The Rich, the Poor, and Their Contribution to Un-
sustainable Consumption.- Agenda 21, in Chapter Four
(United Nations Conference on Environmental Develo-
pment 1992) addresses unsustainable production and
consumption patterns, and links poverty to environmen-
tal degradation; however, it also mentions the dierent
elements that drive consumption to unsustainable situa-
tions, in which consumers demand more resources than
their local environment has the capacity to provide and
regenerate (Shiva & Emmott 2000). Agenda 21, Chapter
Four has three main objectives. The rst two objectives
are related to eciency in production and consumption
processes, and make reference to action through public
policy. Only the third objective relates to the reinforce-
ment of values, which is this paper’s focus. This third
objective states the importance of transferring environ-
mental technologies to developing countries. We do not
emphasize the technological aspects of sustainability
here, because it goes beyond the position of transferring
technologies to developing countries, as stated at the end
of the third objective of Agenda 21, Chapter Four. The
Agenda 21 position may sound somewhat arrogant when
not accompanied by a mea culpa from the countries that
create a larger footprint as a result of their unsustainable
consumer behavior. It is dicult to state at what point
consumption becomes unsustainable. One approach
could be to consider the moment at which the resources
needed to produce goods or services reach a point when
they can no longer regenerate. One tool for assessing
the impact caused by a product or service is Life Cycle
Analysis (LCA); (ISO 2018). LCA measures the crad-
le-to-grave impact in terms of outputs and inputs, energy
use, and raw materials. It also examines the impact the
product or process has on the environment and human
health. LCA should be used as a wake-up call and as a
source of information for policy makers, industries and
consumers in general to make informed decisions prior
to determining which product or process to choose.
Agenda 21, Chapter Four claims that poverty causes
stress on the environment, but it clearly concludes that
the main global causes of environmental degradation
and unbalance are unsustainable consumption patterns
in developed countries (United Nations Conference on
Environmental Development 1992; SD21 2012). This
unbalance is caused not only by environmental and eco-
nomic factors, such as the depletion of natural resour-
ces, but it is also embedded in the social sphere. It is
perceived that wealthier consumers have more access to
natural resources due to their greater economic capacity,
and consequently place more pressure on resources than
the poor. However, it is important to consider the die-
rent elements that can be used to characterize consumer
behavior, such as age, biases, access to information, at-
titude, gender, local environmental awareness, cultural
and educational background, knowledge, peer inuence,
season, and, of course, the emotive aspects of consumers
and income (OECD 2008; UNEP 2010). One thing that
strongly drives consumer choices, however, is perso-
nal values (Auty & Elliot 2002; UNESCO 2010; Nor-
berg-Hodge 2011). Mirzaei and Ruzdar (2010) state that
consumer behavior is a mental, physical and emotional
process that operates before, during and after the purcha-
se. They establish that purchasing decisions for buying
cars, for example in Iran, are more related to a social
dimension, as well as to income and education. They hi-
ghlight three social factors that inuence car purchases:
reference groups, social status, and family; however, in
their study, social status and family inuence were the
most important factors. Social status is described as the
respect that society pays to the role of an individual or
a group. That respect is associated with the society’s ex-
pectations, which operates as the trigger for acquiring a
particular item or service. The family is also described
by Mirzaei and Ruzdar (2010) as the rst reference group
for a consumer’s decision-making process. The family is
perceived as the primary purchasing unit, which varies
according to the nature of the family.
In a larger context, consumers from developed countries
demand resources beyond the carrying capacity of their
own ecosystems.This demand is consistent with the
tendency of liberalizing global trade, which promotes
exports from poor areas. As a result, cash crops
oriented towards global commerce compete against
the production of staple foods for local consumption,
creating scarcity, lower self-reliance, and more poverty,
especially in developing countries (Shiva and Emmott
2000; Shiva 2002; Norberg-Hodge 2011). The conict
between desires and needs has produced a distortion in
many consumers’ consumption patterns, mainly because
consumption capacity seems to be an indicator of
achievement in contemporary societies, especially in the
so-called Western World. A 2012 report from Sustainable
Development (SD21 2012) notes that North Americans
consume around 90kg of resources per day, compared
to 10 kg for consumers in Africa. This example helps
to illustrate the massive inequality and discomfort that
these extravagant consumption patterns, by becoming
socially accepted in the wealthier countries, can create in
other parts of the world (Burgess 2003; Norberg-Hodge
2011). It is widely acknowledged that consumption
helps economic growth, and hence it is encouraged by
governments and mainstream media as an indicator of a
healthy economy. The assessment of the achievements
of Agenda 21 in terms of sustainable consumption
are embarrassingly poor. The growth of the planet’s
