide flexibility for compliance
programs
May have secondary environmental
and/or social benefits
17
Wide Range of Offset Prices

Offset prices range from $0.50-$78/
metric ton
– Low end prices for Chicago Climate
Exchange offsets
– High end prices for Kyoto offsets

Conservatively expect to pay
~$10/metric ton for a high quality,
U.S.-based offset

Demand for Offsets is on the
Rise


1st recorded carbon offset in 1989
Market began picking up steam after U.S.
rejected Kyoto in 2001
– Since 2002, number of offset providers has
jumped 220%

And really took off in past few years
– B/t 2005-2006, offset sales skyrocketed by
nearly 200%
– B/t 2006-2007, sales expected to at least double
20
Regulations will Further
Increase Demand in U.S.

3 regional cap-and-trade programs
– Regional Greenhouse Gas Initiative
– Western Climate Initiative
– Midwestern Greenhouse Gas Accord

Numerous state carbon regulations
– CA, OR, MA, FL, etc.

Imminent federal carbon regulation
– Demand for offsets in the 1st year of leading
cap-and-trade proposal could be over 30X the
current volume of offsets!
21
Recommendations

Evaluate your facilities for GHG savings
potential
– Before you can reduce, must measure

Make sure they’re certified to a nonproprietary standard to ensure quality
– VCS, CCAR, Gold Standard, CDM

Record offset transactions with a GHG
registry to ensure credit
– ERT GHG Registry, CCAR, CCX
