Greenland is emerging as one of the most resource-rich regions on Earth, combining vast geological wealth with growing geopolitical and environmental significance. Greenland natural resources include critical raw materials such as lithium and rare earth elements (REEs), alongside precious metals, industrial minerals, and enormous hydrocarbon reserves of oil and gas. These materials are essential for green technologies, batteries, wind turbines, electric vehicles, and advanced electronics, placing Greenland at the centre of the global energy transition.
A defining feature of Greenland natural resources is that much of this wealth lies hidden beneath ice. Although Greenland’s ice-free land area is nearly twice the size of the UK, it represents less than 20 percent of the island’s surface. This raises the likelihood that substantial, largely unexplored reserves remain locked beneath kilometres of ice. Studies suggest that three sub-ice REE-bearing deposits may rank among the world’s largest by volume, potentially supplying materials vital for batteries and electrical components on a global scale.
The exceptional concentration of resources in Greenland is rooted in a geological history spanning four billion years. Some of Earth’s oldest rocks are found here, alongside unusual features such as large masses of native iron and diamond-bearing kimberlite pipes. What makes Greenland particularly remarkable is that it has experienced all three major geological processes responsible for forming natural resources: mountain building, rifting, and volcanic activity. This rare combination has generated oil and gas, REEs, metals, and gemstones within a single region.
Mountain-building episodes fractured the crust, allowing gold, rubies, and graphite to form in faults and fractures. Graphite, a key component of lithium-ion batteries, remains relatively underexplored despite its strategic importance. However, the largest share of Greenland natural resources originates from periods of rifting, most notably during the opening of the Atlantic Ocean around 200 million years ago. These events created sedimentary basins such as the Jameson Land Basin, which are geologically comparable to Norway’s hydrocarbon-rich continental shelf.
Hydrocarbon potential has drawn strong international attention. The US Geological Survey estimates that onshore northeast Greenland could contain around 31 billion barrels of oil-equivalent hydrocarbons, comparable to the total proven crude oil reserves of the United States. Offshore, emerging research points to petroleum systems that may encircle much of the island, although high costs and harsh conditions have limited exploration.
Volcanic processes have also played a critical role, especially in forming REEs such as niobium, tantalum, ytterbium, neodymium, and dysprosium. Unlike nearby Iceland, Greenland is not located directly on a mantle plume, yet hydrothermal activity linked to ancient volcanism concentrated these scarce elements. Sub-ice reserves of neodymium and dysprosium alone could meet more than a quarter of projected future global demand, potentially reshaping global supply chains.
Climate change now presents a profound dilemma. Melting ice is making Greenland natural resources increasingly accessible, aided by technologies such as ground-penetrating radar that can map bedrock beneath up to two kilometres of ice. Yet extracting these resources risks accelerating environmental damage, contributing to sea-level rise and threatening Greenland’s fragile landscapes and coastal communities. While strict regulations have governed mining since the 1970s, mounting geopolitical interest and climate-driven accessibility mean difficult choices about Greenland’s future are approaching fast.
