In December, Vienna threatened to torpedo Brussels' 12th sanctions package after Ukraine labeled Austrian banking group Raiffeisen a "war sponsor" for refusing to exit Russia. Under Gewessler's new proposals, Austrian gas firms would have to show they are gradually increasing the share of non-Russian flows in their supplies. The government will also commission an independent study evaluating the costs of terminating the long-term contract between Russia's gas export giant Gazprom and Austria's partly state-owned energy firm OMV. The problem is that ending the long-term contract — the contents of which are confidential — would likely trigger an early termination fee worth "more than €1 billion," said Florian Stangl, an Austrian energy lawyer at NHP Rechtsanwälte. The "only possibility" to avoid this would be to pass "a clear law" that bans Russian gas imports generally or ends the specific contract, he said, though even this would "probably" lead to Gazprom launching an arbitration case against OMV.
