Climate change is one of the most critical environmental challenges facing the world today. It refers to long-term and significant changes in global weather patterns, primarily caused by human activities and natural variability. The Intergovernmental Panel on Climate Change (IPCC) defines climate change as alterations in the Earth’s climate due to human-induced activities, such as excessive greenhouse gas (GHG) emissions, which disrupt natural atmospheric composition.

The phenomenon of climate change is often referred to as a “global problem” because its effects are not confined to specific regions or nations. Rising temperatures, melting glaciers, and extreme weather patterns impact the entire planet, making it a shared concern for humanity. This interconnectedness has given rise to the term Global Commons, which refers to shared resources including the atmosphere, the high seas, Antarctica, and outer space. Susan J. Buck’s The Global Commons: An Introduction (1998) emphasized the collective responsibility to preserve these resources for global well-being.

A related concept, The Tragedy of the Commons, was introduced by Garrett Hardin in 1968. It describes how shared resources are overused and depleted when individuals prioritize personal gain over collective interests. Similarly, Common Heritage of Mankind, a principle proposed by Arvid Pardo in 1967, advocates for equitable and sustainable management of natural resources, emphasizing that they belong not only to the present generation but also to future ones.

Climate change manifests through clear indicators such as ozone layer depletion, rising sea levels, melting glaciers, and acid rain. These phenomena disrupt ecosystems, endanger biodiversity, and threaten human livelihoods. A key driver of climate change is global warming, the gradual increase in the Earth’s surface and atmospheric temperatures. This is caused by GHGs like carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and chlorofluorocarbons (CFCs), which trap heat in the atmosphere and prevent it from escaping back into space.

Efforts to combat climate change have led to international agreements like the United Nations Framework Convention on Climate Change (UNFCCC), which came into force in 1994, and the Montreal Protocol (1987), aimed at phasing out ozone-depleting substances. The Kyoto Protocol (1997) and subsequent summits like the Copenhagen Summit (2009) have also sought to address global emissions and climate impacts.

Addressing climate change requires global cooperation, sustainable practices, and adherence to these international frameworks. It is a pressing challenge that demands immediate attention to safeguard the future of the planet and its inhabitants.

How Do Human Activities Contribute to Climate Change?

Human activities significantly contribute to climate change by releasing four main greenhouse gases: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and halocarbons. These gases accumulate in the atmosphere and have drastically increased during the industrial era, now called the Anthropocene, a term coined by Eugene F. Stoermer and popularized by Paul Crutzen. This era marks the profound influence of human actions on Earth’s systems, affecting its climate and ecosystems.

Key Greenhouse Gas Contributions:

1. Carbon Dioxide (CO2):
   1. Released through fossil fuel use in transportation, heating/cooling, cement manufacturing, and deforestation, which also reduces carbon uptake by plants.
   1. CO2 is naturally emitted during processes like plant decay but is amplified by human activities.
2. Methane (CH4):
   1. Emitted from agriculture (e.g., livestock), natural gas distribution, and landfills.
   1. Naturally released in wetlands but significantly increased by human actions.
3. Nitrous Oxide (N2O):
   1. Results from fertilizer use, fossil fuel combustion, and industrial activities.
   1. Also produced naturally in soils and oceans.
4. Halocarbons:
   1. Includes chlorofluorocarbons (CFCs) used in refrigeration and industry, now regulated due to their role in stratospheric ozone depletion.

Other Climate Influencers:

• Ozone:
  • Tropospheric ozone has increased due to emissions like carbon monoxide and nitrogen oxides, while stratospheric ozone has been depleted by halocarbons, causing phenomena like the ozone hole over Antarctica.
• Water Vapour:
  • Although not directly influenced by human actions, a warmer climate increases water vapor, which in turn amplifies the greenhouse effect. Methane also indirectly contributes to water vapor through its chemical breakdown in the stratosphere.
• Aerosols:
  • These tiny particles, from sources like fossil fuel combustion, biomass burning, and industrial dust, affect climate by scattering sunlight and influencing cloud formation. Aerosols include both natural sources (e.g., sea salt, volcanic dust) and human-induced pollutants.

Global Change and Climate Change

Global change refers to transformations on a worldwide scale, such as increased atmospheric carbon dioxide or global biodiversity loss. It includes human-driven impacts like urbanization, industrialization, and resource exploitation. Historically, global change was driven by natural factors like solar output, tectonic activity, volcanic eruptions, and Earth’s orbital variations. However, the modern era, marked by significant human influence, is referred to as the Anthropocene, a term popularized by chemist Paul Crutzen. This era is characterized by widespread environmental changes resulting from human activities over just 250 years, including pollution, deforestation, and increased demand for energy and goods.

