The Evolution Of Environmental Law: A Historical Perspective

Environmental law has evolved from a modest adjunct of public health regulations to an almost universally recognised independent field. While the term environmental law was not formally coined until 1969, the history of environmental law dates back to ancient times, with early examples of environmental protection found in Roman, English, and colonial American laws.

Throughout history, governments have passed laws to safeguard human health and the environment from the adverse effects of human activities. For instance, in AD 80, the Senate of Rome passed legislation to protect the city's supply of clean water. Similarly, in the 14th century, England prohibited coal burning and waste disposal into waterways in London.

The development of environmental law accelerated in the 20th century, particularly from the 1960s to the 1980s, with the emergence of the environmental movement and a growing public consciousness about ecological issues. During this period, significant environmental disasters, such as the 1969 Santa Barbara oil spill, and influential publications like Rachel Carson's Silent Spring, galvanised public outrage and spurred legislative action.

The creation of environmental protection agencies, such as the United States Environmental Protection Agency (EPA), and the enactment of landmark environmental statutes like the Clean Air Act, Clean Water Act, and the National Environmental Policy Act, further solidified the establishment of environmental law as a distinct and essential field.

Today, environmental law encompasses a broad range of topics, including air and water quality, waste management, chemical safety, and the management of natural resources. It operates at local, national, and international levels, reflecting the global recognition of the importance of protecting the environment and human health from the potential harms caused by human activities.

The history of environmental law

Ancient Times to the 19th Century

Even in ancient times, governments recognised the importance of protecting the environment. For example, around 80 AD, the Senate of Rome passed legislation to safeguard the city's supply of clean water for drinking and bathing. In the 14th century, England prohibited the burning of coal in London and the disposal of waste into waterways. Fast forward to the 19th century, and we see the British government, amidst the Industrial Revolution, passing regulations to mitigate the harmful effects of coal burning and chemical manufacturing on public health and the environment.

Early 20th Century

During the early 20th century, international environmental agreements began to emerge, focusing primarily on the protection of commercially valuable species. Notable examples include the 1902 Convention for the Protection of Birds Useful to Agriculture and the 1916 Convention for the Protection of Migratory Birds.

1960s to 1970s

The 1960s and 1970s witnessed a significant shift towards environmentalism as a prominent political and intellectual movement in the West. The publication of Rachel Carson's "Silent Spring" in 1962 played a pivotal role in raising awareness about the dangers of pesticides and their impact on the environment. This, along with highly visible environmental disasters such as the 1969 Santa Barbara oil spill, galvanised public support for environmental protection.

In the United States, the 1970s marked a seminal decade for environmental legislation. On January 1, 1970, President Richard Nixon signed the National Environmental Policy Act (NEPA), kicking off a decade of environmental reforms. This was followed by the creation of the Environmental Protection Agency (EPA) later that year, which consolidated various environmental programs into a single entity. The Clean Air Act, the Clean Water Act, and the Endangered Species Act are among the landmark laws passed during this period.

1980s to 1990s

The 1980s saw a period of controversy and challenges to environmental laws, with President Ronald Reagan aligning himself with opponents of federal ownership of public lands. Despite this, environmental laws continued to expand, with the Comprehensive Environmental Response, Compensation, and Liability Act addressing the toxic waste crisis.

The 1990s brought about a change in the political landscape, with partisan gridlock hindering legislative progress. However, international environmental law gained prominence, with the United Nations listing approximately 1,000 international environmental agreements by the end of the decade.

2000s to Present

In the 21st century, global warming and climate change have emerged as pressing issues, requiring international cooperation and sweeping domestic and international laws. Despite the challenges, environmental law has demonstrated resilience and continues to evolve to address the complex ecological challenges of our time.

International environmental law

The history of IEL can be divided into three stages, separated by two of the most relevant international conferences held so far: the Stockholm Conference (1972) and the Rio de Janeiro Earth Summit (1992).

Before the 1960s

Before the 1960s, there was little environmental awareness and only a few isolated international environmental regulatory initiatives. One notable example was the failed London Convention of 1900, which aimed to protect African wildlife but never came into force as it was not signed by the minimum number of parties.

The 1960s and 1970s

Things began to change in the 1960s as public opinion became more aware of the dangers threatening the planet. The publication of biologist Rachel Carson's *Silent Spring* in 1962, which documented the negative effects of pesticides on the environment, was a pivotal moment. The release of the image "Earthrise", taken by astronaut William Anders during the Apollo 8 mission in 1968, also had a significant impact.

