Environmental clearance and compliance have become critical business imperatives with over 45,000 projects requiring environmental clearances annually and penalties reaching ₹1 lakh per day for violations under India's strengthened environmental protection framework. The Environmental Impact Assessment (EIA) Notification 2006 mandates clearances for projects in mining, infrastructure, chemicals, and manufacturing above specified thresholds, while State Pollution Control Boards regulate day-to-day operations through Consent to Establish (CTE) and Consent to Operate (CTO) approvals. With increasing environmental scrutiny, digital monitoring systems, and climate change commitments, understanding clearance procedures, compliance obligations, and sustainable business practices is essential to avoid project delays, operational shutdowns, and multi-crore penalty exposures while contributing to India's net-zero goals.
Sustainability Focus: India's commitment to net-zero by 2070 requires businesses to adopt green practices, obtain environmental clearances, and implement sustainable operations for long-term viability.
Environmental Compliance Overview
India's Environmental Regulatory Framework
India's environmental compliance regime is built on a comprehensive legal framework comprising the Environment Protection Act 1986, Water (Prevention and Control of Pollution) Act 1974, Air (Prevention and Control of Pollution) Act 1981, and various rules and notifications. The system operates through a multi-tiered structure with central clearances for large projects and state-level approvals for smaller projects, ensuring environmental protection while facilitating sustainable economic development. The regulatory framework emphasizes preventive measures through Environmental Impact Assessment, pollution control through technology standards, and corrective action through monitoring and penalties.
