Mountainous landscapes store far more carbon than previously thought, new research shows
Hilly and mountainous landscapes have a much greater ability to store carbon in the soil than previously thought, according to a new study co-led by scientists at the University of Oregon.

The revelation that mountainous regions sequester far more carbon than previously estimated could fundamentally reshape climate mitigation strategies. If these ecosystems are as critical as the research suggests, they may represent a previously underutilized lever in global efforts to curb atmospheric carbon dioxide—one that could complement reforestation and wetland restoration while offering a more durable carbon sink.
Background Context
Historically, soil carbon storage research has focused on flat, lowland ecosystems like grasslands and peatlands, where organic carbon accumulation is more visually apparent. Mountainous terrain was often overlooked due to logistical challenges in sampling steep, remote areas and the assumption that erosion and runoff would limit long-term sequestration. Yet these landscapes cover nearly a quarter of Earth’s land surface, making their overlooked potential particularly consequential.
What Happens Next
The study’s findings will likely prompt a surge in funding for alpine soil research, with scientists racing to quantify carbon stocks in specific mountain ranges before climate change accelerates permafrost thaw and glacial retreat. Policymakers may soon face pressure to integrate mountainous regions into national carbon accounting frameworks, potentially creating new incentives for conservation or even geoengineering projects in fragile high-altitude ecosystems.
Bigger Picture
This discovery aligns with a growing body of evidence challenging the notion that carbon storage is confined to "traditional" sinks like forests and oceans. As climate science grapples with the limits of current mitigation approaches, the emphasis on unconventional reservoirs—from deep ocean trenches to urban green spaces—reflects a broader shift toward redefining where and how carbon can be safely sequestered in a warming world.
