1. Climate Change Workshop: CIWMB GHG Reduction Measures Strategic Policy Development Committee May 8 th, 2007 Judith Friedman, CIWMB

2. 2 Workshop Agenda Purpose: Collaborative workshop to discuss CIWMB climate change activities.  Presentations on background, technical information and perspectives.  Discussion of “Measures” that can help CIWMB meet GHG emission reduction strategies.

3. 3 Workshop Agenda  Presentations on background, technical information and perspectives. –Morning Session 1 – Introduction –Agency Overview – Eileen Tutt, Cal/EPA –ARB Role – Chuck Shulock, CARB –Overview of Climate Change Activities at the CIWMB – Judith Friedman  Discussion of “Measures” that can help CIWMB meet GHG emission reduction strategies.

4. 4 EO S-3-05 and AB 32 Executive Order Established Statewide GHG Reduction Targets: By 2010, Reduce to 2000 Emission Levels* By 2020, Reduce to 1990 Emission Levels** By 2050, Reduce to 80% Below 1990 Levels * Equals 59 Million Tons Emission Reductions, 11% Below BAU ** Equals 145 Million Tons Emission Reductions, 25% Below BAU AB 32 requires CARB to Establish a GHG cap for 2020 by January 1, 2008.

5. 5 What are Greenhouse Gases (GHGs)? Carbon dioxide(CO 2 )1 Methane(CH 4 )23 Nitrous oxide (N 2 O)296 Hydroflurocarbons (HFCs)120-12,000 Carbon tetrafluoride (CF 4 )5,700 Hexafluorothane (C 2 F 6 )11,900 Perfluorobutane (C 4 F 10 )8,600 Perfluorohexane (C 6 F 14 )9,000 Sulfur hexafluoride (SF 6 )22,200 Global Warming Potential (CO 2 e)

6. 6 Climate Change Strategies  Achieve 50% Statewide Recycling Reduce GHG emissions associated with energy-intensive material extraction and production by increasing recovery of recyclables. Zero Waste / High Recycling Increase recovery of recyclable materials from landfills and create marketable products from organic materials.  Landfill Methane Capture Capture methane from landfills via gas recovery systems.

7. 7 Relationship to Solid Waste  Waste is important source of GHG emissions  Waste activities account for approximately 3% of total U.S. GHG emissions  Waste-related actions result in emission reduction benefits that are realized across multiple industrial sectors

8. 8 A Product’s Life Cycle (source: Oorbeck, 2006) Manufacturing Packaging & Distribution Product Use End of Life Pre-manufacturing Raw Materials Extraction REUSE At each life cycle stage there is resource and energy consumption RECYCLING

9. 9 Recycling Energy Savings (Source Henry Ferland, USEPA)

10. 10 Tools Waste Reduction Model (WARM)  Assess GHG and energy impacts of waste reduction activities  Accepts user- specific inputs and provides individualized results  Available online –www.epa.gov/mswclimate (under “TOOLS”)

11. 11 Organics in the Waste Stream

12. 12 Organics Focus at CIWMB  Look at organic materials management from a Lifecycle Analysis approach  Consider array of waste management options and how each reduces GHG emissions while increasing diversion at the lowest costs.

13. 13 LCA/Econ Analysis  Project Objectives –Conduct LCA on organics diversion alternatives –Complete economic analysis for recycling and organics diversion alternatives  Project Outcomes –Customized GHG tool GHG emissions Diversion Cost Regional scenarios

14. 14 Workshop Agenda  Presentations on background, technical information and perspectives. –Morning Session 2 – Technical Information Landfill Gas Primer – Scott Walker, CIWMB Inventory – Byard Mosher, CARB Climate Registry – Rachel Tornek, CCAR LF Emission Estimates – Guido Franco, CEC LF Management Practices – Pat Sullivan, SCS Engineering  Discussion of “Measures” that can help CIWMB meet GHG emission reduction strategies.