Global change encompasses various elements, such as population growth, urbanization, land use, ocean circulation, atmospheric changes, and sea-level rise. According to the Amsterdam Declaration (2001), human activities are altering essential planetary systems, jeopardizing resources like food, water, and clean air. The declaration emphasized that these changes threaten human well-being and require urgent global action.

Climate Change: A Central Concern

Climate change is a key aspect of global change, driven by rising greenhouse gas emissions. Since 1850, global temperatures have risen by 1.2°C due to human activities, with projections of an additional 2–3°C increase within the next 50 years if emissions persist. Eleven of the twelve hottest years occurred between 1995 and 2006, underscoring the rapidity of warming.

Key consequences include:

1. Rising Sea Levels: Ice sheets in Greenland and Antarctica are melting, adding water to oceans. Coastal megacities like Mumbai and Boston, as well as island nations, are at risk of submersion.
2. Extreme Weather: More intense storms, prolonged droughts, and erratic rainfall patterns are jeopardizing agriculture and water supplies, particularly in developing regions.
3. Biodiversity Loss: Rapid warming outpaces many species’ ability to adapt. With 3°C warming, 20–30% of land species face extinction. Coral reefs are suffering from bleaching and acidification, while polar ecosystems are being decimated.
4. Human Health Impacts: Diseases like malaria and dengue are spreading to new areas due to warming. Developing countries, with limited healthcare resources, are particularly vulnerable to these impacts.

Climate Change and Human Development

Climate change threatens global efforts to combat poverty and improve living standards. According to the Human Development Report (2007/08), climate change endangers progress in reducing poverty, enhancing education, and improving health outcomes.

Key risks include:

• Agricultural Impact: Reduced rainfall and rising temperatures could diminish crop yields, increasing malnutrition and hunger, particularly in Sub-Saharan Africa, South Asia, and Latin America.
• Water Scarcity: Changes in glacier melt and rainfall patterns could leave 1.8 billion people in water-scarce environments by 2080, impacting regions like South Asia, Central Asia, and the Andes.
• Displacement and Disasters: Sea-level rise and intense tropical storms could displace millions, affecting countries like Bangladesh, Egypt, and Vietnam, as well as small island states.
• Ecosystem Disruption: Rapid climate shifts threaten ecosystems, with oceans becoming more acidic and coral reefs and ice-based habitats collapsing.
• Health Crises: Expanded ranges for diseases like malaria and dengue could expose hundreds of millions more people, compounding existing healthcare challenges.

These impacts, acting together, threaten the sustainability of human and ecological systems. Combating climate change is not only an environmental necessity but also a fundamental challenge to sustaining human development and global equity.

Climate Change Debates: Kyoto Protocol and Copenhagen Summit

The global response to climate change has been shaped by several pivotal international efforts, beginning with the Brundtland Report (1987), Rio Earth Summit (1992) and continuing through agreements like the Kyoto Protocol (1997) and the Copenhagen Summit (2009). These milestones reflect a concerted global effort to tackle climate change, though both the Kyoto Protocol and the Copenhagen Summit faced significant challenges and criticisms regarding their effectiveness.

The Brundtland Report: Foundation of Sustainable Development

The Brundtland Report, officially titled Our Common Future, was published in 1987 by the United Nations World Commission on Environment and Development (WCED). It is widely recognized as a foundational text in shaping modern global environmental policy.

Definition of Sustainable Development
The report introduced a landmark definition of sustainable development, describing it as development that fulfills present needs without limiting the ability of future generations to meet their own.

Key Pillars of Sustainability
The report emphasized that sustainability is achieved through the integration of three interrelated pillars:

• Economic Growth: Promoting economic progress that is robust while remaining socially responsible and environmentally sustainable.
• Environmental Protection: Preserving the Earth’s vital life-support systems, including air, water, and soil.
• Social Equity: Reducing global poverty and ensuring that all people have access to basic needs and opportunities.

Historical Significance and Legacy

• The Commission: Led by Gro Harlem Brundtland, former Prime Minister of Norway, and composed of experts from 21 countries.
• Global Impact: The report reframed global discourse by highlighting the interdependence of economic development and environmental protection.
• Lasting Influence: It laid the foundation for major international initiatives such as the 1992 Rio Earth Summit, the Sustainable Development Goals (SDGs), and global agreements on climate change and biodiversity.

