Strengthening nature governance and alignment with global standards
We are strengthening our nature governance framework by aligning with globally recognised standards and embedding biodiversity considerations into enterprise-wide decision-making. As an official adopter of the Task Force on Nature-related Financial Disclosures (TNFD), we have published our TNFD-aligned disclosure, reinforcing transparency on nature-related dependencies, impacts, risks and opportunities. This marks a significant step in integrating natural capital into our risk management, strategy and long-term value creation.
Tata Power is the first company in India’s Electric Utilities & Power Generators sector to publish a TNFD-aligned disclosure on the TNFD platform and is among the first 11 companies in India to do so.
Additionally, we are advancing our Nature-based Solutions (NbS) approach through deeper alignment with international benchmarks. We conducted a self-assessment using the IUCN Global Standard for NbS for key conservation initiatives, demonstrating strong alignment with global criteria while identifying opportunities for further strengthening.
