Concept evolving for over 40
years since the 1972 UN
Conference on the Human
Environment (Stockholm)
Since it gained
prominence, its
definition and
description has varied
Gained recognition alongside other related
issues e.g. conservation, ecosystem
services and social concerns
Has to evolve and be
adapted to the real world:
for all sectors including
finance, investors,
economists and traders
SD Projects need to be:
1) Economically and Financially Viable
2) Environmentally Sound
3) Take into account Social Issues
4) Governed & Supported Appropriately
National Income redefined as: "sustainable social net product" (Sir John Hicks)
Savings, as a % of GDP, should be greater to or equal to the sum of
the depreciation of human knowledge plus the depreciation of
human-made capital plus the depreciation of natural capital
Strong sustinability requires EACH to increase or remain constant over time,
Weak just requires SUM to increase or remain constant
Originated with quantities such as
MSY - working at the maximums -
but this is not necessarily
sustainable in the long term
1987: World Commission on Environment and
Development, chaired by the Prime Minister of Norway:
Gro Harlem Brundtland, report: "Our Common Future"
or the Brundtland Report
landmark document
creating separately existing
environmental institutions is not enough
because env issues are an integral part
of all development policies
Env issues are crucial to economic
consideration as part of energy decisions,
social issues and development work
"Sustained human progress not just in a few
places for a few years, but for the entire
planet into the distant future"
1992 UN Conference of Environment and
Development, Rio de Janeiro - The Earth Summit:
Endorsed "Agenda 21" a "Think piece"
and program of action governing human
activities with impact on the
environment
2002 Wold Summit on
Sustainable
Development, heads of
state and world
leaders committed to
implement Agenda 21
Finalised the UN Climate Change Convention and Biodiversity
Convention, signed my many heads of states
responsible for the ratification of the Kyoto Protocol
It's Clean Development Mechanism: designed
in part to assist participating developing
countries in achieving sustainable
development
Brundtland Report 1987: development that meets the needs of
the present without compromising the ability of future
generations to meet their own needs
Reppetto, R. 1986 "the core idea of sustainability is that current
decisions should not impair the prospects for maintaining or
improving future living standards. This implies that our economic
systems should be managed so that we can live off the dividends of
our reourses"
Daly, H.E. 1987 "increase in moral
knowledge or ethical capital for mankind"
Munasinghe, M. 1993: 3 approaches to SD - the triple bottom line
1) economic - maximising income while maintaining a constant or increasing stock of capital
2) ecological - maintaining resilience and robustness of biological and physical systems
3) social-cultural - maintaining stability of social and cultural systems
used to gauge success of projects

Achievability
Measuring Environmental
Quality (Rogers and Jalal et al.
1997): "9 ways to achieve
sustainability"
1) Leave/Return everything
in a pristine state
2) Develop without overwhelming the
carrying capacity of the system
what is the globes carrying capacity?
If it is exceeded - what next?
3) Sustainability will take care of itself as
economic growth proceeds: Kuznets Curve
continuously degrading system
with development of populations
4) Polluter and victim can arrive
at an efficient solution
themselves (Coase)
Can work well on a small
scale - national or global?
Transaction costs high
5) Let the markets take care of
it - the invisible hand
Prices on pollution and permits on pollution trading
6) Internalise the Externalities
How to value and quantify
externalities for economic analysis?
7) National economic accounting systems
should reflect defensive expenditures -
accounting should consider resources
GDP is benefited by pollution
and resource use: indicates
expenditures
8) Reinvest rents for non renewable
resources - strong and weak
sustainability
large oil companies are
investing profits into
renewable technologies
9) Leave future generations the options or
the capacity to be as well off as we are
Can we continue to
progress and improve?
How do we ensure it?
Life - Cycle Analysis
can prove the sustainability of small lifestyle choices
look at raw materials, production and disposal (potential heat recovery) / reusability
Environmental impacts: pollution, emissions, raw materials, utilities e.g. electricity
imperative to achieve SD to consider environmental
concerns, new legal requirement, economic and social costs
Considerations
population growth, consumption, production, pollution, effects of legal
requirements, poverty, international law and environmental agreements
poverty, population, inequality, pollution, policy and market failures,
prevention and management of natural disasters
Environmental Degradation and Poverty
The two cycles need to be broken if development
is to be sustainable
Good Governance
Accountability - answerable for their actions and behaviour
Participation & Decentralisation -
involvement of stakeholders and
redistribution away from a central
organisation - to local governance
Predictability - laws, regulations and policies must be fair and
consistently applied so that people can predict the
consequences and outcomes of violating them
Transparency - info on government
actions and policies before and after
action, must be available to the
general public
