2 Overarching Points
Upstream processes create 71 times
more impact than what ends up in cities
Comprehensive Zero Waste in our cities
can dramatically reduce GHG
Zero WasteGAIA
Tip of the “Wasteberg” Impact
Municipal
waste
tip of the
“wasteberg”Upstream waste produced is 70
times greater than at municipal level
Zero WasteGAIA
Climate Change and Waste Diversion
Reduces energy &
emissions upstream
Reduces methane
emissions from landfills
Increases storage of carbon
in soil & biomass
Decreases use of petroleum-
based fertilizers and pesticides,
and reduces water use

Unique San Francisco Aspects:
Each city has its own
The same company,
Recology, has exclusive
right to haul refuse for
over 80 years
Pay As You Throw
(PAYT) has been in
place for almost 90
years
Zero WasteGAIA
History Matters: Same local hauler for over 80 years –
Recology Waste Zero
Zero WasteGAIA
Pay for Waste like you do for a
Utility, like electricity, water,
gas
The more they use, the more
they pay
Allows incentives for recycling,
composting and reuse
Provides a dedicated funding
stream for our programs
Customers:

In 2002 we projected Zero
Waste programs to reduce
302,000 tons/year of the 2,500,000 ton goal by 2012
We believe the Zero
Waste reduction will be
significantly greater
