Title: Precautionary Principle From Vision Statement to Practical Policy
1 Precautionary Principle From Vision
Statement to Practical Policy
- Jared Blumenfeld Debbie Raphael
- www.sfenvironment.org
- (415) 355-3700
2The Goal Transforming the way we make decisions
- Instead of asking, "How much environmental harm
will be allowed?, in San Francisco,
decision-makers will ask a very different
question "How little harm is possible?"
3What Got San Franciscos Attention?
- Local Community Interest
- Bay Area Working Group on the Precautionary
Principle - Breast Cancer Fund
- Commonweal
- Center for Environmental Health
- Mayor
- Commission on the Environment
- Department of the Environment
4The Public Process
- Direction from elected officials
-
- 18 months of public meetings
- Input from business groups
- Committee on Jobs
- Chamber of Commerce
- Labor Unions
- American Chemistry Council
- Consultation with subject matter experts
5Precautionary Principle and Risk
- We acknowledge that our world will never be free
from risk. However, a risk that is unnecessary,
and not freely chosen, is never acceptable.
6Precautionary Principle and Science
- San Francisco's Precautionary Principle insists
that environmental decision-making be based on
rigorous science -- science that is explicit
about what is known, what is not known and what
may never be known about potential hazards.
7The Precautionary ApproachRisk vs. Alternatives
Assessments
- Alternatives Assess.
- Is this potentially hazardous activity (product)
necessary? - What less hazardous options are available?
- How little damage is possible?
- Risk Assessment
- What is an acceptable level of harm? (i.e. of
cancers in 1000 people) - Does this activity (product) fall within that
acceptable level?
8The alternatives assessment is also a public
process because, locally or internationally, the
public bears the ecological and health
consequences of environmental decisions.
9The Precautionary Principle does not determine
the outcome, it creates a process.
10Five Tenets of SF Ordinance
- 1. Duty to take anticipatory action to prevent
harm - Historically, environmentally harmful activities
have only been stopped after they have manifested
extreme environmental degradation or exposed
people to harm. -
11Waiting Too Long?
- Lead in gasoline, paint
- Asbestos in building materials
- Tobacco
- PCBs, DDT, CFCs
- PVC, Brominated Flame Retardants
- Global Warming
12Five Tenets of SF Ordinance
- 2. Right to know complete and accurate
information burden to supply this information
lies with the proponent not the general public - Potential human health and environmental impacts
are often not disclosed or even known - Examples Inerts in pesticides Only 10 of
some 80,000 chemicals in commerce have full range
of health effects data
13Five Tenets of SF Ordinance
- 3. Duty to examine a full range of alternatives,
including doing nothing - Obligation to select alternative with least
potential negative impact - Selecting which alternative is preferable is a
political/public decision - Examples Least toxic cleaning products
Alternatives to pesticides Increase in bike
paths -
14Five Tenets of SF Ordinance
- 4. Must consider the full range of costs,
including costs outside the initial price - All reasonable foreseeable costs such as raw
materials, transportation, manufacturing, clean
up, disposal - Examples Green Buildings Power generation
15Five Tenets of SF Ordinance
- 5. Decisions must be transparent, participatory,
and informed by the best available information - A government's course of action is necessarily
enriched by broadly based public participation. - This concept of environmental democracy is
deeply ingrained in San Francisco's Precautionary
Principle.
16Implementation
- Arsenic Treated Wood
- Evaluated health and environmental impacts
- Sufficient evidence of harm
- Alternatives analysis revealed
- Most applications have a less toxic formulation
(ACQ, CBA) - Submerged Aquatic applications - arsenic treated
wood is the most environmentally preferable
formulation
17SF Implementation
- Regulations
- Integrated Pest Management
- Arsenic-treated wood
- Purchasing
- Green Building
- New Avenues for Discussion
- Recycled Water
- Power Plant Development
- Links to Environmental Justice
- Land Use/Zoning Decisions
- More possibilities.
18The Precautionary Principle
- ? Zero risk
- ? Zero science
- ?Predetermined outcome
- (i.e. ban)
- Minimize harm
- Maximize information/science
- Process for public decision making
19Re-defining the Central Question for Decision
Makers
- It is NOT sufficient to ask
- Is it legal?
- Is it safe?
- We Also MUST ask
- Is it necessary?
