Case Study |
It has been widely suggested that patterns of consumption exhibited by
end consumers such as individuals and small institutions may be the
fundamental engine driving environmental degradation. I will discuss
this assertion, and then investigate price and non-price methods for
encouraging rational consumer decisions that can achieve measurable,
sustainable reductions in the destructive characteristics of that
consumption at an appropriate scale.
The principle of consumer sovereignty, according to Stiglitz, holds that
...individuals are the best judges of what is in their own interests
and that their preferences should be respected. Gottheil (7) states
that this right to choose what we want dictates what producers will
ultimately produce, just as our right to choose our political leaders
dictates what kind of government policies we ultimately get.
But what information do consumers use in making their choices? Need and
availability are key factors, certainly. Price is another. The classic
cost-benefit analysis, which takes place either explicitly or
unconsciously before every market transaction, balances need (or desire)
as measured in terms of marginal utility or benefit, against price. Put
simply, the consumer is asking, Is it worth the cost?
An individual, rational, and reasonably well-informed economic actor,
having learned through exposure to various communications media that
dirty air, contaminated water, and resource-driven global conflict
persist and may indeed be attributed to functions of economic systems,
might be motivated to examine and ameliorate his or her own role in
relation to those economic externalities if the prospect of some
meaningful outcome exists. I will suggest that this actor may not be
inexorably constrained either by first principles of self-interest and
price mechanisms or, at the other extreme, by nonspecific, shifting
social values expressed as exhortations to voluntarily conserve,
recycle, preserve, and
There is no environmental impact statement required of the individual or
small-scale economic actor. When corporations experience political or
market pressures as a result of pollution events they attempt to
exculpate themselves by blaming consumers, because in the simplest
paradigm of an economic system it is the end consumer who creates
demand, which in turn drives production. When environmental
catastrophes occur, such as the Exxon Valdez oil spill of 1989, even
environmental groups remind individual consumers that they are
ultimately to blame, as when Greenpeace ran full page advertisements in
key newspapers around the world showing a photograph of Exxon Valdez
Captain Joseph Hazelwood, and beneath it the caption: It wasnt his
driving that caused the Alaskan oil spill. It was yours.
If individual consumption patterns possess embedded destructive
characteristics, and if consumer behavior is a significant influence
upon the worlds environmental problems, then it follows that there
should be small-scale impact assessment resources that have emerged,
perhaps unnoticed, from the body of research studying consumer behavior
and the environmental perspective.
The Clearwater Carbon Calculator© has been developed after an exhaustive
search and thorough examination of potential resources. I am suggesting
that awareness of quantitatively-expressed specific environmental
impacts at local scales may be able to empower and enable aggressive
local (individual, household, small institution, bioregion) responses to
that impact. In my opinion the Clearwater Carbon Calculator© offers an
antidote to the helplessness and sense of futility that all-too-often
pervades the discourse of environmentalism.
Environmental degradation caused by non-sustainable patterns of human
production and consumption has been amply documented. What concerns us
here is the fact that despite decades of supply-side approaches to
controlling or reversing this degradation, the air is still polluted and
becoming increasingly so, water is still polluted, open space is rapidly
disappearing, and even global systems such as ocean currents and
atmospheric climate may be uncontrollably altered. Measuring
environmental degradation is a piecemeal affair, taking place at all
different scales and using every conceivable metric, from the number of
spots on invertebrate worms in a local stream to the tons of an
indicator pollutant being emitted by smelter smokestacks on a continent.
It would be a gross oversimplification to state baldly that
environmental degradation and economic activity are causally related,
but certain economic transactions do unquestionably result in effects
that impede the normal functions of environmental systems (e.g. electric
power generation and acid deposition), and further, in trends that
society deems to be undesirable (e.g. loss of open space to look-alike
housing developments). Hence it may be useful to link environmental
impact analysis with economic structures. Looking at the history of
environmental concern in the western world, we find that society has
overwhelmingly chosen to control environmental degradation by
controlling events occurring at the supplyproducerside of the
economic transaction.
