Greenland has been studying Alaska's mineral industry up close, with an eye on how to develop its own resources. A field trip examined the environmental regulatory requirements Alaska's mining companies face and how the industry's footprint on society is assessed. The visit was framed as serious preparation for what may come next in the territory. Greenland is expected to need heavy investment from outside if mining there is to move forward on a large scale. US Senator Lisa Murkowski was among those commenting, pointing to the major investor interest the Arctic attracts. Deposits of minerals that global manufacturers want sit under Greenland's ice and rock, which is exactly why questions about responsible development have grown louder. Seeing an established mining jurisdiction at work gives Greenlandic policymakers concrete reference points on permitting and oversight.