Rio Earth Summit (1992)

The Rio Earth Summit, officially called the United Nations Conference on Environment and Development (UNCED), was a major global conference held in Rio de Janeiro, Brazil, from 3 to 14 June 1992. It brought together representatives and leaders from 178 countries to discuss the increasing tension between economic growth and the need to protect the environment.

Major Outcomes and Agreements

The summit resulted in several important agreements and documents that continue to influence international environmental policy:

• Agenda 21: A detailed, voluntary action plan designed to promote sustainable development in the twenty-first century.
  
• Rio Declaration on Environment and Development: A set of 27 principles outlining the duties and rights of nations in pursuing sustainable development.
  
• The Rio Conventions: Three key international treaties were opened for signature to tackle major global environmental challenges:
  
  • United Nations Framework Convention on Climate Change (UNFCCC), which aims to stabilize greenhouse gas concentrations and address climate change.
    
  • Convention on Biological Diversity (CBD), focused on conserving biological diversity and ensuring fair sharing of genetic resources.
    
  • United Nations Convention to Combat Desertification (UNCCD), which seeks to combat desertification and reduce the impacts of drought and was formally recommended at the summit.
    
• Forest Principles: A non-legally binding set of guidelines for the conservation, management, and sustainable use of all types of forests.
  

Long-Term Significance

The Rio Earth Summit played a crucial role in spreading the idea of sustainable development, stressing that economic progress and environmental protection must go hand in hand. It led to the creation of the Commission on Sustainable Development to track global progress on sustainability goals. The summit also introduced and strengthened the principle of Common But Differentiated Responsibilities (CBDR), recognizing that while all countries are responsible for environmental protection, developed nations have a greater historical responsibility for environmental degradation.

The Kyoto Protocol (1997)

During the late twentieth century, scientists became increasingly concerned about climate change. Research showed that human activities, especially the burning of fossil fuels, were increasing the amount of greenhouse gases (GHGs) in the atmosphere. These gases trap heat and cause global warming, which can lead to rising sea levels, damage to ecosystems, and serious risks to human life. To respond to this problem, countries came together at the Rio Earth Summit in 1992 and adopted the United Nations Framework Convention on Climate Change (UNFCCC). The main goal of the UNFCCC was to stabilize greenhouse gas levels in the atmosphere so that human activities would not cause dangerous climate change. However, this agreement did not set legally binding limits on emissions.

Because the UNFCCC was not strong enough to force countries to reduce emissions, further discussions were held during the 1990s. These talks led to the adoption of the Kyoto Protocol on 11 December 1997 in Kyoto, Japan. The Kyoto Protocol became the first legally binding international agreement that focused directly on reducing greenhouse gas emissions. It placed legal responsibility on industrialized countries, as they had produced most greenhouse gases in the past.

Although the Kyoto Protocol was adopted in 1997, it did not become active right away. For the agreement to take effect, at least 55 countries representing 55% of greenhouse gas emissions from industrialized nations in 1990 had to ratify it. Due to political disagreements, this process took many years. As a result, the protocol entered into force on 16 February 2005. By November 2009, 187 countries had ratified the Kyoto Protocol, showing strong global support

One major problem for the Kyoto Protocol was the decision of the United States not to ratify it. Although the United States signed the agreement, it later withdrew from the ratification process. This was very important because in 1990, the United States was responsible for 36.1% of greenhouse gas emissions among industrialized countries. Its absence reduced the overall effectiveness of the agreement and raised concerns about fairness, since some countries had to cut emissions while others did not

Under the Kyoto Protocol, 37 industrialized countries, known as Annex I countries, were given legally binding targets. These countries agreed to reduce their combined greenhouse gas emissions by an average of 5.2% below 1990 levels during the first commitment period from 2008 to 2012. The protocol covered six greenhouse gases: carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), sulphur hexafluoride (SF₆), hydrofluorocarbons (HFCs), and perfluorocarbons (PFCs). However, emissions from international aviation and shipping were not included in the binding targets. Some industrial gases, such as chlorofluorocarbons (CFCs), were already controlled under the 1987 Montreal Protocol, not the Kyoto Protocol

Even though the Kyoto Protocol was legally binding, many experts questioned whether it could significantly reduce global warming. Even if all participating countries met their targets, the total reduction in global emissions would be small compared to the continued growth of emissions worldwide. One important reason is the long life of carbon dioxide in the atmosphere, which can last for up to a century.

