The Conference was formally inaugurated by Justice M.M. Sundresh, Judge, Supreme Court of India. The inaugural session commenced with Justice Pushpa Sathyanarayana extending a warm welcome to the dignitaries and participants. In his address, Justice Prakash Shrivastava emphasized that environmental protection is not merely a constitutional mandate under Articles 21, 48(A), and 51(A)(g), but also a shared moral responsibility. He highlighted that the NGT's initiatives extend beyond adjudication to creating awareness and guiding institutions toward sustainable environmental practices. Guest of Honour Mr. P. S. Raman, Advocate General of Tamil Nadu, stressed the need for strengthening environmental governance, quoting Hubert Reeves on human insanity and underscoring sustainable development. Thangam Thennarasu, Minister, Government of Tamil Nadu, spoke about the State's evidence-based environmental journey, noting Tamil Nadu's unique geographical identity and cultural ethos, and reaffirmed that environmental protection is deeply rooted in its tradition, ecological wisdom, and developmental priorities.
Justice Manindra Mohan Shrivastava, Chief Justice of the High Court of Madras and Guest of Honour, expressed concern over the alarming global decline in wildlife populations, referencing a WWF report indicating an almost 69% decrease in populations of mammals, birds, fish, reptiles, and amphibians. He emphasized the need for preventive measures to safeguard humanity itself from becoming endangered. Special Guest Justice Aravind Kumar, Judge, Supreme Court of India, highlighted the gap between “law on paper and life on the ground” and proposed the idea of “cooperative ecological federalism” among the southern states, suggesting that the conference could mark the beginning of a “Southern Environmental Compact.” Justice M.M. Sundresh, in his address, stressed the significance of traditional wisdom and shared personal experiences concerning communities affected by dyeing industry pollution, stating that “when the environment is impacted, the world gets affected.” He also emphasized the urgent need to protect coastal zones.
The Technical Sessions addressed critical environmental challenges. The first session, chaired by Justice A. Muhamed Mustaque, Judge, High Court of Kerala, focused on Environmental Law Enforcement and Biodiversity Conservation. Justice Mustaque questioned whether existing laws adequately address issues such as E-waste pollution, adding that “something lawful cannot be harmless,” highlighting that legal activities may still cause environmental harm. He pointed out regulatory and town-planning deficiencies that overlook long-term environmental consequences. Dr. R. Nagendran, Former Expert Member, NGT, Southern Zone Bench, stressed the need for biodiversity-specific Environmental Impact Assessments and stronger coordination among regulatory agencies. Mr. Raghuram highlighted the implementation of the Biological Diversity Act, 2002, and the NBA's initiatives to enhance benefit-sharing for native communities. Dr. Indumathi M. Nambi, Professor at IIT Madras, shared her experience on suo motu environmental cases, including the Ennore and Kanchipuram oil spills, pointing out challenges arising when expert committee reports are repeatedly returned for reconsideration.
The second session, chaired by Justice D. Bharatha Chakravarthy, Judge, High Court of Madras, focused on Solid Waste and Biomedical Waste Management. Justice Chakravarthy cited the judgment delivered by Justice Suraj Govindaraj in WP 27475 of 2025, which encouraged the integration of technologies such as surveillance systems, performance scorecards, GIS-based route mapping, and robotic segregation of biomedical waste. He emphasized that cities must evolve into “Recycle and Recompose” ecosystems and referenced a study from Coimbatore that detected microplastics in human placenta, underscoring the urgency for systemic change. Dr. Justice P. Jyothimani, Former Judicial Member, NGT, and Former Judge of the High Court of Madras, questioned whether statutory waste-management targets have been achieved in India and remarked that non-compliance persists due to a lack of public intention. He stressed that unless rules are enforced strictly, progress will remain slow, emphasizing the importance of citizen awareness, responsibility, and education in waste management. He reiterated that real solutions must come from citizens as much as from legal provisions.
Dr. D. Karthikeyan, IAS, Principal Secretary, Municipal Administration & Water Supply Department, Government of Tamil Nadu, discussed the complexities of solid and biomedical waste management in the State. He highlighted insights from a comprehensive study on Tamil Nadu's waste management framework and noted advancements anticipated under the Draft Solid Waste Management Rules, 2024, particularly in technological interventions. Mr. Arun Krishnamurthy, Founder of the Environmentalist Foundation of India (E.F.I.), pointed out the disparity between urban waste management and the neglect of municipal and panchayat-level regions. He noted that despite periodic clean-up efforts, water bodies such as Sitalapakkam Lake quickly return to polluted conditions due to unchecked waste dumping. He stressed the need for accountability and citizen participation, citing the situation at Arasankadali Lake, where damaged fencing and nearby hillocks have become dumping sites.
The first day of the Conference concluded with all stakeholders reaffirming their commitment to strengthening environmental governance, enhancing regulatory coordination, and promoting sustainable development practices. The deliberations collectively reinforced the shared responsibility to safeguard the environment for future generations.
