As we advance toward a net-zero future, IGBC remains fully committed to working with government, industry, and communities to accelerate green adoption, drive innovation, and build a climate-resilient, people-centric tomorrow.”

Day 1 of the Green Building Congress was marked by several major launches that highlighted IGBC’s role in pioneering sustainable transformation across India’s building sector. One of the key highlights was the launch of the Green Hotels Rating System – Pilot Version, a milestone initiative designed to support India’s rapidly expanding hospitality sector as it moves toward carbon-neutral and resource-efficient operations. With the hotel industry projected to reach $45.39 billion by 2030, the new rating system provides a comprehensive framework that addresses both environmental performance and enhanced guest wellbeing. It covers sustainable site planning, water and energy efficiency, responsible material use, improved indoor environmental quality, and green operations and housekeeping. By embedding sustainability across the entire hotel lifecycle, the rating system aims to enable hotels in metro, Tier II, and Tier III cities to upgrade their infrastructure, reduce their environmental footprint, and deliver healthier and more comfortable experiences for guests.

The day also witnessed the launch of the IGBC Green New Buildings Rating System – Version 4, an advanced and future-ready framework chaired by Ramesh Nair, CEO, Mindspace Business Parks REIT. The updated rating introduces cutting-edge focus areas such as embodied carbon accounting, zero water discharge strategies, enhanced material resource circularity, demand-control ventilation, decarbonization pathways with GHG incentives, and strengthened ESG integration. These enhancements reflect the rapid evolution of building technologies and the need for India’s construction industry to adopt robust climate-responsive practices. Version 4 is expected to guide thousands of upcoming projects in meeting national and global sustainability benchmarks.

Reinforcing its commitment to technology-driven governance, IGBC launched the Automation Tool for IGBC Green Homes and Green Interiors. This digital platform simplifies the submission, review, and certification process through intuitive dashboards, automated validation checks, and standardized formats. The tool is part of IGBC’s broader endeavour to fully automate rating system workflows from project registration to certification issuance. Features such as AI-enabled preliminary assessments, planned for phased rollout, will help accelerate review cycles and improve accuracy. The introduction of this platform marks a significant step toward increasing transparency and streamlining the certification ecosystem for developers, consultants, and project teams nationwide.

Another major highlight was the release of India’s first comprehensive embodied carbon baseline report titled “Embodied Carbon Emissions Baseline Estimation for Buildings in India,” developed with support from the SED Fund. This landmark study uses Life Cycle Assessment methodologies and data from 20 case-study partners to establish upfront embodied carbon intensities across five key building typologies, along with variations across climatic and seismic zones. As India progresses rapidly in addressing operational carbon in buildings, the report emphasizes the urgent need to integrate embodied carbon considerations into design and procurement decisions. The insights are expected to shape future policies, drive innovation in low-carbon materials, and support developers and architects in making informed choices that reduce total life cycle emissions.

Alongside these launches, Day 1 featured the International Conference on Green Buildings & Built Environment, which brought global and national experts together to discuss climate-resilient urban planning, net-zero strategies, green finance, and the future of sustainable construction. The conference placed particular emphasis on Mumbai’s evolving infrastructure landscape and the need for resilient, efficient, and equitable building solutions. Complementing the conference, the Expo on Green Building Products, Materials & Technologies showcased advanced solutions ranging from low-carbon materials and high-performance HVAC systems to renewable energy technologies, water-saving innovations, and circular construction tools. Exhibitors and attendees engaged in meaningful exchanges to drive the adoption of cutting-edge innovations across India’s built environment sector.

The opening day of IGBC Green Building Congress 2025 set a powerful tone for the three-day event, combining visionary leadership, pioneering tools and ratings, and data-driven insights that reinforce India’s commitment to building a greener future. The Green Building Congress will continue over the next two days with sectoral conferences on green finance, net-zero homes, reimagined workspaces, green energy in buildings, green factories, and logistics parks, along with leadership sessions and B2B engagements that will further advance the green building movement.
