Preserving Himalayan Glaciers
The Problem
The Himalayan glaciers—often referred to as the “Third Pole”—are melting at an accelerating rate due to global warming, posing a critical threat to water security, agriculture, and economic stability across Asia. These glaciers feed major river systems that sustain nearly 2 billion people. Scientific projections indicate that over 50% of Himalayan glacier volume could be lost by 2050, triggering severe water shortages, floods, and large-scale displacement . This crisis represents not only an environmental emergency but a systemic risk to regional stability, food security, and long-term economic resilience.
Our Solution
The Healthy Climate Initiative (HCI), in collaboration with IIT Indore and the Bright Ice Initiative (USA), is developing a scalable, nature-safe solution to slow glacier melt. The approach uses White Glacier Granules (WGG)—an eco-friendly reflective material made from natural clay—to increase surface reflectivity (albedo), reducing solar heat absorption and slowing ice loss.
Designed as a low-cost, deployable, and scientifically validated intervention, this solution offers a practical and high-impact climate adaptation pathway. It builds on over a decade of prior research in the Arctic, where reflective materials such as hollow glass microspheres demonstrated the potential to significantly reduce ice melt—even when applied to a small surface area.
Three-Phase Program (2024 – 2027)
Phase I – Proof of Concept (2024):
Conducted at the Chhota Shigri Glacier, this phase validated the effectiveness of WGG using controlled test and control plots, supported by real-time monitoring through weather stations and ablation sensors. An Environmental Impact Assessment (EIA) confirmed the ecological safety of the materials and methods.
Phase II – Performance Evaluation (2026):
This phase expands testing across diverse glacier conditions—including varying elevations, slopes, and surface types—to assess durability, consistency, and long-term performance. Additional monitoring and a follow-up EIA will ensure continued environmental safety and robustness.
Phase III – Scaling & Validation (2027):
The final phase will demonstrate large-scale deployment, integrating satellite-based monitoring with field data to validate regional impact and scalability. A comprehensive EIA will support safe and sustainable implementation at scale.

Phase I Field Trials (October 2024) | Strong, measurable outcomes:
- 58% reduction in glacial melt compared to untreated areas
- 134% increase in surface reflectivity (albedo)
- Successful validation of environmental safety through Environmental Impact Assessment (EIA)
Expected Outcomes
Project Objectives
Deliver a validated, environmentally safe, and scalable solution to significantly slow glacier melt by 2027, providing a critical climate adaptation tool for vulnerable regions.
Generate and disseminate high-quality scientific evidence, including peer-reviewed publications and presentations at leading global climate forums, to establish global credibility and accelerate adoption.
Enable large-scale adoption and policy integration by equipping UN agencies and Himalayan nations with proven frameworks, field data, and implementation models to replicate and scale the solution.
Sustainability & Replication Plan
The outcomes of this initiative are designed to establish a scalable and replicable framework for glacier preservation across the Himalayas. By 2028, the program will integrate advanced climate modeling simulations to identify optimal locations and timing for deploying reflective materials, maximizing impact and cost-effectiveness.
Building on prior Arctic modeling—where reflective materials demonstrated the ability to significantly reduce ice melt and even promote regrowth—we hypothesize that WGG can deliver similar outcomes in the Himalayan context by reflecting solar radiation and slowing melt rates.
Successful validation will form the basis for a national pilot program, developed in partnership with leading Indian research institutions and policymakers. This will ensure the methodology’s scientific rigor, environmental sustainability, affordability, and scalability. Beyond India, the initiative is expected to catalyze international collaboration in cryosphere preservation and water security, creating a globally relevant model for protecting vulnerable ice systems.
