The Importance of Ecologically Sustainable Development (HSC SSCE Legal Studies): Revision Notes
The Importance of Ecologically Sustainable Development
Origins of ecologically sustainable development
The Brundtland Commission and Report
In 1983, the United Nations established a commission to investigate how environmental degradation was affecting economic and social development worldwide. This commission, known as the World Commission on Environment and Development (WCED), was chaired by Norway's Prime Minister, Gro Harlem Brundtland.
In 1987, the commission released a landmark report titled Our Common Future, commonly known as the Brundtland Report. This influential document addressed a critical challenge: how could resources be distributed fairly to poorer nations and their economic growth encouraged, while simultaneously addressing environmental degradation and resource depletion that typically accompany development?
The commission's investigation was groundbreaking because it was one of the first major international efforts to recognize that environmental protection and economic development are not opposing forces, but rather must work together for sustainable progress.
The commission concluded that both economic development and environmental protection could be achieved together, but this would require fundamental changes. Both individuals' lifestyles and governments' policies regarding environmental impact would need to transform to achieve what became known as ecologically sustainable development (ESD).
Defining sustainable development
The Brundtland Report provided a definition that has become the foundation of sustainable development thinking:
Sustainable development is "development that meets the needs of the present without compromising the ability of future generations to meet their own needs."
This definition establishes a dual focus. ESD aims to address current societal needs, including poverty alleviation, while managing natural resources, energy and waste in ways that can continue indefinitely without destroying the environment or endangering human health. The concept recognises that present-day development decisions have long-term consequences for those who will inherit the planet.
The 1992 Rio Conference
Following the Brundtland Report, international commitment to ESD strengthened at the 1992 Rio Conference (also known as the Earth Summit). This conference produced five separate agreements that expanded upon ESD principles and committed signatory nations to implementing them:
- The Rio Declaration: Contains 27 principles designed to guide nation-states in environmental behaviour
- Agenda 21: A comprehensive 'work plan' outlining actions that can be taken at local, national and international levels to achieve ESD
- United Nations Framework Convention on Climate Change: Establishes a framework for international climate action
- United Nations Convention on Biological Diversity: Commits parties to protecting biodiversity
- Principles of Forest Management: Sets out guidelines for sustainable forest management
These five agreements collectively form the international legal foundation for ecologically sustainable development. They represent a comprehensive approach to environmental protection, addressing everything from climate change to biodiversity to sustainable resource management.
Central principles of ESD
While not explicitly listed as "four central principles" in a single document, four key principles have emerged from the Rio Conference agreements. These principles have been embraced by governments, international organisations, and environmental groups worldwide, including the Australian Government and state Environmental Defender's Offices.
It is crucial to understand that these principles work together as an integrated package rather than as isolated concepts.
Biodiversity
Biodiversity (biological diversity) refers to the variation of life forms on Earth. This includes the complete range of types possible within an ecosystem, biome or species. Understanding biodiversity requires knowledge of different ecological scales:
- An ecosystem consists of the relationships among plants, animals, micro-organisms and habitats in a relatively small area
- A biome is a much larger regional group of ecosystems spanning a wide geographic area
Biodiversity operates at multiple levels:
- Species diversity: The variety of different species in an area
- Habitat diversity: The range of different environments on Earth, such as deserts, forests, wetlands and rivers
- Genetic diversity: Variations within individual species, such as different breeds of cattle or varieties of wheat
The importance of biodiversity for sustainable development is multifaceted. Diverse ecosystems demonstrate greater productivity, which has significant implications for agriculture and food security. They show enhanced resilience, with better capacity to withstand and recover from environmental disasters. The interconnectedness of species within ecosystems contributes to the overall health of both the ecosystem itself and the life forms within it. Genetic variety within populations plays a vital role in health outcomes, for example by reducing the incidence of harmful mutations.
