Over the past decades, Russia has sought to expand natural gas exports, necessitating construction of pipelines to Europe and China. In addition to profits for the Russian state, fossil fuel exports are a valuable tool for Moscow’s geopolitical ambitions. Since the start of the war in Ukraine in 2014 and the full-scale invasion in 2022, the economic and political stakes have skyrocketed. Russia”s green movements had previously been able to mobilize effective campaigns, winning concessions on pipeline routes through natural areas. Since 2014, however, they have come under increasingly harsh scrutiny from the Russian government, with organizations branded “undesirable” or declared “foreign agents.” Control of pipelines routes through Ukraine itself are also a goad of the Russian war effort. Eugene Simonov and Jennifer Castner of the Ukraine War Environmental Consequences Work Group demonstrate how war fever and militarization threaten resources and ecology across the Russian Federation as well as in Ukraine.
