Air Pollution: A Threat To Human Sustainability With Special Reference To Delhi NCR

Lead, sulphur oxides, nitrogen oxides, carbon monoxide, particulate matter, and ground-level ozone are the six main air pollutants according to the World Health Organization (WHO). The consequences of these pollutants on the air, soil, and water are widespread. They worsen global warming, have an influence on human health, and contribute to climate change and the greenhouse effect. Because of air pollution, acid rain, global warming, the greenhouse effect, and climate change have a substantial impact on ecosystems.

Following exposure to these contaminants, neurological consequences are seen in both adults and children. Global air pollution is a result of the damage that human activity is doing to the air, water, and land. Because of the serious consequences that these pollutants have for both the environment and human health, this study concentrates exclusively on them. The natural, physical, chemical, and biological components of our surrounds are all included in the environment. Every living thing adjusts to its own surroundings according to what is appropriate. Pollution-related environmental damage, however, is a developing worry.

Pollutants are substances that cause considerable harm to the environment and human health. They might take the shape of liquids, solids, gasses, sediments, dust, or other materials. The leftovers or results of human activity are frequently the source of these contaminants. Air pollution is one of the main forms of pollution among others. Air pollution, especially in metropolitan areas, has increased due to factors such as industrialization, population growth, and vehicle emissions.

Cities like Delhi, which struggle with serious air quality problems, such as dangerously high pollution levels, are prime examples of this decline. The severity of the issue is highlighted by the increase in the Air Quality Index (AQI) and the health concerns that are linked to it, including respiratory infections and asthma. The government has taken steps to reduce air pollution and enhance the quality of the air for the sake of public health.

The introduction of hazardous chemicals into the environment that have a negative impact on living things is referred to as "pollution". When this phenomena happens in larger quantities, life quality is considerably reduced. The issue of environmental pollution is a complex global health hazard that is mostly caused by human activities, urbanization, and population expansion. All these things add to air pollution, which is one of the biggest threats to global public health and kills about 9 million people a year.

Developmental activities have a negative influence on vital environmental elements like water, air, and soil even as they propel human growth through scientific and technical breakthroughs. The industrial revolution has caused significant environmental damage in addition to its well-known revolutionary effects on society and technical advancement. Large amounts of dangerous pollutants have been released into the environment as a result of the expansion of industrial activity, posing serious health dangers to people. In emerging nations, when issues with excessive population growth, fast urbanization, and industry spread worsen air pollution, the situation is more dire.

Legally speaking, combating environmental pollution necessitates an all-encompassing framework that includes legislative, regulatory, and enforcement tools. International treaties and agreements are essential for coordinating worldwide pollution control activities. These agreements frequently provide rules and specifications for waste management, pollution emissions, and environmental protection measures. To reduce pollution and protect the environment and public health, national governments pass laws and regulations. Statutes pertaining to land use planning, hazardous waste management, water pollution control, and air quality regulations are a few examples of these legal tools. Enforcing these regulations, keeping an eye on compliance, and levying penalties for infractions are the responsibilities of regulatory bodies.

The atmosphere that surrounds us is referred to as the environment. It is divided into six separate levels, which are the troposphere, stratosphere, mesosphere, thermosphere, exosphere, and ionosphere. Of them, the troposphere�which rises to a height of about 10 kilometers above sea level�is essential to human existence because it has the oxygen required for breathing. But as time goes on, this once-pure atmosphere is facing a serious pollution catastrophe that will only get worse. Pollution may take many different forms, and each one contributes differently to the deterioration of the ecosystem. Pollution is often divided into three types: air pollution, water pollution, and soil contamination.

These categories are based on the effects that pollution has on various environmental components. Pollutants are chemicals that cause pollution. They might be gases, liquids, solids, dust, sediments, or other hazardous compounds that are bad for the environment and human health. Pollutants are frequently waste products or leftovers from human consumption and disposal.

