While the law of the sea is rightly viewed as the most suitable
international legal regime for the settlement of disputes in the Arctic, the
militarization of this region in an era of climate change is also
observable. Yet curiously, scant attention has been paid to the constraints
the international humanitarian law (IHL) would impose on armed conflict in
the Arctic, as unlikely as such conflict may be. These constraints include
the specific prohibition on causing widespread, long-term, and severe
environmental damage under Additional Protocol I to the Geneva Conventions
as well as the related obligation to have “due regard” for the natural
environment, as referred to in, for example, the San Remo Manual on
International Law Applicable to Armed Conflict at Sea.
Similarly, environmental factors must play into military assessments of
targets based on the general principles of IHL related to targeting. The
authors explore how these various legal obligations could be applied in the
Arctic context. Referring to the scientific literature, they suggest that,
due to the particularly vulnerable nature of this regional environment, many
traditional war-fighting techniques would lead to damage that is not legally
permissible. This conclusion should provide an additional incentive to
policy makers to demilitarize the Arctic and to solve peacefully any
disputes that may arise over sovereignty, navigation, or resources.
