1. Understanding Environmental Impact Assessment Laws in India

Environmental Impact Assessment (EIA) is a systematic process to evaluate the environmental, social, and economic impacts of a proposed project before it is approved, ensuring that development aligns with sustainability goals.

• Definition: EIA is a decision-making tool that predicts the environmental effects of a project, proposes mitigation measures, and offers alternatives to decision-makers, aiming to reduce adverse impacts while promoting sustainable development.
• Objective: The primary goal of EIA laws in India is to ensure optimal use of natural resources, minimize environmental degradation, and promote community participation in decision-making, as emphasized by the United Nations Environment Programme (UNEP).
• Scope: In India, EIA is mandatory for 40 categories of developmental activities, including mining, oil and gas exploration, nuclear power, and township development, provided the investment exceeds INR 500 million, as per the EIA Notification, 2006.
• Process: The EIA process involves four stages: screening (identifying projects requiring assessment), scoping (determining the extent of the study), public consultation (involving stakeholders), and appraisal (evaluating the EIA report for clearance).

The Environmental Impact Assessment Laws in India: Challenges Ahead underscore the need to strengthen this framework to address emerging environmental threats effectively.

2. Historical Evolution of EIA Laws in India

The journey of EIA laws in India reflects the country’s growing recognition of environmental concerns amidst rapid industrialization.

• Early Beginnings (1970s): The Indian experience with EIA began in 1976-77 when the Planning Commission tasked the Department of Science and Technology with examining river-valley projects from an environmental perspective. This was later extended to projects requiring Public Investment Board approval.
• Formalization (1994): Until 1994, environmental clearances were administrative decisions without legislative backing. On January 27, 1994, the Ministry of Environment and Forests (MoEF) issued the EIA Notification under the Environment Protection Act, 1986, making environmental clearance mandatory for specified projects, marking a significant step toward formalizing EIA laws.
• Amendments and Evolution: The EIA Notification of 1994 has seen 12 amendments, with the 2006 Notification being a key overhaul that streamlined the process and introduced public consultation as a mandatory step. However, the 2020 draft EIA Notification sparked controversy, as it proposed measures like ex post facto clearances, which were deemed illegal by the Supreme Court in cases like Alembic Pharmaceuticals Ltd v. Rohit Prajapati (2020).
• Judicial Oversight: The judiciary has played a pivotal role in shaping EIA laws, with cases like M.C. Mehta v. Union of India (1986) advocating for specialized environmental courts, leading to the establishment of the National Green Tribunal (NGT) in 2010.

This historical context sets the stage for understanding the Environmental Impact Assessment Laws in India: Challenges Ahead, as past reforms reveal persistent gaps in implementation and enforcement.

3. Legal Framework Governing EIA Laws in India

The Environmental Impact Assessment Laws in India: Challenges Ahead are rooted in a legal framework designed to balance development with environmental protection, but its effectiveness is often questioned.

• Environment Protection Act, 1986: The EPA provides the statutory backing for EIA in India, empowering the central government to regulate activities that impact the environment. Section 3 of the EPA authorizes the issuance of notifications like the EIA Notification.
• EIA Notification, 2006: This notification, amended multiple times, mandates EIA for specified projects, outlining the process of screening, scoping, public consultation, and appraisal. It requires environmental clearance for 40 categories of projects, such as mining and thermal power plants, with investments above INR 500 million.
• Role of Regulatory Bodies: The Central Pollution Control Board (CPCB) and State Pollution Control Boards (SPCBs) oversee enforcement, conducting inspections, ensuring compliance through periodic reporting, and imposing penalties for violations. The State Environment Impact Assessment Authority (SEIAA) appraises projects at the state level.
• Judicial Oversight: The Supreme Court, High Courts, and NGT play a significant role in enforcing EIA laws. The NGT, established in 2010, has taken suo motu cognizance of environmental violations, while the Supreme Court has simplified locus standi for environmental public interest litigation (PIL), enabling broader access to justice.
• International Influence: The Rio Declaration (1992) emphasized EIA as a national instrument for projects with adverse environmental impacts, influencing India’s adoption of international standards like public participation and sustainable development.

This legal framework, while robust on paper, faces significant challenges, as explored in the Environmental Impact Assessment Laws in India: Challenges Ahead.

4. Key Impacts of EIA Laws in India

EIA laws in India have had a transformative impact on environmental governance, but their implementation reveals both strengths and weaknesses.