The UN Convention on Biological Diversity establishes three main objectives that parties commit to:
- Conservation of biological diversity
- Sustainable use of resources
- Fair and equitable sharing of benefits from genetic resources
Intergenerational equity
Intergenerational equity embodies the principle of fair and just treatment between different generations. In environmental terms, it centres on the idea that ecosystems and the environment should not be passed on in any worse condition from one generation to the next.
Principle 3 of the Rio Declaration articulates this concept by referring to development that meets the needs of both present and future generations. This principle establishes that decision-makers at any given time—including individual consumers and citizens—bear responsibility to those who will live in the future.
The concept challenges short-term thinking that prioritises immediate benefits without considering long-term environmental consequences.
Intergenerational equity requires present generations to consider how their resource use, pollution levels, and environmental management decisions will affect the quality of life and available resources for future populations. This principle fundamentally shifts environmental decision-making from a focus on current costs and benefits to a broader temporal perspective.
Intragenerational equity
In contrast to intergenerational equity, intragenerational equity focuses on fair and just treatment of different groups of people within the same generation. This principle recognises that environmental issues have important social justice dimensions.
Intragenerational equity is achieved through policies that work to:
- Raise the standard of living of disadvantaged peoples and nations
- Ensure that environmental management and resource use does not exploit particular groups
- Address disparities in how environmental benefits and harms are distributed
Several principles from the Rio Declaration address intragenerational equity:
Principle 5 calls upon states and individuals to cooperate in eradicating poverty, recognising it as a necessary condition for sustainable development.
Principle 8 articulates the duty to reduce and eliminate wasteful patterns of production and consumption, acknowledging that current consumption patterns in wealthy nations are unsustainable and inequitable.
Principle 6 states that international actions involving development and the environment should address the interests and needs of all countries, with particular attention to the special situation and needs of developing countries.
Principle 22 specifically addresses indigenous peoples and communities, recognising their cultural knowledge and traditional practices as valuable contributions to sustainable environmental management. States are required to recognise and support indigenous peoples' participation in ESD and acknowledge their unique contributions.
The precautionary principle
The precautionary principle represents a fundamental shift in how environmental risks are approached.
Principle 15 of the Rio Declaration states that "where there are threats of serious or irreversible damage [to the environment], lack of full scientific certainty shall not be used as a reason for postponing measures to prevent environmental degradation."
In practical terms, this means that when an activity raises the risk of serious environmental harm, but there is uncertainty about the likelihood or severity of that harm, a cautious approach should be adopted. Decision-makers should take steps to halt or modify the activity, even if they do not—and may never—know with certainty whether stopping or changing the activity was necessary.
The precautionary principle emerged as a response to environmental and health problems caused by rapid industrial growth after World War II, during a period when environmental legislation was weak or absent. Traditional approaches waited for definitive proof of harm before taking action, but the precautionary principle reverses this burden, prioritising prevention over reactive responses.
This principle is particularly important when dealing with:
- Irreversible environmental damage
- Long-term or delayed effects
- Complex ecosystems where cause-and-effect relationships are unclear
- Situations where the cost of inaction may be catastrophic
ESD in domestic law
National implementation in Australia
The principles of ESD have been firmly established in both international and domestic legal frameworks. Australia has been particularly proactive in incorporating ESD into national legislation and policy.
The most significant demonstration of ESD's importance at the national level in Australia is the National Strategy for Ecologically Sustainable Development, adopted by all levels of government in 1992. This strategy provides a comprehensive framework for implementing ESD principles across federal, state and local government operations.
It is essential to recognise that the four principles of ESD are not meant to be applied in isolation. They function as an integrated package, with each principle supporting and reinforcing the others.
Commonwealth legislation
The Environment Protection and Biodiversity Conservation Act 1999 (Cth) provides clear examples of how ESD principles have been incorporated into Australian law.
Section 136(2)(a) requires that the relevant Minister must consider the principles of ecologically sustainable development before deciding whether to approve any project, development, undertaking or activity, or changes to any of these.
