$12 Trillion Needed for Climate Mitigation Needs in Hindu Kush Himalayas: Report
📅 January 6, 2026
✍️ Editor: Sudhir Choudhary, The Vagabond News
An estimated $12 trillion will be required by the end of the century to meet climate mitigation and adaptation needs in the Hindu Kush Himalayas, according to a new scientific assessment that warns of escalating environmental, economic, and humanitarian risks across one of the world’s most climate-vulnerable regions.
The report, released by the International Centre for Integrated Mountain Development (ICIMOD), highlights the immense financial challenge facing countries dependent on the Hindu Kush Himalayan (HKH) region, which spans eight nations including India, Nepal, Bhutan, Pakistan, China, Afghanistan, Bangladesh, and Myanmar.
A Region at the Climate Frontline
Often referred to as the “Third Pole” because it holds the largest concentration of ice and snow outside the Arctic and Antarctic, the Hindu Kush Himalayas are warming faster than the global average. Scientists warn that even if global warming is limited to 1.5°C, the region could still lose up to one-third of its glaciers by 2100.
The report estimates that trillions of dollars will be needed to fund measures such as glacier monitoring, disaster-risk reduction, climate-resilient infrastructure, sustainable agriculture, water management systems, and renewable energy transitions in fragile mountain ecosystems.
“The cost of inaction will be far higher than the cost of action,” the report said, warning that climate impacts in the HKH region could destabilise food systems, water security, and livelihoods for nearly two billion people downstream.
Why the Costs Are So High
The HKH region feeds 10 major river systems, including the Ganga, Indus, Brahmaputra, and Mekong. Accelerated glacier melt, erratic rainfall, and rising temperatures are already increasing the frequency of floods, landslides, glacial lake outburst floods (GLOFs), and prolonged droughts.
According to the report, the projected $12 trillion requirement includes:
-
Investments in climate-resilient infrastructure and disaster preparedness
-
Protection of mountain biodiversity and forest ecosystems
-
Transition to clean energy in remote and high-altitude regions
-
Adaptation support for indigenous and mountain communities
-
Regional cooperation mechanisms for shared river basins
Researchers stressed that mountainous regions face higher per-capita adaptation costs due to difficult terrain, limited connectivity, and fragile ecosystems.
A Call for Global Climate Finance
ICIMOD has called for scaled-up international climate finance, arguing that countries in the HKH region contribute relatively little to global greenhouse gas emissions but bear a disproportionate share of climate impacts.
The report urges developed nations and multilateral institutions to increase grants and concessional finance, rather than loans, to help mountain countries adapt without falling into debt traps.
“Mountain regions are global public goods,” the report said. “Their glaciers regulate water flows far beyond national borders, and their collapse would have cascading global consequences.”
India and Regional Implications
For India, which shares a significant stretch of the Hindu Kush Himalayan range, the findings underline the urgency of investing in climate adaptation in Himalayan states. Experts say the report should inform national planning on water security, hydropower development, and disaster management.
Environmental analysts also emphasised the need for cross-border cooperation, noting that climate risks in the Himalayas do not respect political boundaries.
What Lies Ahead
The report concludes that while the $12 trillion figure is daunting, delayed action would multiply costs through disaster losses, displacement, and ecosystem collapse. It calls for urgent integration of mountain-specific climate strategies into national and global climate agendas.
As climate negotiations increasingly focus on finance and adaptation, the Hindu Kush Himalayas are emerging as a stark reminder that some of the world’s most critical regions are also among the least protected.
