In recent months, the German Coast Guard has permitted Russian oil tankers, known as "shadow tankers," to transit through its waters. These vessels, often operating under false flags, are used to circumvent international sanctions imposed on Russia. The decision has sparked debate over Germany's role in enforcing sanctions and the broader implications for European security.
"Shadow tankers" are ships that disguise their origin by registering under different countries' flags, a tactic employed to evade sanctions. A report by the Centre for Research on Energy and Clean Air (CREA) highlighted that over 100 such vessels transported €4.7 billion worth of oil in the first three quarters of 2025. This practice has raised concerns about the effectiveness of sanctions and the potential environmental risks posed by these aging ships.
The German Coast Guard's decision to allow these vessels to pass has been met with criticism. Critics argue that it undermines the sanctions regime and could lead to environmental hazards, as many of these ships are poorly maintained. However, supporters contend that Germany is adhering to international maritime laws, which grant vessels the right of innocent passage through territorial waters, provided they do not pose a threat to the environment or violate other regulations.
The situation underscores the challenges faced by European nations in balancing the enforcement of sanctions with international maritime obligations. As the use of shadow tankers continues to rise, it remains to be seen how Germany and other European countries will navigate this complex issue.
