2-Minute Revision

Environmental laws and policies in India are anchored in constitutional provisions like Article 48A (State's duty) and Article 51A(g) (citizen's duty), with the judiciary interpreting Article 21 to include the Right to a Clean Environment.

The Environment (Protection) Act, 1986 (EPA), acts as the primary umbrella legislation, empowering the Central Government to set standards and regulate pollution. Specific acts address various domains: the Water Act, 1974, and Air Act, 1981, established the Central and State Pollution Control Boards (CPCB/SPCBs) for monitoring and enforcement.

Forest conservation is governed by the Forest (Conservation) Act, 1980 (FCA), while wildlife protection falls under the Wildlife (Protection) Act, 1972 (WPA). A significant institutional development is the National Green Tribunal (NGT), established in 2010, providing specialized and expeditious environmental justice, applying principles like 'Polluter Pays' and 'Precautionary Principle'.

The Environmental Impact Assessment (EIA) process is a crucial regulatory tool for developmental projects. Policy frameworks such as the National Environment Policy, 2006, and the National Action Plan on Climate Change (NAPCC) guide strategic action.

Recent developments, including the 2023 Forest Conservation Amendment Act and ongoing NGT directives on waste management, highlight the dynamic nature of this field. Remember the 'Three-Pillar Environmental Governance Model' (Legislative, Judicial, Executive) for a holistic understanding.

5-Minute Revision

India's environmental governance framework is a complex interplay of constitutional mandates, statutory laws, policy directives, and judicial pronouncements. The constitutional bedrock includes Article 48A (DPSP) and Article 51A(g) (Fundamental Duty), with the Supreme Court expanding Article 21 (Right to Life) to encompass the 'Right to a Clean Environment.

' The Environment (Protection) Act, 1986 (EPA), serves as the overarching legislation, granting the Central Government extensive powers to regulate environmental quality, emissions, and industrial operations.

This Act is the basis for critical tools like the Environmental Impact Assessment (EIA) Notification, which mandates prior clearance for developmental projects through a multi-stage process involving screening, scoping, public hearing, and appraisal.

Specialized laws address specific environmental concerns: the Water (Prevention and Control of Pollution) Act, 1974, and the Air (Prevention and Control of Pollution) Act, 1981, established the Central Pollution Control Board (CPCB) and State Pollution Control Boards (SPCBs) as key regulatory and enforcement bodies.

The Forest (Conservation) Act, 1980 (FCA), regulates the diversion of forest land for non-forest purposes, while the Wildlife (Protection) Act, 1972 (WPA), protects endangered species and establishes protected areas.

The National Green Tribunal (NGT) Act, 2010, created a specialized tribunal for expeditious environmental justice, applying core principles like 'Polluter Pays,' 'Precautionary Principle,' and 'Sustainable Development.

' Policy frameworks, such as the National Environment Policy, 2006, and the National Action Plan on Climate Change (NAPCC) with its eight missions, provide strategic direction for environmental management and climate action.

Recent developments, like the 2023 Forest Conservation Amendment Act, ongoing NGT directives on waste management, and the Supreme Court's recognition of the 'right against adverse effects of climate change' (2024), underscore the dynamic evolution of this field.

Challenges in implementation include institutional capacity gaps, inter-agency coordination issues, data deficiencies, and enforcement weaknesses. A holistic understanding requires connecting these elements to broader issues like disaster management, urban planning, and economic policy, recognizing the 'Three-Pillar Environmental Governance Model' (Legislative, Judicial, Executive) and the continuous tension between development and conservation.
