What are
Greenhouse Gases (GHGs)?
4
Past & Future CO2 Atmospheric
Concentrations
5
Consequences of a Warmer Planet
  • Sea level rise
  • Spread of certain diseases out of their usual geographic range
  • Effects on:
    •  agricultural production,
    • water supply,
    • ecosystems,
    • increased strength and frequency of storms,
    • extreme heat events, and
    • air pollution episodes
6
Potential impacts of these effects on human health and the economy.
7
Executive Order Established Statewide GHG Targets
8
Assembly Bill 32

    • Establish a statewide greenhouse gas emissions cap for 2020, based on 1990 emissions by January 1,
    • 2008.
    • Adopt mandatory reporting rules for significant sources of greenhouse gases by January 1, 2009.
    • Adopt a plan by January 1, 2009 indicating how emission reductions will be achieved from significant
    • greenhouse gas sources via regulations, market mechanisms and other actions.
    • Adopt regulations by January 1, 2011 to achieve the maximum technologically feasible and cost-effective reductions in greenhouse gas, including provisions for using both market mechanisms and alternative compliance mechanisms.

Climate Change Strategies
  • Achieve 50% Statewide Recycling
  • Reduce climate change emissions associated with energy-intensive material extraction and production, as well as methane emissions from landfills.
  • Zero Waste / High recycling
  • Measures that result in additional recovery of recyclable materials from landfills and transforming organic/biomass and plastic waste into marketable products are being considered.
  • Landfill Methane Capture
  • Capture of methane emitted from landfills via a gas recovery system.


10
Climate Benefits
  • 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

Life-Cycle Approach

13
Energy Benefits
  • Decrease the Demand for Raw Materials (e.g., trees, bauxite)
    • Reduce energy associated with raw material extraction
  • Reduce the Amount of Energy Needed for Manufacturing and Transportation
  • Energy Production from Landfill Gas & WTE

Recycling Energy Savings

15
The Connection:
Waste Management & GHGs
  • Energy Consumption
    • fossil fuel combusted to make, transport, use, process, and dispose of products
  • Methane (CH4) Emissions
    • from landfills
  • Carbon Sequestration
    • Deforestation reduces atmospheric carbon storage
    • Conserving trees removes carbon from the atmosphere and stores it for long periods or permanently

Organics Focus at CIWMB
  • Look at organic materials management from a LCA approach
  • See array of options and what they will mean for maximizing GHG reduction while increasing diversion at the lowest costs.