Scientists also explained that the Earth was already committed to more warming because of past emissions. Even if all fuel-burning machines were turned off immediately, global temperatures would still rise by about 0.5°C over the following decades. This would happen because the oceans have absorbed large amounts of heat over time and slowly release it back into the atmosphere. This situation is often described as “warming already in the system”

In conclusion, the Kyoto Protocol was an important step in global efforts to fight climate change. It was the first agreement to make emission reduction targets legally binding. However, its impact was limited because of relatively small reduction targets, the exclusion of some sectors, and the refusal of major emitters like the United States to participate. Even so, the Kyoto Protocol played a key role in shaping future international climate agreements and showed the need for stronger and longer-term global action to reduce greenhouse gas emissions.

Copenhagen Summit (2009)

The Copenhagen Summit, formally known as the United Nations Climate Change Conference 2009, was held in Copenhagen, Denmark, from December 7–18, 2009. It was expected to build on the previous frameworks, such as the Bali Road Map, and set a new direction for international climate change mitigation efforts beyond 2012. The aim was to secure a legally binding agreement that would address the growing climate crisis and establish firm emission reduction targets for all nations. However, the summit ended in disappointment for many environmental advocates and vulnerable nations, primarily due to the lack of a legally binding agreement.

During the summit, the Copenhagen Accord was drafted by key nations—the United States, China, India, Brazil, and South Africa—on December 18, 2009. The document was seen as a “meaningful agreement” by the United States government but was not adopted by the full plenary of all participating countries. It was only “taken note of” by the official meeting, meaning it was not legally binding. The accord acknowledged that climate change is one of the greatest challenges of our time and called for global efforts to limit the rise in global temperatures to below 2°C compared to pre-industrial levels. However, it did not set firm emissions reduction targets, nor did it provide a clear legal framework for global emissions reductions, making the accord fall short of the expectations set by many environmental groups and the world’s most vulnerable countries.

One of the most contentious issues was the lack of legally binding commitments for reducing CO₂ emissions, which many critics argued would be necessary to achieve the goal of keeping the global temperature increase below 2°C. Although the Copenhagen Accord recognized the importance of this target, it did not include specific commitments or mechanisms to enforce emissions reductions. Additionally, countries most vulnerable to the impacts of climate change—such as small island states—felt that the accord did not meet their needs or expectations. Instead, the document outlined a financial commitment of US$30 billion for developing countries over the next three years, with pledges to increase this to US$100 billion per year by 2020, to help these nations adapt to climate change. This proposal was a response to the needs of poorer nations that had been advocating for financial support to mitigate and adapt to the impacts of climate change.

Despite widespread hopes that the Copenhagen Summit would result in a legally binding treaty, the event was marked by negotiating deadlock and disagreements. The Copenhagen Accord, as a result, was not enforceable and did not include binding commitments on key issues such as emissions reductions and the timeline for achieving specific climate goals. Early in 2010, several countries, including India and various small island nations, expressed dissatisfaction with the accord, arguing that it failed to adequately address the scale of the climate crisis. Indian journalist Praful Bidwai criticized both developed and some developing countries for their role in shaping the outcome, labeling the Copenhagen Accord as an “illegitimate” and “ill-conceived” deal. He argued that the accord was a collusion between a handful of countries that would allow the world’s biggest emitters to continue their high-consumption lifestyles at the expense of poorer nations.

In the aftermath, the Copenhagen Accord called for countries to submit their national emissions reduction targets by the end of January 2010, and laid the groundwork for further discussions at the 2010 UN Climate Change Conference in Mexico. By early February 2010, 67 countries had registered their targets, but the lack of progress on a legally binding treaty and the challenges of reaching a comprehensive international agreement left many observers questioning the future role of the UNFCCC in driving meaningful global climate action.

Minamata Convention on Mercury

The Minamata Convention on Mercury is a global environmental agreement designed to reduce the harmful effects of mercury on human health and the environment. Its formulation progressed through several key stages: the treaty text was finalized in Geneva on 19 January 2013, officially adopted and opened for signature on 10 October 2013 at a diplomatic conference in Kumamoto and Minamata, Japan, and became legally binding on 16 August 2017 after ratification by fifty countries. Shortly thereafter, the first Conference of the Parties was held in September 2017 in Geneva, Switzerland.

The convention is named after the Japanese city of Minamata, which suffered a serious environmental disaster beginning in 1956. Industrial discharge containing methylmercury polluted Minamata Bay, contaminating seafood and causing severe mercury poisoning among residents who relied on fish for food. This tragedy, later known as Minamata disease, highlighted the global risks posed by mercury pollution and led to international action.

