Pollution And Property Rights: A Complex Relationship

Property rights and pollution are related in that property rights are a tool for protecting the environment. In the past, property rights were used to protect against unwanted trespass or interference with the enjoyment of private property. For example, if someone dumped toxins in a river, downstream property owners could sue, demanding that they stop and pay for the damage caused. However, in the 19th century, US courts eroded those protections, allowing polluters to discharge invisible materials with little consequence. Today, economists and environmental regulators consider pollution as an issue of tradable rights, and the property rights approach to pollution has led to prominent successes. Courts can restore protections and award pollution damages based on transparent, scientific evidence, but this requires scientists to participate more actively in the legal system.

Courts can provide a transparent, evidence-based forum for resolving pollution disputes

Courts are increasingly being used to resolve disputes relating to climate change and pollution. A German appeals court, for example, is set to hear climate science evidence related to the threat of flooding from a glacial lake and the potential contribution of RWE to the problem. In another case, the Brazilian Superior Court of Justice prohibited setting fires to harvest sugar cane.

Scientific evidence is required to identify the effects of pollutants and provide data so that economists can calculate the costs of the direct and secondary effects of the pollutants, including property damage and personal injuries. For example, in the case of a coastal landowner, it would be sufficient to show that a facility is emitting pollutants capable of contributing to climate change, reserving for the merits whether damage to the landowner’s property is due to climate change and whether the amount of the facility’s emissions is a significant contribution.

However, there are challenges to using the courts to resolve pollution disputes. Judges are not equipped to handle highly technical factual issues unaided. In areas of ongoing research, such as the effects of various pollutants on human health and welfare, later scientific and technical developments could change the causation analysis. Judges and juries would benefit from a full fact-finding process, with Daubert hearings and other supporting procedures to ensure that the facts presented to the court reflect scientific methods and expertise as accurately as possible.

There has also been substantial disagreement in the courts and among commentators about the degree of inquiry required in the standing phase of an environmental claim. In particular, it is difficult to determine when adjudication of a factual dispute over causation should occur, in the standing phase or afterwards on the merits. In environmental suits, causation is typically analyzed as a component of Article III standing, a jurisdictional inquiry that precedes any other aspect of the case. However, this has created a significant and sometimes inappropriate barrier for environmental plaintiffs.

Scientific evidence is essential for identifying effects, calculating costs, and determining remedies

Scientific evidence is essential for identifying the effects of pollution, calculating costs, and determining remedies. For instance, scientific studies have demonstrated the toxicity hazards, environmental persistence, and accumulation in the human food chain of Perfluoro-octanoic acid (PFOA), an industrial chemical used in various manufacturing processes. As a result, its use was largely phased out by 2015.

Scientific evidence is crucial for understanding the impact of pollution on human health and the environment. For example, ammonia from animal feedlots affects respiratory health, while nitrate used on farms creates aquatic "dead zones". Mercury from coal-fired power plants causes developmental and neurological problems in children. Scientific research helps identify these pollutants and their effects, providing a basis for action.

Additionally, scientific evidence is necessary for calculating the costs associated with pollution. Economists rely on data from scientific studies to assess the direct and indirect costs of pollution, including property damage and personal injuries. This information is vital for policymakers and regulators in their decision-making processes.

Furthermore, scientific evidence plays a key role in determining effective remedies for pollution. For example, the identification of PFOA's hazards led to its phased elimination. Similarly, recognizing the impact of ammonia, nitrate, and mercury pollution can inform regulations and technologies to mitigate their effects. Scientific advancements also enable the development of innovative solutions, such as green technologies and sustainable practices.

The role of scientific evidence in addressing pollution is also evident in the legal system. Courts rely on scientific expertise to make informed decisions and award damages in pollution cases. By considering scientific evidence, courts can restore protections and hold polluters accountable, ensuring comprehensive remedies such as monetary damages, studies, monitoring, and security for future damages.

Property rights can incentivise sustainable practices and conservation

Property rights are essential for incentivising sustainable practices and conservation. When individuals or communities have clearly defined and enforceable property rights, they are more likely to feel a sense of obligation to care for and protect their land, resources, and the environment. This sense of responsibility can lead to the adoption of sustainable practices and conservation efforts to maintain the health and productivity of their assets.

For example, in the Philippines' zanjera irrigation community, the government granted a farming community ownership over the water supply. The farmers then established rules governing water usage, withdrawing water in rotation under supervision, avoiding overexploitation of the local water source and ensuring sustainable water management. Similarly, the recognition of property rights in fisheries has prevented the tragedy of the commons in marine fisheries by aligning the owners' incentives with the value of the underlying resource.

