Why is KazMunayGas planning to pay its share of the $5 billion Kashagan environmental fine while its foreign partners are not?

KazMunayGas intends to comply with a June 19 ruling by an Atyrau-based Kazakh court that upheld the 2.356 trillion tenge (approximately $5 billion) environmental fine for excessive sulfur storage at the Kashagan field, and it has informed both the Kazakh government and its partners of this decision; in contrast, its foreign partners—including Shell, ExxonMobil, Eni, TotalEnergies, Inpex, and CNPC—deny violating environmental rules, reject the fine and its underlying allegations, and are contesting it through international arbitrations (ICSID and UNCITRAL), with the UNCITRAL tribunal having issued a restraining order prohibiting Kazakhstan from enforcing the fine during the arbitration proceedings.

What enforcement consequences could Kashagan’s operator and stakeholders face if the fine remains unpaid after July 20?

After July 20, enforcement measures may be taken against Kashagan’s operator, the North Caspian Operating Co. (NCOC), and its stakeholders, including 'the withholding of an additional enforcement sanction of 10% of the amount collected', according to Kazakhstan’s Justice Ministry; the June 19 court ruling has entered into force and is subject to voluntary execution until that date, after which mandatory enforcement becomes possible under Kazakh law.
