War Emissions, Russia’s Invasion of Ukraine, and Just War Theory

The Russian invasion of Ukraine on February 24, 2022, has already caused large amounts of greenhouse gas (GHG) emissions and will continue to do so for many years after hostilities have ceased mainly because of the emissions linked to the rebuilding of destroyed or damaged housing, public buildings, infrastructure, factories, and the like. My aim in this paper is to discuss how in a time of climate emergency such emissions of war should impact the political morality of states initiating, continuing, and ending war (through a just and enduring peace) as understood by just war theory (JWT). My point of departure is a study by Lennard de Klerk and six co-authors detailing the emissions of the first year of the Russo-Ukrainian war.