Largely overlooked has been the demandconsumerside of the economic
transaction. Certain controls aimed at slowing or halting the purchase
of environmentally harmful goods or services have been implemented, such
as the ban on sales of leaded gasoline or paint, but the net burden has
fallen on the suppliers, and consumers were given no choice in the
matter. In the case of lead this ban has conveyed a strong public
benefit to consumers in the form of improved health, particularly among
children. But a similar control, the imposition of oxygenated gasoline
containing the additive methyl tertiary butyl ether (MTBE), has resulted
in widespread groundwater contamination and health problems that have
far outweighed the potential benefits. Consumers had no choice with
regard to either lead or MTBE, but the range of outcomes swung wildly
from strong success to unmitigated failure.
Without intimating that consumer choice might have brought about a
better outcome in either case, I suggest that the market for the public
good a healthy environment may be functioning poorly, despite
command-and-control supply-side controls, because the high-quality
information needed for a market to perform efficiently is severely
constrained or altogether missing. The Clearwater Carbon Calculator©
offers a simple method with which consumers can voluntarily measure
their own contribution to a degraded environment, and a framework in
which they can make rational choices regarding the environmental
component of information involved in their transactions.
Hopefully, the outcome of this exercise will be a more efficient market
for the public good a healthy environment, when measured at the
individual, household, or small-institution scales.
In basic microeconomic theory, everything the consumer needs to know is
supposed to be embodied in the price of a good or service. In their
discussion of the assumptions underlying perfect competition, Browning
and Browning say, for consumers the relevant information is a
knowledge of their own preferences and the prices of the various goods
and services of interest to them. In fact, all the details of research
and development, the lengthy and risky start-up process, the interest
rates on the companys various loans and bonds, the costs of materials,
complex labor transactions, shipping at many levels, advertising,
storage, the thousands of discussions, calls, and e-mails that may have
gone into production of a T-shirt in Sri Lanka and its subsequent
arrival at the holiday open-air market on Union Square are buried in a
single, simple numberthe price. It seems almost sacrilegious to
suggest that prices dont tell the whole story because they tell so
much. But, quoting Stiglitz again:
Some kinds of information, like information about the weather, are
public goods: the marginal cost of an additional individual benefiting
from the information is negligible, and the cost of excluding
individuals from this information may be considerable. This kind of
information can also be important for efficient functioning of the
economy, but markets do not produce efficient amounts of it.
Stiglitz goes on to say that weather information is therefore supplied
by the government, as a classic example of instances where government
steps in to maintain economic efficiency in imperfect markets. But who
is stepping in to tell us about the quality of life among the people
sewing the T-shirt in Sri Lanka? Who is looking at the pesticides being
applied to the cotton fields, and to the health impacts upon pesticide
factory workers, farm workers, and farm neighbors? Who is telling us
about the excessive demands for water upon the cotton fields, water
which could be used to irrigate many more acres of arable land in food
production? From where do we learn about the gradual, irrecoverable
salinization of irrigated fields? Who is telling us about the impact on
American workers from having the shirts manufactured overseas, and who
can tell us about the particulates, oxides of nitrogen and sulfur, and
carbon emissions from transport?
To the extent that these elements of a goods life cycle involve costs,
they are accounted for in the price, without question or judgment. But
some economistsClifford Cobb, Ted Halstead, Jeff Hammondwould say
that in conventional markets any transaction is a good transaction,
whether it be a blood transfusion to an AIDS patient or the funeral of a
soldier brought back from a war in the Middle East, where access to
precious oil reserves is at risk.
Hence, it is not enough to simply account for costs in the price of a
good, and expect an efficient outcome.