The central objective of the convention is to protect human health and the environment from mercury released by human activities. To meet this goal, the treaty bans the establishment of new mercury mines and requires the gradual phase-out of existing ones, restricts the use of mercury in products and industrial processes, regulates artisanal and small-scale gold mining, and mandates controls on mercury emissions from coal-fired power plants and industrial sources.

Global Environment Facility (GEF)

The Global Environment Facility (GEF) is the world’s largest multilateral funding mechanism dedicated to addressing global environmental problems. It was established in 1991 to support developing countries and countries with economies in transition by providing grants and concessional financing for projects that generate global environmental benefits while also promoting sustainable development at the national and local levels.

The GEF was initially launched as a pilot program within the World Bank, developed in partnership with the United Nations Development Programme (UNDP) and the United Nations Environment Programme (UNEP). After the 1992 Rio Earth Summit, it was restructured in 1994 and became a permanent and independent institution. Although independent, the World Bank continues to act as the Trustee, managing the GEF Trust Fund and overseeing its financial administration.

The core mandate of the GEF is to assist countries in meeting their obligations under major international environmental agreements. It serves as the official financial mechanism for five key conventions: the Convention on Biological Diversity, the UN Framework Convention on Climate Change, the UN Convention to Combat Desertification, the Stockholm Convention on Persistent Organic Pollutants, and the Minamata Convention on Mercury. Through this role, the GEF links global environmental priorities with national development needs.

GEF funding is organized around six focal areas: biodiversity conservation, climate change mitigation and adaptation, land degradation, international waters, chemicals and waste management, and protection of the ozone layer. Projects supported under these areas focus on ecosystem protection, clean energy transition, sustainable land use, pollution reduction, and cooperative management of shared natural resources.

The GEF operates through a broad global partnership that includes 186 member countries, international institutions, civil society organizations, and the private sector. Its governance structure consists of the GEF Assembly, which includes all member countries; the GEF Council, the main decision-making body; and the GEF Secretariat, headquartered in Washington, D.C., which manages day-to-day operations and coordination.

Funding for the GEF is provided by donor countries and replenished every four years. The current replenishment cycle, GEF-8 (2022–2026), has secured a record commitment of USD 5.33 billion, highlighting strong international support for global environmental action.

India plays an important role in the GEF both as a donor and a beneficiary. It has received more than USD 1 billion in GEF assistance for over 100 projects focused on biodiversity conservation, climate change action, and sustainable land management, contributing significantly to national environmental goals.

Overall, the Global Environment Facility is a cornerstone of international environmental finance. By supporting innovative projects, strengthening global cooperation, and aligning environmental protection with sustainable development, the GEF plays a critical role in addressing some of the world’s most pressing environmental challenges.

National Action Plan on Climate Change (NAPCC)

India’s National Action Plan on Climate Change (NAPCC) was launched on 30th June 2008 to address the challenges posed by climate change while promoting sustainable growth. The NAPCC advocates a two-pronged strategy: the first is to develop adaptation measures to deal with the impacts of climate change, and the second is to enhance ecological sustainability in the country’s development trajectory. The NAPCC aims to help India maintain its rapid economic growth, protect vulnerable sections of society, and achieve national development goals, all while addressing climate change.

The NAPCC outlines eight key missions, with 24 specific initiatives to mitigate the effects of climate change. These missions focus on several critical sectors, including energy generation, transport, renewable energy, disaster management, and capacity building. Despite these proposed actions, the NAPCC lacks clear targets and detailed action plans for implementation. One of the significant challenges is ensuring the effective implementation of these missions at the grassroots level, where diverse regional issues and challenges exist.

The eight missions proposed by the NAPCC are:

1. National Solar Mission: Aims to promote the use of solar energy as a clean alternative to fossil fuels.
2. National Mission for Enhanced Energy Efficiency: Focuses on improving energy efficiency across various sectors to reduce energy consumption and greenhouse gas emissions.
3. National Mission on Sustainable Habitat: Encourages sustainable urban development, focusing on reducing energy consumption and improving waste management in cities.
4. National Water Mission: Works towards water conservation and sustainable management of water resources.
5. National Mission for Sustaining the Himalayan Ecosystem: Aims to protect the fragile Himalayan ecosystem and ensure its sustainability.
6. National Mission for a “Green India”: Focuses on increasing forest cover and enhancing carbon sequestration through afforestation and reforestation.
7. National Mission for Sustainable Agriculture: Promotes sustainable agricultural practices that conserve resources and increase resilience to climate change.
8. National Mission on Strategic Knowledge for Climate Change: Focuses on building the scientific knowledge base and increasing awareness about climate change and its impacts.

