Nord Stream 2 would double the amount of gas Russia can pump directly to Germany, its biggest customer for gas, make Germany and Europe less vulnerable to supply interruptions caused by disputes between Russia and Ukraine, and bring economic benefits to Mecklenburg-Vorpommern, a relatively deprived region that used to be in the German Democratic Republic.

But this year as Russia stepped up pressure on Ukraine, questions mounted around the Foundation, called Klima-und Umweltschutz MV (Climate and Environment Protection Foundation). It would not reveal who was running its sanctions-busting operation beyond saying that the person was appointed by Nord Stream 2 AG, a company owned by Gazprom PAO, which is fully controlled by the Russian state.

Asked who that was, Swiss-based Nord Stream 2 did not respond. Gazprom did not respond to a request for comment.

The state auditor, the Court of Auditors, told Reuters on Feb. 9 it was concerned that Mecklenburg-Vorpommern had largely given up control over the Foundation’s assets. This meant there was no guarantee that the Foundation would always work in the public interest, said Sebastian Jahn, the court’s spokesman, in a telephone interview.