Finding the causes of pollution is a complex task since some of its origins are well-known while others are not. The main sources of pollution include emissions from thermal power plants and automobile engines, as well as rivers, lakes, and other bodies of water contaminated by industrial waste and effluents. Environmental pollution is largely caused by human activity, but it is sometimes a result of natural events like earthquakes and volcanic eruptions.

To reduce pollution and protect the environment and public health, national governments pass laws and regulations. It is crucial to implement legislative measures that address hazardous waste management, water pollution control, air quality requirements, and land use planning. In order to enforce these regulations, monitor compliance, and impose fines for infractions, regulatory bodies are essential.

By internalizing the external costs of pollution and encouraging attempts to reduce it, economic tools like pollution levies, carbon trading systems, and environmental impact assessments support regulatory actions. Legal frameworks can also include provisions for environmental justice, stakeholder involvement, and public participation to guarantee accountability and openness in decision-making.

Civil, criminal, and administrative enforcement proceedings are among the legal remedies available for environmental contamination. Affected parties may use civil responsibility to pursue damages, injunctive relief, or court-mandated environmental repair through legal action. If someone or anything violates the law intentionally or negligently, they may face criminal consequences, which might include fines, jail time, or the cancellation of their operating permits. Administrative enforcement actions entail directions from regulatory bodies to stop polluting operations, repair environmental damage, or adhere to regulations; non-compliance results in more enforcement actions.

In order to hold polluters responsible for environmental harm and to obtain compensation for impacted communities, litigation is essential. Individuals, communities, or environmental groups can jointly pursue legal action against liable parties through civil lawsuits, including class actions, in order to obtain compensation, injunctive relief, or environmental restoration.

Therefore, combating environmental pollution necessitates a multimodal legal strategy that includes national and international laws, financial incentives, and enforcement tools. To ensure accountability, compliance, and sustainable development practices for current and future generations, effective environmental governance depends on strong legislative frameworks, regulatory monitoring, and judicial systems.

Harmful Effects of Air Pollution:

Air pollution is a serious problem, especially when it comes to environmental and health issues, especially in poor countries. The World Health Organization (WHO) said that ambient air pollution was a contributing factor in approximately 3 million deaths globally in 2012. Anthropogenic activity is the main cause of this widespread problem. Air pollution has a devastating effect on people's health, causing a wide range of conditions from respiratory infections to asthma and chronic obstructive pulmonary disease, as well as higher hospitalization rates. Extended exposure to air pollutants aggravates lung and cardiovascular problems. Research suggests that prolonged exposure to air pollutants increases the risk of diabetes.

In addition, the increasing release of greenhouse gases, particularly CO2, has become an urgent worldwide issue. Global warming is fueled by the growth in carbon emissions, which is a contribution from almost every country. As a result, CO2 emissions rise, which raises temperatures and exacerbates environmental problems including smog, acid rain, respiratory illnesses, and a depleted ozone layer. All of these factors ultimately contribute to global warming. While long-term exposure increases the risk of chronic asthma, pulmonary conditions, and cardiovascular disorders, short-term exposure causes symptoms including coughing, shortness of breath, and asthma.

Air pollution damages the ecosystem in ways that go beyond harm to human health. Because of the nitric and sulfuric acid emissions that cause acid rain, ecosystems are seriously threatened. Plants and marine life are corroded, and infrastructure is damaged. Ground-level ozone interferes with photosynthesis and the transfer of CO2 in plants, and it is well known for its detrimental impacts on human health as well as plant life. The greenhouse effect is driving global climate change, which puts biodiversity, agriculture, and animals at serious danger. Development efforts also increase greenhouse gas emissions[1].

Animals are also heavily affected by air pollution, since excessive pollutant levels can lead to birth abnormalities and reproductive failures. Eutrophication is a serious hazard to aquatic ecosystems, reducing fish populations and productivity. It is an ecological imbalance brought on by nitrogen runoff that stimulates algal blooms.

The effects of air pollution are, in essence, ubiquitous across the ecosystem, with far-reaching implications for human health. Global warming threatens biodiversity, acid rain damages ecosystems, and ground-level ozone depletes photosynthesis. Understanding the complex effects of air pollution highlights the pressing need for all-encompassing regulatory frameworks to address this persistent issue. Strong environmental laws are essential to protecting human health and ecological integrity in a world that is becoming more and more polluted. They should regulate emissions and promote sustainable behaviors, among other things.