These missions are critical for mitigating climate change, but their success largely depends on their effective implementation across different regions of India. Given the country’s geographical and ecological diversity, the impact of climate change will vary from region to region. Therefore, a one-size-fits-all approach at the national level may not be sufficient to address the specific challenges faced by different states.

State-Level Action Plans on Climate Change

Recognizing the diverse challenges posed by climate change across different regions, the Government of India has encouraged states to create state-level action plans on climate change. In August 2009, the Prime Minister urged states to develop their own plans aligned with the NAPCC’s strategy. These plans aim to help local communities and ecosystems adapt to climate change and to complement the broader goals of the NAPCC.

Several states have already initiated efforts to develop these action plans. For example, the Government of Himachal Pradesh and Karnataka sought technical assistance and funding from the World Bank to implement their climate change action plans. Delhi launched its action plan in November 2009, detailing various activities and initiatives to mitigate climate change impacts. In Kerala, a steering committee was set up to oversee the preparation of the state’s action plan. Similarly, Gujarat took proactive measures by establishing a dedicated department for climate change, while Orissa developed a draft action plan that was circulated for feedback.

While these steps indicate positive movement at the state level, much work remains to be done. Many of these plans, though created, have yet to lead to significant action on the ground. The implementation of these plans, particularly at the grassroots level, remains a major challenge, as states need both financial resources and technical support to turn these action plans into tangible outcomes.

Overall, while the NAPCC lays out a comprehensive strategy for addressing climate change at the national level, its success will depend heavily on the ability of both the central government and the individual states to implement and monitor these initiatives effectively. The participation of all stakeholders—government, businesses, and communities—is essential to ensure the long-term success of India’s climate change adaptation and mitigation efforts.

Environmental Laws in India

Environmental laws in India constitute a comprehensive legal framework designed to protect the environment, conserve natural resources, and ensure sustainable development. These laws are deeply rooted in constitutional mandates, shaped by international environmental commitments, and strengthened through judicial interpretation. Over time, India has developed a multi-layered system of environmental governance addressing wildlife protection, pollution control, forest conservation, biodiversity protection, energy efficiency, and environmental justice.

Constitutional Provisions Relating to Environment

Environmental protection in India derives its legitimacy from the Constitution. Article 48A, inserted by the Forty-Second Constitutional Amendment Act, 1976, directs the State to protect and improve the environment and safeguard forests and wildlife. Although it forms part of the Directive Principles of State Policy and is not enforceable by courts, it has guided the enactment of several environmental laws. Article 51A(g) imposes a fundamental duty on every citizen to protect and improve the natural environment, including forests, lakes, rivers, and wildlife, and to show compassion for living creatures. Judicial interpretation of Article 21 has further expanded the scope of environmental protection by recognizing the right to a clean and healthy environment as an integral part of the right to life.

Wildlife (Protection) Act, 1972

The Wildlife (Protection) Act, 1972 was enacted to provide legal protection to wild animals, birds, and plants and to ensure ecological and environmental security. The Act applies across India and regulates hunting, trade, and commerce in wildlife and wildlife products. It introduces a system of schedules that classify species according to the level of protection required, with the highest degree of protection given to endangered species. The Act also provides for the establishment of protected areas such as national parks and wildlife sanctuaries and creates statutory bodies including the National Board for Wildlife, Central Zoo Authority, Wildlife Crime Control Bureau, and National Tiger Conservation Authority to strengthen wildlife conservation and enforcement mechanisms.

Water (Prevention and Control of Pollution) Act, 1974

The Water (Prevention and Control of Pollution) Act, 1974 was enacted to prevent and control water pollution and to maintain or restore the wholesomeness of water bodies. This Act led to the establishment of the Central Pollution Control Board and State Pollution Control Boards, which are responsible for setting effluent standards, monitoring water quality, and regulating the discharge of pollutants into rivers, lakes, streams, and groundwater. The Act empowers pollution control boards to grant or refuse consent to industries for discharging effluents and to take legal action against polluters.

Forest (Conservation) Act, 1980

The Forest (Conservation) Act, 1980 was introduced to curb deforestation and regulate the diversion of forest land for non-forest purposes. The Act mandates prior approval of the central government for dereservation of forests or diversion of forest land for activities such as mining, infrastructure development, and industrial projects. By centralizing decision-making authority, the Act significantly restricted the unchecked exploitation of forest resources and strengthened forest conservation across the country.

