Nature and Definition of Environmental Law



Meaning of Environmental Law


Environmental Law refers to a comprehensive body of legal rules, regulations, and principles designed to regulate the interaction between humans and the natural environment. These laws aim to manage the impact of human activities on air, water, land, flora, fauna, and ecosystems.

A body of laws regulating human interaction with the environment

Environmental law governs the use, preservation, and restoration of the environment by imposing obligations on individuals, corporations, and governments. These laws regulate pollution, waste management, environmental impact assessment (EIA), and ecological conservation.

Interdisciplinary nature

Environmental law is inherently interdisciplinary, drawing from legal studies, environmental science, economics, public health, international relations, and technology. It integrates principles from various disciplines to ensure a holistic approach to environmental protection and sustainable management.



Scope of Environmental Law


Pollution control

Environmental laws aim to monitor, control, and reduce pollution through regulatory frameworks. For example, the Air (Prevention and Control of Pollution) Act, 1981 and the Water (Prevention and Control of Pollution) Act, 1974 set emission standards and penalties for violators.

Resource management

These laws ensure the sustainable management of natural resources like forests, minerals, water bodies, and wildlife. Legal instruments like the Forest Conservation Act, 1980 and Wildlife Protection Act, 1972 play key roles.

Biodiversity protection

The conservation of biological diversity is a core focus. Environmental law seeks to preserve species, habitats, and ecological balance through protective zones, bans on hunting, and international conventions like the Convention on Biological Diversity (CBD).

Climate change

Climate change law focuses on mitigating greenhouse gas emissions and adapting to its effects. This includes India's commitments under the Paris Agreement and legislation supporting renewable energy, emission reductions, and carbon trading frameworks.

Sustainable development

Environmental law supports the principle of sustainable development—meeting the needs of the present without compromising future generations. It emphasizes balance between economic growth and environmental protection.



Objectives of Environmental Law


Prevention and control of pollution

The primary goal is to prevent, minimize, and eliminate pollution of air, water, and land. This includes standards for industries, vehicles, and waste treatment under various pollution control statutes.

Conservation of natural resources

Environmental law aims to conserve finite natural resources such as forests, minerals, wetlands, and water, by regulating their use and encouraging replenishment and protection.

Protection of human health and environment

A key objective is to safeguard human health by regulating exposure to toxic substances, hazardous wastes, and radiation. This also includes preventing ecological degradation that affects food security and livelihoods.

Promotion of sustainable development

Environmental law seeks to integrate environmental considerations into development planning, ensuring long-term ecological balance and intergenerational equity. Principles like precautionary principle, polluter pays principle, and intergenerational equity are integral to this goal.
