India is undergoing a significant influx of urban migration and a reclassification of rural areas, resulting in a rapidly growing urban population projected to reach 612 million by 2030 and 843 million by 2050. Policymakers and industry leaders are working towards achieving a net-zero target by 2070. To further strengthen this ambitious goal, the National Institute of Urban Affairs (NIUA) and Rocky Mountain Institute (RMI) highlighted the urgent need for new housing and infrastructure based on low-carbon strategies across the nation. They launched the “Build Right for the First Time: Scaling Adoption of Net-Zero Carbon Buildings in India” report at the “Heat Resilient and Low Carbon Housing in India” convening in New Delhi. The event witnessed the presence of eminent dignitaries including Dr. Debolina Kundu, Director, National Institute of Urban Affairs (NIUA), Sachin Kumar, Director, Shakti Sustainable Energy Foundation, Satish Chandra Vishnubhatla, Deputy Vice President, Johnson Controls – Hitachi Air Conditioning, Tarun Garg, Principal, RMI India foundation and Dr. S K Chaturvedi, Joint Director, National Council for Cement and Building Materials (NCB).
As India’s urban landscape grows, so does the carbon footprint of its buildings. The report highlights a uniform definition for net-zero carbon structures and outlines five high-impact decarbonization strategies that could collectively reduce up to 8 gigatons (Gt) of emissions by 2050. Notably, these results can be achieved with a modest cost premium of approximately ₹4,566/m² compared to a business-as-usual scenario.
Mr. Satish Chandra Vishnubhatla, Deputy Vice President, Johnson Controls-Hitachi Air Conditioning India Ltd, highlighted the industry-wide challenge of translating policy into actionable solutions. “There is universal agreement on the need to work towards heat-resilient housing and low-carbon housing, yet implementation remains a key challenge at the ground level,” he noted.
Recognizing the critical role of innovation in overcoming barriers to adoption, Mr. Satish emphasized its potential to enable widespread acceptance of sustainable cooling solutions. “Innovation should ease adoption, removing obstacles so that policy can seamlessly transition into action. As a technology leader, Hitachi takes a three-pronged approach to this challenge – firstly, we focus on bringing the most energy-efficient technologies to Indian consumers, thereby reducing the load on the grid. Secondly, Hitachi has developed technologies, such as a self-cleaning function, to ensure the products maintain this efficiency throughout the life of the product. Last but not least, for adoption to happen at the ground level, we communicate the benefits of the technology to the customers in a simple manner without industry jargon,” he added.
In collaboration with RMI, Johnson Controls-Hitachi Air Conditioning is embracing an ambitious challenge—developing air conditioning systems that are 5 times more efficient than conventional systems available in the market, pushing boundaries in energy efficiency. Through groundbreaking innovations, Johnson Controls-Hitachi Air Conditioning is leading the charge toward a carbon-neutral future, setting new benchmarks in sustainable cooling technology.
Ms. Akshima Ghate, Managing Director of RMI India, said, “India stands at a pivotal juncture in its development journey, with rapid urbanization and economic growth set to more than double its building stock by 2050. This moment presents a critical opportunity to align infrastructure expansion with climate goals.”
The report further suggests national and subnational policy interventions to facilitate the implementation of the proposed measures at the sector level. Moreover, it introduces a behaviour change framework to encourage the adoption of net-zero carbon buildings in India, targeting various stakeholders, including policymakers, real estate developers, and industry professionals.
Dr. Debolina Kundu, Director of the National Institute of Urban Affairs (NIUA), requested stakeholders come together to build a coalition for future-ready heat-resilient houses in India and said, “India’s current urban trajectory and economic growth present a once-in-a-generation opportunity to shape a low-carbon and heat-resilient future. We hope this effort empowers stakeholders across the value chain to lead India’s building sector toward a climate-resilient, energy-efficient, and equitable future.”
During the convening, Ms. Mrinalini Shrivastava, IPS, Director, National Disaster Management Authority (NDMA), proposed a platform like an urban heat mitigation lab that would act as a knowledge hub for urban heat mitigation research in India. Dr. Shailesh Agrawal, Executive Director of the Building Material & Technology Promotion Council (BMTPC), also urged innovators to empanel their products as green materials.
This gathering of policymakers, industry leaders, and stakeholders aimed to strengthen India’s housing value chain while addressing the urgent need for decarbonization in the building sector.