In the late 1960s and early 1970s, the United States passed a significant number of environmental laws, including acts addressing solid-waste disposal, air and water pollution, and the protection of endangered species. The establishment of the Environmental Protection Agency (EPA) in 1970 to monitor compliance with these laws marked the beginning of the "environmental decade".

The 1972 United Nations Conference on the Human Environment in Stockholm was a pivotal moment in the development of IEL. The resulting Stockholm Declaration was the first international document to recognize the right to a healthy environment through 26 principles, many of which have played a crucial role in the subsequent development of IEL.

Following the Stockholm Conference, European countries, which had previously been slow to enact legal standards for environmental protection, began to balance the goal of economic expansion with the need to protect the environment.

The 1980s and 1990s

During the 1980s, the "transboundary effects" of environmental pollution in individual countries spurred negotiations on several international environmental conventions. The 1986 accident at the Chernobyl nuclear power plant in Ukraine had a significant impact, forcing European countries in the path of the pollution to adopt measures to restrict their populations' consumption of certain foods and drinks.

In 1987, the Montreal Protocol was signed to combat the depletion of the ozone layer, and it is believed that due to this agreement, the ozone layer could recover by 2050.

In 1992, the Rio de Janeiro Earth Summit resulted in the signing of two important conventions: the Convention on Biological Diversity and the United Nations Framework Convention on Climate Change (UNFCCC). The Rio Declaration, which reaffirmed the Stockholm Declaration, also established the Precautionary Principle and Principle 10, recognizing the right to information, participation, and justice in environmental matters.

2000s to Present

In the 2000s, international environmental issues continued to be the subject of international law and numerous agreements. In 2016, with the signing of the Paris Agreement, a new stage began to address humanity's most pressing natural challenge: the current climate emergency.

Despite these global initiatives, the serious environmental crisis we are experiencing persists, and it is unclear if future generations will be able to meet their needs as past and present generations have.

Environmental law in the US

The Early Years and Roots of Environmental Law:

The roots of environmental law in the US can be traced back to early common law doctrines, such as the law of nuisance and the public trust doctrine. The first statutory environmental law was the Rivers and Harbors Act of 1899, which focused on water pollution and was later superseded by more comprehensive legislation.

The Emergence of Modern Environmental Law:

The modern environmental movement in the US gained momentum in the early 1960s, sparked by publications like Rachel Carson's "Silent Spring" in 1962, which highlighted the dangers of pesticide use. This period also witnessed highly visible environmental disasters, such as the 1969 Santa Barbara oil spill, which generated public outrage and spurred legislative action.

The Formative Decade: 1970s:

The 1970s was a seminal decade for environmental protection in the US, with three significant milestones: the National Environmental Policy Act (NEPA), the Clean Air Act, and the establishment of the Environmental Protection Agency (EPA). NEPA, often referred to as the "Magna Carta of environmental law," set a broad national policy to protect the environment and required federal agencies to assess the environmental impacts of their actions. The Clean Air Act addressed air pollution, while the creation of the EPA consolidated various environmental programs into a single entity, giving more focus and coordination to environmental efforts.

This decade also saw the passage of nearly two dozen environmental laws with overwhelming bipartisan support, including the Clean Water Act, the Endangered Species Act, the Natural Forest Management Act, and the Marine Mammal Protection Act. These laws demonstrated a strong commitment to conservation and the protection of natural resources.

Controversy and Challenges:

Despite the significant progress in the 1970s, controversy and challenges emerged. Some critics argued that the pace of change was too slow, while regulated industries pushed back against the reach of the EPA. Additionally, the federalist and regulatory reform movements gained traction, leading to shifts in political support for environmental initiatives.

The 1980s and Partisan Divisions:

The 1980s marked a period of increasing partisanship and challenges to environmental law. President Ronald Reagan aligned himself with the "Sagebrush Rebels," who opposed federal ownership of public lands. His administration took steps to suspend regulations, encourage cost-benefit analysis, and give more authority to the Office of Management and Budget in shaping environmental policies. The heads of the Interior Department and EPA during this period were openly hostile towards environmental protection efforts. While some reversals of environmental protections occurred, the overall body of environmental law persisted and continued to expand.

The 1990s and Gridlock:

The 1990s brought about a change in the political landscape, with Republican control of Congress. This period was marked by controversy, gridlock, and the demise of bipartisanship on environmental issues. President George H. W. Bush initially showed support for environmental initiatives but later proposed drilling in the Arctic National Wildlife Refuge. President Bill Clinton took a different approach, but conflicts with Congress and the courts led to a stalemate on many environmental goals. This decade also saw the emergence of international environmental law as a dynamic area, with a growing number of international agreements.