Prices do not include information about externalitiestransactions
that have escaped the accounting process throughout the goods life
cycle. Externalities include emissions of carbon to the atmosphere,
particulates to the lungs of a black teenager in Hunts Point, pesticide
runoff into rivers and their subsequent uptake by gamefish at the top of
the food web, and social costs that arise from inhalation or ingestion
of pollutants. Prices include the costs of process feedstocks, such as
the PCBs that washed into the Hudson River for over twenty-five years
from two GE plants near Glens Falls, but not the costs of recovery,
cleanup, analysis, or the impacts of contaminated fish ingestion upon
immigrants and communities of color: reduced intelligence, behavioral
abnormalities, and cancer (although prices may be adjusted after the
fact to include those expenses after the company is forced to undertake
a cleanup). Prices include the costs of fuel oil for ships, trucks, and
airplanes, but cannot address the threat of flooding in Bangladesh or
Bimini that may ensue if Antarctic ice continues to melt. Prices do
include the entiretyand many suspect that it is the entirety plus
interestof firms transaction costs with government over
environmental regulation.
The information buried within prices is not retrievable and is tightly
bundled with all the other bits of matter. Price information is,
therefore, a summary accounting, but not a detailed disclosure. In this
document I suggest that prices, while remarkably effective conveyors of
relevant transaction-related information, fall short of informing
consumers about many or all of the environmental consequences of their
transactions.
Global warming, as a current environmental issue, is the result of an
anthropogenically-induced imbalance in atmospheric composition leading
to increased heat absorption as solar radiation passes through the
earths atmosphere. Fossil-fuel combustion, deforestation, agriculture,
and use of chemical refrigerants are the principal contributors to
accelerated heat absorption. These activities generate emissions of
carbon dioxide, nitrous oxide, methane, and chlorofluorocarbons (CFCs)
the most notable greenhouse gases.
Researchers point out that anthropogenic global warming probably will
induce an array of uncontrollable natural greenhouse gas emissions.
Most notable among these is the probability, already supported by
depth-to-permafrost data, that melting Arctic tundra will generate vast
releases of methane, a greenhouse gas more potent than carbon dioxide by
a factor of 63.
Atmospheric carbon dioxide has been measured since 1958 at a monitoring
station on Mauna Loa, Hawaii. In 1958, readings varied in a seasonal
range from 315-318 parts-per-million (ppm). As of 1990, levels were
exceeding 350 ppm, an increase greater than 10 percent in 32 years.
Perhaps more alarming, while fossil fuel-attributable CO2 began do
exhibit a slowing growth slope following the price hikes of the early
1970s, and the onset of environmental regulations in parts of the
world, atmospheric CO2 continued to increase unimpeded, evidence of
poorly-understood positive feedback variables, such as continued
deforestation (23% of CO2 inputs) and methane releases from melting
tundra (ibid).
Overwhelmingly, it is carbon dioxide that has become the target of the
IPCC and the international community of NGOs working on global warming.
Deforestation and fossil fuel consumption remain the most intractable
and ubiquitous contributors to increasing concentrations of atmospheric
greenhouse gases.
As the policy paralysis of the past decade clearly indicates,
international and governmental initiatives may not be sufficient to
reduce anthropogenic carbon dioxide emissions enough, or in time, to
avert serious, destabilizing global climate-related effects by the
middle of the next century. The Kyoto Accords, for example, have not
yet been ratified by most member nations, and while they establish a
trading mechanism designed to reduce carbon emissions from large-scale
point sources, there are no enforcement mechanisms in place or on the
horizon.
Therefore, the source for emissions reductions with the most near-term
potential may be the small-scale emitters; the individuals, households,
and smaller institutions among the developed nationsthe most prolific
producers of atmospheric carbon. These small-scale emitters require
data regarding their carbon emissions, and a mechanism for monitoring
and managing reduction. Toward that end, in the Spring of 1992, an ad
hoc group of researchers at the Woods Hole Research Center undertook a
study or their institutions direct and embodied carbon emissions.
Though unpublished, their report formed the starting point for the
Clearwater Carbon Calculator©, and my readings in Ecological Footprint
Analysis led to the use of a programmed spreadsheet as the most
effective tool for delivery of a carbon audit tool.
