1. System Condition 2 Efficient use Inefficient use
Dissipative use
Persistent and Unnatural
Abundant and breakdown easily
Tight Technical Cycles
Inefficient use
Efficient use
We cannot emit more waste products than nature can process.
Two parts to the problem:
a) We are producing substances that are alien to nature
b) We are producing substances familiar to nature at a rate faster than it can cope with, leading to accumulation
Society produces over 70,000 synthetic chemical compounds commercially, many of them persistent as they cannot easily be metabolized by the biosphere.
Examples include DDT, PCBs, CFCs, endocrine disrupters leaching from plastics (gender benders!)

2. System Condition 3 Inefficient use of resources and land
Resources from poorly managed ecosystems
Resources from well-managed ecosystems use
Efficient use of resources and land
We must not systematically undermine the ability of nature to “pay the bills”, as photosynthesis is the only large scale net producer of order on Earth.
We must also maintain its productive capacity.
Currently we are experiencing worldwide deforestation, soil erosion, increased salinity of soils, infertility of soils, depletion of fisheries, and loss of biodiversity.

3. System Condition 4 - Unsafe working and living environments
In order to be able to achieve the first three system conditions, society must also be sustainable.
We must meet human needs worldwide.
Inefficiency works like a gas pedal on the other three system conditions
Sufficient resources for livelihood
Economic barriers
Political oppression and violations of human rights
Political freedom and respect for human rights

4. FUNDAMENTAL HUMAN NEEDS
Protection
Affection
Subsistence
Understanding
FUNDAMENTAL HUMAN NEEDS
Freedom
Participation
Identity
Idleness
Creation

5. What is Whistler2020? Vision and strategic plan Comprehensive
Long-term
Community-wide
Highest level policy
Whistler2020:
Addresses both the WHAT (vision, priorities) and the HOW (strategies
Comprehensive: addressing ALL aspects of community success and sustainability
Long-term: taking a 15-year time horizon in the context of achieving sustainability by One step in the journey.
Community-wide: developed and implemented by the entire resort community NOT just a municipal plan
Systems and science-based: ONLY plan in north America that uses the science-based TNS framework at all levels of planning and decision making
Highest level policy: rewriting OCP

6. How is it integrated? Our approach (Backcasting from principles)
Brief e-learning excerpt (live)
Into funnel metaphor
Into a backcasting from funnel
Introduce the constraints (TNS system conditions)
Strengths of this approach
Demonstrate the manner by which this central theory is applied
Capital budget assessments
CEGs, Sustainable purchasing approach etc…
SHARED LANGUAGE - IMPORTANCE

7. Benefits of Principles
Shared language, understanding and ownership
Useful at all scales and levels, for planning and decision making
Proactive and upstream, address root causes, pressures
Integration across all elements of community life, business processes
Non-prescriptive, measures what’s needed, encouraging creativity and unique visions and solutions
Benefits of backcasting more obvious, but from principles and in particular these principles the benefits are