Section 391(1) specifically requires the Minister to take account of the precautionary principle when making such decisions. Notably, this section defines the precautionary principle in nearly identical terms to Principle 15 of the Rio Declaration, demonstrating direct incorporation of international principles into domestic law.
State legislation
Various state laws also incorporate ESD principles. Key examples include:
- Fisheries Management Act 1994 (NSW): Applies ESD principles to fisheries management decisions
- Local Government Act 1993 (NSW): Requires local councils to consider ESD in their decision-making processes
These legislative provisions have resulted in numerous Land and Environment Court decisions in New South Wales that have either directly or indirectly applied ESD principles.
Case law application
Greenpeace v Redbank Power Co. (1995) 86 LGERA 143
This case demonstrates judicial application of the precautionary principle. The court considered a development application for a power plant and used the formulation of the precautionary principle contained in the Intergovernmental Agreement on the Environment. This agreement, entered into in 1992 by the federal government and all state and territory governments as part of the National Strategy for ESD, provided the legal basis for applying ESD principles in the case.
Leatch v National Parks and Wildlife Service (1993) 81 LGERA 270
This case provides a particularly strong example of the precautionary principle's application. A licence had been granted to "take or kill" endangered animals during a road development project. The court applied the precautionary principle and reversed the licence.
Significantly, although the Act under which the licence was granted did not explicitly refer to the precautionary principle, the court held that the principle applied "as a matter of common sense" and was one of the factors that the Act permitted the court to consider.
This demonstrates judicial willingness to apply ESD principles even when legislation does not explicitly mandate their application.
ESD and changing societal values
International recognition and programs
At the international level, ecologically sustainable development features prominently in numerous treaties and international initiatives. The United Nations declared a Decade of Education for Sustainable Development (2005-2014), demonstrating high-level commitment to promoting ESD principles globally.
UNESCO (United Nations Educational, Scientific and Cultural Organization) serves as the lead agency for this program, developing and disseminating educational materials on ESD for use by educators, professionals and organisations worldwide. The United Nations Environment Programme (UNEP) also treats ESD as a primary consideration in its work.
Evolution in environmental thinking
The development and application of ESD corresponds with a fundamental evolution in society's values regarding the environment and development.
The precautionary principle reflects a new consideration of the potential consequences of proposed activities beyond merely financial benefits. It represents a shift from reactive to proactive environmental protection, prioritising prevention even when complete scientific certainty is lacking.
Recognition of biodiversity's importance demonstrates growing understanding of the interrelationships between humans, other life forms and ecosystems. This moves beyond viewing nature simply as resources to be exploited toward recognising the intrinsic value and interconnectedness of all life forms.
Seeking intragenerational equity requires consideration of distribution issues across communities, indigenous peoples and nations. This includes not only goods and services but also equitable access to a healthy environment. It challenges development models that benefit some groups while imposing environmental costs on others.
Addressing intergenerational equity illustrates a shift from short-term thinking to formulating policies and laws based on the well-being of future generations. This represents a fundamental change in how society weighs present benefits against future costs.
Key Points to Remember:
- ESD is defined as development that meets present needs without compromising future generations' ability to meet their own needs
- The four central principles work together as an integrated package: biodiversity, intergenerational equity, intragenerational equity, and the precautionary principle
- The Brundtland Report (1987) and Rio Conference (1992) established the international framework for ESD
- Australian domestic law incorporates ESD principles through the National Strategy for ESD and legislation such as the Environment Protection and Biodiversity Conservation Act 1999 (Cth)
- The precautionary principle shifts the burden of proof—action should be taken to prevent serious environmental harm even without complete scientific certainty
- Case law demonstrates that courts will apply ESD principles even when legislation does not explicitly require it
- ESD reflects an evolution in societal values from short-term, profit-focused thinking to long-term sustainability and equity considerations
