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.

Carbon dioxide (CO2) 1Methane (CH4) 23Nitrous oxide (N2O) 296Hydroflurocarbons (HFCs) 120-12,000Carbon tetrafluoride (CF4) 5,700Hexafluorothane (C2F6) 11,900Perfluorobutane (C4F10)8,600Perfluorohexane (C6F14)9,000Sulfur hexafluoride (SF6) 22,200

Climate Change StrategiesAchieve 50% Statewide Recycling

Reduce GHG emissions associated with energy-intensive material extraction and production by increasing recovery of recyclables.

Zero Waste / High RecyclingIncrease recovery of recyclable materials from landfills

and create marketable products from organic materials.

Landfill Methane CaptureCapture methane from landfills via gas recovery systems.

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

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

LCA/Econ AnalysisProject 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
