PARIS: TotalEnergies’ chief executive said Wednesday that his company could not stop buying Russian natural gas in retaliation for Moscow’s invasion of Ukraine, saying it would force a partial economic shutdown in Europe.

The French energy giant had announced Tuesday that it would stop buying Russia’s oil and petroleum products by the end of this year, the latest of several multinationals to halt or curtail their operations in the country.

But CEO Patrick Pouyanne said ending its natural gas purchases from Russia would effectively hand over billions of euros to Russian investors.

Unlike oil, which can more easily be shipped for sale anywhere in the world, natural gas is often supplied via pipelines directly to individual countries and clients.

“I know how to replace this oil and diesel fuel,” Pouyanne told RTL radio, but “with gas, I don’t know how to do it.”

“I don’t know how to replace it, there isn’t any other available, and I have 25-year contracts that I can’t get out of,” he said.

Unless European governments impose sanctions on Russian gas, which would allow companies to declare force majeure to break contracts, pulling out of existing deals would require TotalEnergies to pay billions in penalties to its Russian partners.

Pouyanne also warned that European economies would pay a heavy price.

“Without Russian gas, you stop part of the European economy... If we stop Russian gas we know that in winter 2023 we have a problem, in January we’ll have to ration gas use, not for households but probably for industry,” he said.