Legislative Measures pertaining to Air Pollution

International Law:

  • Often referred to as the "Magna Carta of the Environment," the Stockholm Conference of 1972 represents a turning point in the history of the environment. This historic occasion committed the world to tackling urgent environmental issues by emphasizing sustainable development and environmental conservation. The creation of Agenda 21, a comprehensive action plan intended to prevent environmental deterioration and promote sustainable behaviors, was one of the conference's main results.
  • A coordinated effort to confront the growing threat of climate change was signaled in 1994 with the establishment of the United Nations Framework Convention on Climate Change (UNFCCC). Stabilizing the atmospheric quantities of greenhouse gases, which had increased as a result of rapid industrialization and human activity, was the main goal of this protocol. Later, in 1997, the Kyoto Protocol was adopted, placing legally-binding obligations on industrialized nations to cut back on greenhouse gas emissions. This helped to support the campaign.
  • The Kyoto Protocol, which acknowledged that industrialized countries have historically been mostly responsible for the majority of greenhouse gas emissions, marked a critical turning point in international climate action. The convention sought to resolve differences in emissions contributions and promote equitable burden-sharing in the fight against climate change by imposing legal requirements only on industrialized nations.
  • In response to the pressing need to address ozone depletion, the Montreal Protocol on Substances that Deplete the Ozone Layer was developed in 1985. This protocol sought to control the manufacture and use of certain chemicals, such as halons and chlorofluorocarbons (CFCs), that are known to contribute to ozone depletion. The goal of the Montreal Protocol was to prevent further ozone depletion and preserve the Earth's protective ozone layer by limiting the use of certain ozone-depleting compounds.

Legally speaking, these international accords and guidelines serve as vital tools for tackling environmental issues worldwide and advancing sustainable growth. They provide legally enforceable agreements, a framework for international collaboration, and procedures for oversight and enforcement. Furthermore, they emphasize the idea of shared but distinct responsibilities, acknowledging the various capacities and contributions of different countries to environmental deterioration and climate change.

Hence, the ideas of sustainability and environmental preservation are advanced by the Stockholm Conference, UNFCCC, Kyoto Protocol, and Montreal Protocol, which serve as cornerstones of international environmental legislation and influence how the world responds to environmental problems. The international community has shown that it is committed to working together to protect the planet for both the present and the future generations by using these legal tools.

National Law:

  • India's legal achievement in environmental protection is marked by the Environment Protection Act of 1986. A comprehensive legal framework for environmental protection has been established as a result of this law, which was enacted under Article 253 of the Indian Constitution. It reflects the rising national concern for environmental concerns in recent years.
  • In addition, the 1986 Air (Prevention and Control) Act tackles the urgent requirement to counteract air pollution. This law gives the state and federal pollution control boards as well as the central pollution control board the authority to regulate and impose policies meant to prevent and manage air pollution. The Act outlines these authorities' various roles and duties with regard to resolving issues with air quality and making sure pollution control measures are followed.

Air Pollution (Prevention and Control) Act, 1981

Enacted under Article 253 of the Indian Constitution, the Air (Prevention and Control) Act of 1986, often known as the Air Act, is a noteworthy legislative measure. India's determination to implement the resolutions from the June 1972 United Nations Conference on the Human Environment in Stockholm served as the impetus for its founding. This Act provides India with a vital legislative foundation for combating air pollution and preserving the country's natural ecosystem.

Definitions essential to comprehending the Air Act's goals and extent are provided in Section 2. "Air Pollutant" is defined as any dangerous, hazardous particle that is present in the atmosphere and endangers the ecosystem. Similarly, the definition of "air pollution" emphasizes that any air pollutant present in the atmosphere emphasizing the Act's focus on controlling and mitigating pollutants that degrade air quality.

