The Russia-Ukraine crisis has not only dramatically changed the EU’s security situation but also poses challenges well beyond the security arena. The conflict between Europe’s main energy supplier and its most important gas transit country has already had an impact on regional energy cooperation. The gas-price dispute between Russia’s Gazprom and Ukraine’s Naftohaz has halted gas deliveries to Ukraine. This in turn has raised fears of potential disruptions of gas supplies to the rest of Europe, putting energy security and solidarity mechanisms in the spotlight. The conflict also has had an obvious humanitarian dimension with the wide displacement of people from areas with fighting. Estimates of these people show many Ukrainians are seeking shelter in the EU. With the beginning of the new legislative cycle, the EU has the chance to respond to these outside events through its own internal logic of action. But have the lessons been fully understood? Is Europe lacking some instruments specific to the current crisis or are the deficiencies more structural? Find out in the new publication by the GoodGov project in which its authors analyse the impact of the Russia-Ukraine crisis on EU security, energy and migration and take a closer look at Poland and Norway, two medium-size countries with different relations with the EU.