The 21st Century and Global Warming:

The 21st century brought new challenges, with global warming and climate change taking center stage. While there have been efforts to address these issues, such as the Paris Agreement, the Trump administration's policies rolled back many environmental protections. However, the Biden administration has made strong commitments to protecting the environment and addressing climate change.

Overall, the history of environmental law in the US has been marked by both progress and setbacks. The complexity of ecological systems and the dynamic political landscape have influenced the development of this field of law. Despite the challenges, environmental law in the US has demonstrated resilience and a persistent pursuit of protecting human health and the natural environment.

Environmental law principles

Environmental law is a collection of laws, regulations, agreements, and common law that govern how humans interact with their environment. Here are some key principles of environmental law:

Sustainable Development

Sustainable development is defined by the United Nations Environment Programme (UNEP) as "development that meets the needs of the present without compromising the ability of future generations to meet their own needs." This principle recognises that development must be considered alongside sustainability and interdependence, acknowledging that social and economic development is interdependent with environmental protection.

Transboundary Responsibility

Transboundary responsibility, as defined by UNEP, is the obligation of nations to protect their own environment and prevent damage to neighbouring environments. This principle acknowledges the potential limitation on the rights of sovereign states in the context of international law.

Public Participation and Transparency

Public participation and transparency are essential for accountable governments and organisations. UNEP emphasises the need for effective protection of the human right to express opinions, access relevant environmental data, and engage in judicial and administrative proceedings related to environmental issues.

Precautionary Principle

The precautionary principle, as formulated in the Rio Declaration, states that "where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation." This principle is particularly relevant when there is uncertainty about the potential environmental impact of certain activities.

Prevention Principle

The prevention principle recognises that preventing environmental harm is cheaper, easier, and less dangerous than reacting to it. This principle underlies laws regulating hazardous waste management and pesticide use.

Polluter Pays Principle

The "polluter pays" principle asserts that the environmental costs of economic activities should be internalised rather than imposed on society. It aims to ensure that polluters bear the real costs of their pollution, encouraging the development of cleaner products and technologies.

The future of environmental law

Environmental law has evolved from a niche field focused on public health regulations to an essential and widely recognised independent domain safeguarding human health and nature. This evolution has been driven by growing environmental awareness and concerns, with the 1960s marking a pivotal period for the emergence of environmentalism as a significant political and intellectual movement in the West. As we look ahead, what does the future hold for environmental law?

Sustainable Development and Intergenerational Equity

The concept of sustainable development, introduced at the 1972 United Nations Conference on the Human Environment, remains a cornerstone of international environmental discussions. Sustainable development entails meeting the needs of the present while safeguarding the ability of future generations to meet their own needs. This principle underscores the interconnectedness of social, economic, and environmental considerations. Environmental laws will continue to play a pivotal role in mandating environmental impact assessments and encouraging development that minimises ecological harm.

Transboundary Responsibility and International Cooperation

Addressing global environmental challenges requires international cooperation and the recognition of transboundary responsibility. Transboundary responsibility, as defined by the United Nations Environment Programme (UNEP), entails protecting one's own environment and preventing harm to neighbouring environments. This principle has been particularly relevant in addressing issues such as air and water pollution, where pollution from one country can affect the environments and health of others. International environmental agreements and organisations, such as the Kyoto Protocol and the United Nations Environment Programme (UNEP), will continue to be crucial in tackling these transboundary issues.

Public Participation and Transparency

Public participation and transparency are essential for effective environmental governance. UNEP emphasises the right to hold and express opinions, access relevant environmental data, and engage in decision-making processes. This principle has been reflected in various environmental impact assessment laws and administrative procedures. Going forward, public involvement in policy changes and governance will remain vital to address ecological challenges.

Precautionary Principle and Prevention

The precautionary principle, formulated in the Rio Declaration, states that the lack of full scientific certainty should not delay the implementation of cost-effective measures to prevent environmental degradation. This principle has been controversial, as it involves taking action despite uncertainties. However, it underscores the importance of prevention, which includes prior assessment of environmental harm, licensing, and the adoption of strategies to minimise environmental impacts.

Polluter Pays Principle and Economic Considerations

The polluter pays principle asserts that the costs of environmental damage and pollution prevention should be internalised by the responsible parties rather than imposed on society. This principle has been a point of contention, especially regarding carbon emissions and corporate accountability. Balancing environmental protection with economic considerations will continue to be a challenge, and debates around the fairness and cost of environmental regulations will persist.