Property rights also provide economic incentives for sustainable practices and conservation. Owners of land or resources can benefit directly from the productive and sustainable use of their assets. For instance, local farmers in France have been paid by Evian Natural Mineral Water to preserve water quality through sustainable agricultural practices. This creates a financial motivation for farmers to adopt environmentally friendly methods, as they can capture some of the benefits of sustainable resource management.

Furthermore, property rights can help address pollution issues by providing a legal framework for recourse and compensation. When polluters infringe upon the property rights of others, such as through air or water pollution, property owners can seek legal action and demand that the polluter ceases their harmful activities and compensates them for any damages incurred. This discourages pollution and holds polluters accountable for their actions, encouraging them to adopt cleaner practices.

While property rights provide a strong foundation for incentivising sustainable practices and conservation, it is important to recognise that their implementation can be complex, particularly in situations involving multiple parties or externalities. Nonetheless, with clear definitions, effective enforcement, and the support of legal and regulatory systems, property rights can play a pivotal role in promoting environmental stewardship and sustainable resource management.

Polluters should internalise the costs imposed on others

The concept of property rights has been used to address environmental issues and curb pollution. Economists and environmentalists have advocated for the treatment of pollution as a property rights issue, which has led to successes in various areas. This approach involves recognizing that imposing waste or emissions on another's land is a violation of their rights.

Pollution, particularly invisible pollutants like ammonia, nitrates, and mercury, can easily cross property lines and cause harm far from their sources. This results in societal and environmental consequences, including health issues, reduced crop yields, harm to ecosystems, and long-term effects on climate change. To promote societal well-being, it is essential to minimize social costs and maximize social returns.

When polluters do not internalize the indirect costs of their actions, market inefficiencies occur, leading to overproduction or underproduction. Neoclassical economists have recognized this as a form of "market failure," and British economist Arthur Pigou suggested that governments should tax polluters an amount equivalent to the harm caused to others. This tax would correct the market defect and yield efficient market outcomes.

Similarly, Milton Friedman proposed that society, through the government, should charge polluters the costs of cleanup and environmental damage. This can be achieved through pollution taxes and discharge fees, forcing polluters to internalize the environmental costs of their activities. By implementing such measures, polluters will have an incentive to reduce harmful activities and develop cleaner technologies.

In practice, determining the monetary value of environmental damage can be challenging. However, alternative strategies such as setting up a trade in pollution permits are also being explored. While these approaches may not provide direct control over pollution levels, they promote the adoption of cleaner practices and technologies.

Clear property rights can prevent environmental degradation

Clear property rights are essential for preventing environmental degradation and promoting sustainable practices. When individuals or communities have well-defined and enforceable property rights, they are incentivized to sustainably manage and conserve their resources. This alignment of incentives encourages resource conservation and discourages harmful pollution, as individuals are less likely to engage in activities that degrade their own property.

Historically, property rights have provided primary protections against pollution through guarantees against unwanted trespass or interference with the enjoyment of private property. For example, if a factory emitted pollutants that contaminated a nearby river, downstream property owners could take legal action, demanding that the polluter cease their harmful activities and compensate for the damage caused. This accountability helps to prevent environmental degradation and promotes responsible practices.

However, in the 19th century, courts in the United States weakened traditional property rights, particularly regarding invisible trespassers like chemical pollutants. This erosion of rights allowed industries to discharge harmful chemicals with little consequence, resulting in a market failure where the true costs of production were masked, burdening society with property damage and health issues.

To address this challenge, economists and environmentalists have advocated for a property rights approach to pollution. This perspective treats pollution as a tradable right, empowering affected parties to negotiate and seek cost-effective solutions. For instance, in the case of a railroad emitting sparks that land on a farmer's crops, the farmer could have the right to demand that the railroad implement spark arrestors or compensate them for the inconvenience.

Clear property rights also help prevent the tragedy of the commons, a scenario where the lack of ownership leads to overexploitation of resources. By assigning property rights, communities can establish sustainable practices and resolve conflicts through local courts. For example, granting ownership of a water supply to a farming community in the Philippines encouraged them to create rules governing water withdrawal, avoiding overexploitation and ensuring equitable access.

In conclusion, clear and enforced property rights are crucial for preventing environmental degradation. They provide incentives for sustainable resource management, deter pollution, and empower individuals to seek legal recourse when their rights are violated. While challenges and complexities exist, a commitment to protecting property rights is a powerful tool in the fight against environmental degradation.
