As part of the inaugural event, Bharatiya Vidya Bhavans Atmakuri Ramarao School, (Benefits to Environment), Kendriya Vidyalaya BSF Camp Chhawla, Delhi (Education & Awareness) and Navy Children School, Karwar, Karnataka (Innovation Category) were recognized and awarded as winners for the Green Your School Programme.

Founded with a singular motto of instilling a sense of Green amongst young minds, IGBC also initiated a Green Your School Programme for classes starting from 8th to 10th and has been successfully recognizing innovative ideas and initiatives from school children to become a greener nation for the past 17 years. Along with the launch of the new Net Zero Carbon Ration System, IGBC also released updated versions of its existing rating systems for existing buildings, green campuses, and green factories.

Sharing his view on the newly launched Net Zero Rating System, Mr. Gurmit Singh Arora, Chairman – of IGBC and chairman – of Green Building Congress 2023 said “The Government of India over the last two decades has initiated several new missions and policies which support the path towards net zero carbon buildings, cities, and nation. The building sector of our country has an excellent opportunity to take the leadership role for accelerating the uptake of Net Zero. The Green Building Movement in India has been spearheaded by CII’s IGBC since 2001, by creating awareness amongst the stakeholders.

Thus far, the Council has been instrumental in enabling 10.42 billion sq.ft. of green building footprint in the country. The Council’s activities have enabled a market transformation, particularly in green building materials and technologies. IGBC continuously works to provide tools that facilitate the adoption of green building practices in India. The newly launched Net Zero Rating System is an initiative aimed at facilitating the adoption of Net Zero concepts to support market transformation towards total building sector decarbonization and to accelerate the adoption of Net Zero concepts in the country.”

Mr. Gurmit Singh Arora further added “The benefits of this rating system are multifaceted. Beyond supporting India’s climate goals through carbon reduction, it encourages resource efficiency, adoption of energy-efficient systems, integration of renewable energy sources, responsible water use, waste minimization, and climate-resilient building designs. The rating system presents an excellent opportunity for the building sector to lead the adoption of Net Zero practices and facilitate India’s transformation into one of the foremost countries achieving Net Zero by 2050.”

Adding to this, Mr. Ajit Chordia, Chairman, IGBC Chennai Chapter said “We are pleased to host our annual flagship event – Green Building Congress 2023 in Chennai. We are sure this event will significantly contribute to reinforcing India’s position as a leader on the global green buildings map. We appreciate the Tamil Nadu government for its efforts towards achieving sustainable goals in the pursuit of moving towards Net Zero waste, water, energy, and carbon. Tamil Nadu’s commitment towards the green building movement can be witnessed through many landmark projects such as the IGBC-certified buildings – Anna Centenary Library, Chennai Metro Rail Limited, Smart Governance Centre, and many more. This three-day conference is set to unearth many innovative models of achieving Net Zero Carbon future and we are confident that there will be significant takeaways for everyone.”

The launch of the IGBC Net Zero Carbon rating system is in alignment with ‘IGBC’s Mission on Net Zero’ launched on Earth Day in 2021 and India’s commitment at COP 26 i.e., achieving the long-term goal of reaching Net Zero carbon in emissions by 2070. The rating system operates on a voluntary and consensus-based approach, promoting the use of low-embodied carbon materials and technologies, on-site or off-site renewable energy sources, and adherence to a Whole Building Life Cycle Analysis as per ISO Standard 14040. The rating system addresses projects in both the ‘Design & Construction’ and ‘Operations’ phases. This approach allows tailored strategies for minimizing or eliminating carbon emissions at different project stages.

I am sure that the deliberations in the next three days will help the stakeholders to understand the strategies to be taken to achieve the common goal for Net Zero.”

Concluding the session, Mr. B Thiagarajan, National Vice Chairman of, the Indian Green Building Council said “While going green is imperative in the built environment industry, there is also a greater emphasis that needs to be placed on the availability of technology and products that support in facilitating the transformation. For this, we have curated a large-scale exhibition space for various stakeholders in the value chain to showcase their innovative products.