The Central Pollution Control Board's (CPCB) function is essential to the Air Act's execution. The CPCB's responsibilities are delineated in Section 16 of the Act, encompassing the enhancement of air quality as well as the prevention, control, and mitigation of air pollution nationwide. This clause emphasizes the central government's resolve to use coordinated regulatory actions to reduce air pollution at the local, state, and federal levels. Legal precedents also clarify how the Air Act should be interpreted and enforced. Section 19 of the Air Act was used to declare some parts of Delhi as pollution control zones in the historic case of M.C. Mehta v. Union of India[2], also referred to as the Oleum gas leaking case. The operation of the Shriram fertilizers factory was banned because of a leakage of oleum gas, highlighting the Act's provisions for regulating industrial activities to prevent environmental harm.

In addition, the court's involvement in M.C. Mehta v. Union of India[3] serves as an example of the judiciary's function in guaranteeing adherence to the Air Act. The court ordered the CPCB and Uttar Pradesh Pollution Control Board to look into the reasons behind the ineffectiveness of air quality monitoring systems in Delhi, including the possible influence of surrounding brick industries. This illustrates the judiciary's proactive approach to upholding environmental laws and making authorities responsible for resolving pollution-related issues.

Important facets of the Air Act's execution are further clarified by the various high courts' legal interpretations of the Act. The need of informing the public about pollution control measures specified under the Act was underscored by the Karnataka High Court in the case of Chaitanya Pulverizing Industry v. Karnataka State Pollution Control Board[4]. This emphasizes how important openness and citizen involvement are to environmental stewardship.

Similar to this, the Supreme Court made clear how pollution control areas are declared in Orissa State (Prevention and Control) Board v. Orient Paper Mills[5]. To ensure that pollution is effectively regulated in compliance with the Act, the state government has the right to declare such locations through formal gazette notifications in the event that an appropriate authority is not present.

The division of authority between the federal and state governments in executing pollution control measures is further highlighted by court rulings like Animals Feeds Diaries and Chemical Ltd. v. Orissa State Pollution Control Board[6]. The state government cannot give directives to manage pollution without the necessary legal permission, even though both levels of government have the jurisdiction to designate regions under control for pollution.

In addition, the Air Act is reinforced by constitutional clauses that underscore the need of Indian citizens to safeguard the environment. The Indian Constitution's Article 51A(g) emphasizes that it is every citizen's responsibility to preserve and enhance the natural environment, which includes forests, rivers, lakes, and animals. It was added following the 42nd Amendment Act of 1976[7]. This constitutional obligation emphasizes how crucial personal accountability is to preserving the environment for future generations.

Citizens' obligations to conserve the environment are further emphasized by judicial interpretations of constitutional duties. The Patna High Court upheld the obligation of every citizen under Article 51A(g) to maintain environmental preservation, including the appropriate operation of industrial operations, in the case of Sitaram Chapparia v. State of Bihar[8]. This emphasizes how environmental care and constitutional obligations go hand in hand.

Therefore, one important piece of legislation that India has used to combat air pollution and advance environmental protection is the Air (Prevention and Control) Act of 1986. The Act aims to lessen the harmful effects of air pollution on the environment and public health through its provisions, means of enforcement, and judicial interpretations. The significance of both individual and group effort in protecting India's natural legacy for future generations is further highlighted by constitutional provisions that place a strong emphasis on environmental responsibility.

Air Quality in Delhi

The Delhi National Capital Region (NCR) is more polluted than other large cities, making it one of the world's most highly polluted metropolitan centers. The public's health is being threatened by the frightening pollution rates; an estimated 1.5 million people might die as a result each year. According to studies carried out by India's Ministry of Earth Sciences, car emissions were the main cause of the roughly 41% of PM 2.5 pollution that was found in Delhi's air in October 2018[9].

Delhi's Air Quality Index (AQI) is generally reasonable from January to September, then progressively bad from October to December. One of the contributing elements during Diwali celebrations is the frequent use of firecrackers. The Supreme Court issued stringent timing limitations, outlawing the use of firecrackers between 10 p.m. and 6 a.m. in response to this environmental concern. This regulation action seeks to strike a balance between the need to protect public health and reduce air pollution and the enjoyment of cultural festivities by the general public[10].

