Natural resources
Our lives depend on the availability of essential
natural resources. Increasingly, these are coming under pressure. From a
human viewpoint, natural resources can be characterized as:
- the resources we consume - such as energy, water, soil, and food;
- those needed by the planet to absorb and neutralize the waste materials we
generate - from carbon dioxide and other gases to
solid and liquid wastes. These include water (in rivers, lakes and
coastal habitats.
It is the depletion of these resources in particular which is causing growing
concern. These, along with a diverse mix of
species, a stable atmosphere
and
ozone layer, are sometimes called 'critical' resources.
This reflects the fact that they are crucial to the planet's health, and cannot
be replaced by human invention. All are to some extent being disrupted by human
activity. The consequences are uncertain, but could potentially be disastrous.
Resources are often referred to as
renewable
(soil, water, fisheries, forests, energy from solar, wind, water power or fuel
crops) or
non-renewable
(minerals such as coal and oil).
Sustainable development
Sustainable development (SD) is a pattern of resource use, that aims to
meet human needs while preserving the environment so that these needs can
be met not only in the present, but also for generations to come (sometimes
taught as ELF
-
Environment, Local people, Future). The term was used by the Brundtland
Commission which coined what has become the most often-quoted definition of
sustainable development as development that "meets the needs of the present
without compromising the ability of future generations to meet their own needs."
Sustainable development ties together concern for the carrying
capacity of natural systems with the social challenges facing humanity.
As early as the 1970s "sustainability" was employed to describe an economy "in
equilibrium
with basic ecological support systems." Ecologists have pointed to The Limits to
Growth, and presented the alternative of a "steady state economy"
in order to address environmental concerns.
The field of sustainable development can be conceptually broken into
three constituent parts: environmental sustainability, economic sustainability
and
sociopolitical sustainability.
The business case for sustainable development
The most broadly accepted criterion for corporate sustainability constitutes a
firm’s efficient use of natural capital. This eco-efficiency is usually
calculated as the economic value added by a firm in relation to its aggregated
ecological impact. This idea has been popularised by the World Business
Council for Sustainable Development under the following definition:
"Eco-efficiency is achieved by the delivery of competitively priced goods and
services that satisfy human needs and bring quality of life, while progressively
reducing ecological impacts and resource intensity throughout the life-cycle to
a level at least in line with the earth’s carrying capacity." Similar to the
eco-efficiency concept but so far less explored is the second criterion
for corporate sustainability. Socio-efficiency describes the relation between a
firm's value added and its social impact. Whereas, it can be assumed that most
corporate impacts on the environment are negative (apart from rare exceptions
such as the planting of trees) this is not true for social impacts. These can be
either positive (e.g. corporate giving, creation of employment) or negative
(e.g. work accidents, mobbing of employees, human rights abuses). Depending on
the type of impact socio-efficiency thus either tries to minimize negative
social impacts (i.e. accidents per value added) or maximise positive social
impacts (i.e. donations per value added) in relation to the value added.
Both eco-efficiency and socio-efficiency are concerned primarily with increasing
economic sustainability. In this process they instrumentalize both natural and
social capital aiming to benefit from win-win situations. However, the business
case alone will not be sufficient to realise sustainable development. They point
towards eco-effectiveness, socio-effectiveness, sufficiency, and eco-equity as
four criteria that need to be met if sustainable development is to be reached.