Air (Prevention and Control of Pollution) Act, 1981

The Air (Prevention and Control of Pollution) Act, 1981 was enacted to prevent, control, and abate air pollution. Under this Act, the Central and State Pollution Control Boards are responsible for implementing air quality standards and regulating emissions from industries, vehicles, and power plants. State governments are empowered to declare air pollution control areas where stricter emission norms apply. The Act regulates the emission of harmful pollutants such as particulate matter, sulfur dioxide, nitrogen oxides, carbon monoxide, and volatile organic compounds.

Environment (Protection) Act, 1986

The Environment (Protection) Act, 1986 is the umbrella legislation for environmental protection in India. It was enacted in the aftermath of the Bhopal Gas Tragedy of 1984 and under Article 253 of the Constitution to give effect to international environmental obligations. The Act grants wide powers to the central government to set environmental standards, regulate industrial activities, manage hazardous substances, and issue binding directions including the closure or restriction of polluting industries. Several important rules and notifications, such as Environmental Impact Assessment requirements and eco-sensitive zone notifications, have been issued under this Act.

Public Liability Insurance Act, 1991

The Public Liability Insurance Act, 1991 was enacted to provide immediate relief to victims of accidents involving hazardous substances. The Act mandates that industries handling hazardous materials obtain insurance policies to cover potential liabilities. It operates on the principle of no-fault liability, ensuring prompt compensation without requiring victims to prove negligence.

Ozone Depleting Substances (Regulation and Control) Rules, 2000

The Ozone Depleting Substances Rules, 2000 were framed under the Environment (Protection) Act to fulfill India’s obligations under the Montreal Protocol. These rules regulate the production, consumption, import, and export of ozone-depleting substances such as chlorofluorocarbons and halons and prescribe a phased elimination schedule. Limited exemptions are allowed for essential medical purposes.

Energy Conservation Act, 2001

The Energy Conservation Act, 2001 was enacted to promote efficient use of energy and reduce wastage. The Act provides for the formulation of energy consumption standards for appliances, equipment, and buildings and led to the establishment of the Bureau of Energy Efficiency as a statutory body. The Energy Conservation (Amendment) Act, 2022 further strengthened the framework by introducing a carbon credit trading scheme and mandating minimum non-fossil energy consumption for designated consumers.

Biological Diversity Act, 2002

The Biological Diversity Act, 2002 was enacted to conserve biological diversity, promote sustainable use of biological resources, and ensure fair and equitable sharing of benefits arising from their use. The Act aims to prevent biopiracy and protect traditional knowledge. It establishes a three-tier institutional mechanism consisting of the National Biodiversity Authority, State Biodiversity Boards, and Biodiversity Management Committees. The Biological Diversity (Amendment) Act, 2023 simplified compliance requirements and encouraged domestic research and innovation.

Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006

The Forest Rights Act, 2006 was enacted to recognize and vest forest rights in forest-dwelling Scheduled Tribes and other traditional forest dwellers who have been residing in forests for generations. The Act addresses historical injustices by recognizing individual and community rights over forest land and resources while assigning responsibilities for sustainable forest management and biodiversity conservation.

National Green Tribunal Act, 2010

The National Green Tribunal Act, 2010 established a specialized judicial body for the expeditious disposal of environmental cases. The Tribunal has original jurisdiction over substantial environmental questions arising under key environmental laws and is mandated to dispose of cases within six months. It provides an effective mechanism for environmental justice by combining legal and scientific expertise.

Compensatory Afforestation Fund Act, 2016

The Compensatory Afforestation Fund Act, 2016 was enacted to manage funds collected for compensatory afforestation when forest land is diverted for non-forest purposes. The Act provides a statutory framework for fund distribution between the Centre and States and specifies permissible uses such as afforestation, wildlife management, and mitigation of human-wildlife conflict.

Recent Amendments and Rules

In recent years, India’s environmental governance framework has undergone significant changes aimed at balancing environmental protection with economic development, ease of compliance, and climate commitments. These amendments and rules reflect a shift from purely punitive regulation towards transparency, accountability, and sustainable management of resources, while still retaining environmental safeguards.

Wildlife (Protection) Amendment Act, 2022

The Wildlife (Protection) Amendment Act, 2022 was enacted to modernize and strengthen the Wildlife (Protection) Act, 1972 in line with India’s international obligations and emerging conservation challenges. One of the most important changes introduced by this amendment was the rationalization of species schedules. Earlier, the Act contained six schedules that were often criticized for being complex and outdated. The amendment reduced and reorganized these schedules to improve clarity and enforcement efficiency. The highest level of protection continues to be accorded to endangered species, while the revised structure aligns Indian wildlife protection laws with global conservation standards.

