Climate Change Goals for the Metropolitan
Washington Area
Climate Change Steering Committee February 27,
2008 Joan Rohlfs, MWCOG/DEP
2
Regional Goals Ways to Get There
  • Propose Short-Term Goal (2012)
  • Low Hanging Fruit
  • Interim Goal for 2020 20 Below 2005
  • Actions to Reach Goal
  • Adoption of Long Term Goals (2050)
  • Policies to Reach Goal

Regional Short Term Goal 2012

Long Term and Short Term Goals
  • Long Term Goals Needed to Stabilize Climate
  • Spur investment in new technology
  • Incentive for technological innovation
  • Short Term Goals to Insure Immediate Progress
  • Analyze strategies using existing technology
  • Nearer term year is easier to comprehend,
    anticipate

6
Local Government Short Term Goals
  • Cool Counties agreement Stop emissions growth
    in 2010
  • Mayors Agreement Reduce 7 below 1990 by 2012

7
Proposed Short Term Goal 2012
  • Proposed goal Reduce 7 by 2012
  • 2005-2012 Emissions expected to increase by 7
  • Achievement of 7 reduction goal by 2012 would
    return regional emissions to 2005 levels

8
Low Hanging Fruit
9
Individual Actions
  • Individuals contribute an estimated 7 tons CO2e
    per year
  • Residential energy use (37)
  • Appliance use, AC and heating
  • Transportation (63)
  • Personal car use, mass transit, air travel

Individual Contribution to GHG Emissions
11
Individual GHG Emissions
  • Individuals contribute about 1/3 of CO2 emissions
    in the U.S.
  • Individuals can play an important role in
    achieving short and long term targets
  • Some behaviors can be modified to generate large
    emission reductions (low hanging fruit)

12
Transportation
Reduction
  • Buy more efficient car
  • Carpool w/ 2 others
  • Cut shopping trips in ½
  • Alter driving habits
  • Get frequent tune-ups
  • Maintain tire pressure

Household Energy Reduction
Reduction
  • Weatherize house
  • Install efficient HVAC
  • Reduce inside temp to 68o
  • Install efficient water heater, reduce by 20o
  • Install efficient appliances
  • Change bulbs to CFL

Impact of 60 Reduction in Consumer Emissions
by 2012
15
60 Reductions from Consumers
  • Assumes 2012 BAU emissions
  • 33 percent are consumers
  • Consumers can reduce by 60
  • BAU is 82.3 million MT
  • Reductions would be 16.3 million MT
  • Equivalent to about 20 percent from overall BAU.

16
Midterm Goal 2020How to get there
17
Example Transportation Scenario for 2020
  • Transportation Emissions
  • 2005 to 2020 Increase 24.6
  • Reduction Goal Reduce 20 below 2005
  • Reduction Measures
  • CAFÉ Standards Reduce 20.0
  • 55 mpg by 2020 Reduce 5.1
  • VMT limit (?)

How to Get 20 Reduction by 2020

Long Term Goal 2050
21
IPCC Stabilization Scenario- 2050
  • IPCC recommends reduction in global CO2 emissions
    in 2050 of 50-85 (of 2000 emissions
  • Stabilization defined as CO2-eq concentration at
    445-490 ppm,
  • Global mean temperature increase kept at 2.0-2.4o
    C

22
Proposed Long Term Regional GHG Reduction Goal
70 below 2005 by 2050
  • Based on science in IPCC Report and consistent
    with the Warner Lieberman bills reduction goals

List of Actual and Potential Government Programs
to Reduce GHG Emissions
  • Federal Measures
  • Energy Bill of 2007 (CAFÉ standards, EEE)
  • Energy Efficient appliance standards
  • Establish price and trading for carbon emissions
  • Limit CO2 emissions from power plants, motor
    vehicles
  • Invest in Renewable energy technology (solar,
    wind, hydro)
  • Support nuclear energy research
  • State Measures
  • CAL LEV limits on mobile CO2 emissions
  • RGGI
  • Renewable Porfolio Standards (RE as of Energy
    Efficiency goals)
  • Require GHG emissions analysis as part of
    Environmental Impact analyses
  • Local
  • Purchase of alternative/renewable energy
  • Increase tree canopy
  • LED traffic lights

Federal
State
Local
26
Recommendations
  • Adopt Regional Climate Change Goals
  • 2012 Reduce GHG emissions by 7
  • 2020 Reduce GHG emissions by 20 below 2005
  • 2050 Reduce GHG emission by 70 below 2005
