India’s Heatwave Disaster Classification Highlights Global Adaptation Finance Gap Ahead of COP31

India’s official recognition of heatwaves as natural disasters, coming nearly three months ahead of the UN climate change conference (COP31) in Türkiye, has brought a stark reality of the global climate finance system into focus. The move highlights how vulnerable nations are often left to pay for immediate climate survival entirely on their own.

Krishna S Vatsa, National Disaster Management Authority (NDMA) member and Head of the Department, noted that international assistance for heat adaptation measures remains inadequate and unpredictable. According to India's first Adaptation Communication submitted to the UN Climate Change Summit in 2023 (COP28), the country estimated a cumulative expenditure need of ₹56.68 lakh crore for adaptation by 2030.

Data from India's 2025 economic survey indicates that 98 percent of the country's adaptation finance is sourced domestically. The gap between the adaptation funds needed by developing nations and the actual capital reaching them is expected to be a major point of discussion at COP31 in Antalya.

Vatsa emphasized that while India utilizes its own national and state disaster mitigation funds and encourages states to develop heat action plans, international adaptation finance is essential to complement national efforts. He stated that steady, predictable, and consistent access to finance is a prerequisite for long-term adaptation strategies, noting that resources must match the national scale of atmospheric hazards like heatwaves.

Benjamin Hickman, who leads UNEP’s Cool Coalition programme in India, highlighted the institutional capacity and preparation required for climate finance to flow effectively. The UNEP Adaptation Gap report 2025 projects that public capital required for climate survival in developing nations will exceed 310 billion USD annually by 2035, a requirement at least 12 times greater than current international adaptation flows. Hickman noted that pilot testing of finance mechanisms, such as helping people afford efficient air conditioning or protecting homes, is necessary before scaling up through climate finance.

Sanjay Vashist, Director of Climate Action Network South Asia (CANSA), pointed to the UNEP Emissions Gap Report 2026, which indicates that current global policies put the world on a path toward a 2.8 degrees Celsius temperature rise by the end of the century. Vashist stressed that adaptation must be treated as an urgent priority and that developed nations should bear primary responsibility under the Common But Differentiated Responsibilities and Respective Capabilities (CBDR-RC) principle, given their historical and current greenhouse gas emissions.

With adaptation finance for developing countries positioned among the key issues for negotiations, COP31 is scheduled to take place in Antalya, Türkiye, from November 9 to 20.

"The financial strain highlighted by India's domestic funding of 98 percent of its adaptation needs demonstrates a critical infrastructural challenge that extends directly into the business and commercial ecosystem. As climate hazards like heatwaves demand massive capital for cooling technologies, resilient public buildings, and operational adjustments, businesses and enterprises will increasingly need to factor climate adaptation costs into their long-term risk management and strategic planning. Predictable international finance and robust public-private partnerships will be vital to support these transitions sustainably." — Dr. Shishir Gupta, Founder & CEO, StartupLanes