Right to Life and Right to Clean and Healthy Environment

The right to life and personal liberty are guaranteed by Article 21 of the Indian Constitution. Judicial interpretations have established that Article 21 includes the right to live in a clean and healthy environment, even if it does not expressly give such right. The judiciary has emphasized the inextricable connection between environmental preservation and the basic rights to life and personal liberty guaranteed by Article 21 in a number of significant rulings. The judiciary has used Article 21 to issue decisions that protect the environment and guarantee public health in the effort to save life and advance environmental purity. Environmental law now follows the "Polluter Pays Principle" as a guiding concept.

According to this theory, the people who pollute the environment also have to pay for the harm they do. In essence, those who pollute must make up for the damage they cause to the environment. This strategy has worked well to hold polluters accountable for their activities and to encourage good environmental management.

In addition, the Supreme Court has upheld the notion that environmental pollution is a civil wrong, meaning that polluters are subject to tort law responsibility. Polluters must pay exemplary damages as a deterrence and are held accountable for the harm they do to the environment and society. This not only makes up for the losses suffered but also establishes a standard for responsible behavior and discourages further damage to the environment.

Therefore, The recognition of the right to a clean environment as an essential element of the basic right to life and personal liberty has been made possible by judicial interpretations of Article 21. Through the implementation of concepts like the Polluter Pays Principle and the imposition of liability on polluters, the legal system has played a role in advancing environmental conservation and the fulfillment of citizens' constitutional rights.

The importance of environmental stewardship in India's development process cannot be emphasized. Even if development is clearly the result of diligent work, it is critical that people understand how crucial it is to protect a clean and environmentally friendly environment. But reaching this objective would not be easy, especially considering how big and complicated India's growth path is. Achieving economic progress and maintaining environmental sustainability are essential for any nation to become developed, and all citizens must share this commitment.

Article 51A(g) and Article 48A of the Indian Constitution include constitutional provisions that are essential to this commitment. Every person has an obligation to preserve and enhance the natural environment, which includes lakes, rivers, forests, and animals, according to Article 51A(g). In a similar vein, Article 48A gives the state instructions to work toward enhancing and protecting the environment, as well as preserving forests and animals. The aforementioned constitutional requirements emphasize the fundamental connection between the protection of the environment and the joint obligation of the state and its inhabitants.

Human undertakings that disobey the fundamental laws of nature are condemned to failure and calamity, as Karl Marx rightly recognized. This is especially true given India's growth trajectory, where ignoring environmental issues might have disastrous results. Environmental deterioration threatens not only human health and welfare but also the fundamentals of sustainable development.

Delhi, in fact, is a sobering reminder of how urgently environmental deterioration has to be addressed. Delhi, one of the most polluted cities in the world, is seeing an alarming decline in air quality. Asthma, lung infections, and other chronic illnesses are only a few of the many chronic diseases that are exacerbated by the widespread pollution, which presents serious hazards to public health. Data suggest that pollution in Delhi might kill around 1.5 million people a year, which is a startling figure that highlights the need for immediate action.

The government must act decisively and cooperatively to address environmental deterioration in view of these grave truths. This means putting strict regulations in place to stop pollution and safeguard the environment. Strong enforcement measures must also be in place to hold individuals responsible for environmental harm accountable. People and organizations found guilty of damaging the environment or taking use of natural resources for their own benefit should face severe sanctions.

It is imperative to establish a culture of environmental stewardship and accountability by implementing punitive actions and setting an example. The government may convey to the public the seriousness of environmental crimes by making offenders responsible for their deeds. Punitive actions also have the deterrent effect of keeping people from taking actions that damage the environment or deplete natural resources. Hence, India's development strategy has to be based on a strong commitment to environmental sustainability.

Upholding the constitutional duties to preserve and enhance the natural environment is a duty owed by every person. Through the adoption of responsible policies and proactive efforts to protect the environment, India can steer towards sustainable growth and provide a more promising future for future generations.
