The Medog site sits in a region defined by volatile tectonics, rapid climate warming, glacial retreat, and fragile sediment structures. Recall the January 2025 earthquake on the Tibetan Plateau that caused massive damage to human life, ecology, and security. Combined with the political sensitivities surrounding Tibet and China’s upper-riparian status, the project raises a series of questions that cannot remain outside the purview of global climate governance, especially the United Nations Framework Convention on Climate Change (UNFCCC).
Two critical questions become unavoidable: can the UNFCCC maintain credibility if it overlooks the destabilizing ecological impacts unfolding on the Tibetan Plateau? And what happens when one country’s ‘green’ initiative directly compromises the climate resilience and water security of an entire region?

Interpreting China’s Internal Narrative
[Chinese] state agencies, the National Development and Reform Commission (国家发展和改革委员会), the Ministry of Water Resources (水利部), and powerful state-owned energy corporations, present the dam as a logical extension of China’s historical expertise in water engineering. State media narratives emphasize national rejuvenation, infrastructural leadership, and the moral legitimacy of transitioning to renewable energy. Medog has been lauded as a key project, one that supports China’s ambitions for net-zero emissions and clean energy development.
However, beneath this confident exterior lie quieter debates within China’s scientific community. Hydrologists, environmental researchers, and geologists have expressed unease regarding the project’s feasibility and safety. Some studies published in domestic academic journals, though often constrained by political sensitivities, highlight the extreme seismic volatility of the Indo-Tsangpo Suture Zone (印‑藏缝合带). This region sits along the collision boundary of the Indian and Eurasian tectonic plates. Drilling vast tunnels through this terrain may disturb permafrost layers, trigger mass wasting events, or alter the course of subterranean water flows.

The principle of climate justice must extend to Himalayan and South Asian communities that bear the consequences of decisions made far upstream. Adaptation and loss-and-damage frameworks cannot ignore water-related vulnerabilities in the Brahmaputra basin. Indeed, the Medog project strengthens the argument for the UNFCCC to formally recognize Tibet as a critical climate zone whose stability is essential to continental resilience.
The UNFCCC must insist that China conduct transparent, independent environmental impact assessments; share real-time hydrological data; and participate in regional water-governance frameworks that include India and Bangladesh.
In the end, the Medog dam is not merely a Chinese domestic project but a bellwether for the integrity of the global climate system. If Tibet continues to be treated as an internal developmental frontier rather than a global ecological asset, the world risks overlooking one of the most important climate flashpoints of the 21st century.