The amendment also strengthened provisions relating to the regulation of wildlife trade, particularly to meet India’s obligations under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). It introduced stricter controls on the possession, transport, and trade of scheduled wildlife species and their derivatives. Additionally, the amendment expanded the scope of penalties for wildlife offences, thereby enhancing deterrence against poaching and illegal trade. Overall, the Act marked a shift towards a more internationally harmonized and enforcement-oriented wildlife conservation regime.

Jan Vishwas (Amendment of Provisions) Act, 2023

The Jan Vishwas Act, 2023 represents a significant reform in India’s regulatory approach, including environmental governance. The primary objective of this Act was to improve ease of doing business and reduce the burden of criminal liability for minor and procedural offences under various laws, including environmental legislations framed under the Environment (Protection) Act, 1986. The Act replaced imprisonment provisions for minor violations with monetary penalties, thereby decriminalizing technical and non-serious environmental offences.

In the environmental context, this amendment sought to distinguish between serious environmental harm and minor compliance failures. While grave violations that cause environmental damage continue to attract stringent penalties, procedural lapses such as delays in filings or minor reporting failures are now subject to financial penalties instead of criminal prosecution. The Act reflects a policy shift towards trust-based governance, encouraging voluntary compliance while retaining the State’s power to act firmly against major polluters.

Biological Diversity (Amendment) Act, 2023

The Biological Diversity (Amendment) Act, 2023 was enacted to address concerns related to regulatory complexity and compliance burden under the Biological Diversity Act, 2002. This amendment came into force on April 1, 2024, and aimed to simplify procedures while continuing to protect biodiversity and traditional knowledge. One of the key changes introduced by the amendment was the relaxation of compliance requirements for domestic researchers, startups, and industries that use biological resources, particularly those involved in traditional medicine and agricultural research.

The amendment sought to encourage innovation, research, and commercialization of biological resources within India by reducing approval-related delays. At the same time, it retained safeguards against biopiracy and ensured that benefit-sharing mechanisms remained intact for the protection of indigenous communities and local knowledge holders. Thus, the amendment attempted to strike a balance between biodiversity conservation and economic utilization of biological resources.

Environment Audit Rules, 2025

The Environment Audit Rules, 2025 represent a major step towards strengthening environmental compliance and transparency in India. Effective from August 2025, these rules mandate industries and specified establishments to conduct systematic environmental audits at regular intervals. The purpose of these audits is to assess compliance with environmental laws, emission standards, waste management rules, and consent conditions issued by regulatory authorities.

Under these rules, industries are required to document their environmental performance, identify areas of non-compliance, and implement corrective measures. The audit findings must be reported to designated authorities, thereby enhancing accountability and enabling better regulatory oversight. The introduction of mandatory environmental audits reflects a shift from reactive enforcement to preventive environmental management and is expected to improve corporate environmental responsibility.

End-of-Life Vehicles Rules, 2025

The End-of-Life Vehicles Rules, 2025 were notified to address the growing environmental and public health concerns associated with old and unfit vehicles. Effective from April 2025, these rules establish a regulatory framework for the scientific dismantling, recycling, and disposal of end-of-life vehicles. The rules aim to reduce air pollution, recover valuable materials such as metals and plastics, and prevent unsafe disposal practices.

The rules prescribe standards for authorized vehicle scrapping facilities and mandate environmentally sound recycling processes. They also support India’s circular economy goals by promoting resource recovery and reducing dependence on virgin raw materials. By regulating vehicle disposal, these rules contribute to cleaner air, improved waste management, and sustainable urban transport systems.

Overall Significance of Recent Amendments and Rules

Collectively, these recent amendments and rules indicate a clear evolution in India’s environmental governance approach. While earlier laws focused heavily on prohibition and punishment, recent reforms emphasize compliance facilitation, transparency, technological adaptation, and sustainable development. At the same time, core environmental objectives such as biodiversity conservation, wildlife protection, pollution control, and ecological sustainability remain central to the legal framework.

Conclusion

In conclusion, climate change represents an existential challenge requiring immediate and sustained global efforts. Its wide-reaching impacts on ecosystems, economies, and human livelihoods highlight the urgency for international collaboration and sustainable practices. While initiatives like the Kyoto Protocol and Copenhagen Summit laid foundations for addressing this crisis, their limitations underscore the need for more robust, enforceable commitments. A shift towards renewable energy, equitable resource management, and climate-resilient development is essential. By recognizing climate change as a shared responsibility, humanity can strive for a balanced future that protects the planet for current and future generations. The time to act is now.
