Issues to Consider:
- Problem (from Garett Hardin (1968) The Tragedy
of the Commons: "Picture a
pasture open to all (!!). It is to be expected that each herdsman will
try to keep as many cattle as possible on the commons... Explicitly or
implicitly, more or less consciously, he asks,
"What is the utility to me of adding one more animal
to my herd?"
- Economic: (My) marginal benefit / (my) marginal cost.
- Benefit is all mine, but the cost is distributed over all
--> negative externality.
- Individual
interest ≠ community interest.
- Short-term interest ≠ long-term interest; interests
cannot be 'sustained.
- Overall result:
'common' resource disappears and the disappearance accelerates.
- Problem: can you think of (other)
real-world
examples of this? What about other, nonenvironmental common
resources?
- Maximally sustained grazing yield
of
the commons.
- Maximally sustained fishing
harvests.
- Maximally sustained throughput of
cars at 55M/Hr. on a highway.
- Problem: Do you know of other,
nonenvironmental or business systems that have carrying capacity?
- Web servers: denial of service
attack.
- Tragedy of the commons: rational
(short-term, individual) behavior leads to rapid exceeding of a common
(public) system's carrying capacity, harming the individual in the long
run.
- Problem: How
could we measure the impact of our business on the 'commons? Can we
compute the marginal benefit / marginal cost?
- Improperly disposed used oil US/year: 200M gallons (20
× Exxon Valdez).
- Delta Airlines (2003): 2.37B gallons of fuel.
- Encyclopedia
of Earth:
- US manufacturing electricity inputs: 3,102 TBTU vs. 6,444 TBTU losses:
- Switching off the light saves (the commons) three
times as much as it uses.
- 95% of the power consumed by an incandescent light
bulb is converted into heat ==> go figure...
- Of 24,658 TBTU footprint, only 10,699 TBTU(43%) is used
for
actual processing (not counting processing losses).
- Carbon: BP
Carbon (CO2) calculator.
- Land.
- Etc.
- Sustainability in business: triple bottom line:
- Financial sustainability.
- Environmental sustainability.
- Social sustainability:
- Ways to escape the Tragedy of the Commons: Privatization --
Government Control -- Hybrid solutions:
- When does an environmentally friendly process or product change
reduce cost?
- When the environmental resource(s) is a commodity
rather than
a commons.
- When not making that change leads to (costly) legal action.
- Two ideal-typical ways of escaping the Tragedy of the Commons:
- privatization ==> commodification ==> trade.
- government control ==> taxation (quasi commodification)
and legal constraints.
- Hybrid: government sets (legal) constraints or boundaries but
allows markets
to flexibly meet these constraints; e.g.,
carbon
(emission) trading.
- Metters et al.: environmentally friendly measures often
help the
financial bottom line:
- Delta Airlines' single-engine taxiing (environmental
friendliness as a
byproduct).
- Royal Dutch Shell selling its CO2 to carbonate soft
drinks.
- UPS redesigning its packaging making it lighter.
- Home Depot offering certified lumber products.
- Process redesign:
- Rackspace
Managed Hosting (San Antonio, TX) got its computer hardware vendor
to stop including redundant cables, manuals, spare parts, etc.
with its orders (or bundle them in a single package).
- Reverse logistics (aka reverse supply chain): Radio
Frequency IDentification (RFID).
- Dematerialization: replacement of material (physical) goods
and people-based (wetware)
activities with immaterial ones:
- Shrinking the world through information systems ==>
cutting on transport:
- Personal: calling the store and ask if the item is in
stock rather than driving out to go check.
- Replacing paper with electronics for storing information.
- Mitchell, R.L. FAQ About Going Green
(ComputerWorld, Sep.
3, 2007):
- "The cost of electricity over a three-year period now
exceeds the acquisition cost of most servers."
- "The biggest savings come from server consolidation
using virtualization technology."
- Metters et al. p. 65: DuPont automobile painting
street:
- Note: process remains virtually intact; dematerialization
caused by change of ownership!
- Problem: Think of
examples where companies initiate environmentally friendly measures.
Why do they do this? Does it lower their cost? Improve their products?
Improve their processes? Improve their image? Do they just want to do
good? Any other reasons you can think of?
- Winco Foods
(Corvallis): Paper
or plastic? 5ct. discount for every paper grocery bag
that you use again at checkout.
- Coffee places that give you a small discount if you bring your
own cup.
- Problem: Try to think of all the
advantages and disadvantages for businesses of being sustainability
sensitive.
- Problem: What are the advantages or
disadvantages of each of the three methods to overcome the Tragedy of
the Commons: privatization, government control and hybrid solutions?
