1 Greenhouse Gas (GHG) Management An introduction Tim Holmes, P.E. Kenwood Energy Energy Consulting Services Kenwood Energy P.O.Box 692 Kenwood, CA (707)

2 Green House Gases Kenwood Energy Energy Consulting Services A diagram to help explain the process of global warming and how greenhouse gases create the "greenhouse effect." Main gases are: carbon dioxide (CO2) methane (NH4) nitrous oxide CFC’s

3 Global Warming Potential Kenwood Energy Energy Consulting Services The Global Warming Potential (GWP) of methane is 21 while the GWP of CO 2 is 1. This means that one ton of methane has 21 times the potential effect as does CO 2.

4 Human Effect Kenwood Energy Energy Consulting Services  Fossil Fuels - for energy and transportation, includes: coal, natural gas, propane, gasoline, diesel, etc.  GHG’s are released when burned  Carbon trapped for 250 million years in the form of coal, oil etc.  Land Use Practices  Deforestation, agriculture & landfills  Production of nitrogen based fertilizers  Leaking air conditioners and refrigerators

5 Global Warming Effect Kenwood Energy Energy Consulting Services  Warmer oceans, melting polar ice-caps & glaciers  an increase in storm intensity  rising sea levels  An increase in heat waves  heatstroke, heart attacks and other ailments aggravated by the heat  Other health concerns  malaria and dengue fever spreading

6 The Solution? Kenwood Energy Energy Consulting Services

7 Assembly Bill - 32 Kenwood Energy Energy Consulting Services  AB 32 institutes a mandatory limit (cap) on GHG pollution  Reduce GHG emissions in California to 1990 levels by the year 2020, or 25% below forecasted levels.

8 AB 32 Goals Kenwood Energy Energy Consulting Services Design regulations Ensure equity across economic classes Ensure early implementers are treated fairly Work with Federal & State air quality Consider cost effectiveness burden Societal benefits Minimize administrative burden Minimize leakage Consider all gases Emergency provisions to adjust the applicable deadlines if needed

9 AB 32 Timeline Kenwood Energy Energy Consulting Services By July 1, form Environmental Justice and Economic & Technology Advancement advisory committees By July 1, adopt early action measures that can be adopted and implemented before January 1, 2010 By Jan 1, adopt regulations for mandatory GHG emissions reporting Jan 1, adopt plan indicating how emission reductions will be achieved via regulations, market mechanisms, etc. During draft rule language to implement its plan and hold public workshops During 2010 conduct series of rule-makings, adopt GHG regulations and market mechanisms Jan 1, complete major rules and market mechanisms Jan 1, GHG rules and market mechanisms adopted - legally enforceable Dec 31, Deadline for achieving 2020 GHG cap For more information -
