Johansson appeared in an ad (see below) for the Israeli-based soft drinks firm which was due to be screened during the Super Bowl broadcast in the US, but was banned by broadcaster Fox due to the inclusion of the line "Sorry, Coke and Pepsi".
Oxfam, which had used Johansson as an ambassador since 2007, subsequently came under fire from pro-Palestinian campaigners over the fact that SodaStream has a factory in a disputed Israeli settlement in the West Bank territory.
The charity issued a statement that said it was "considering the implications" of Johansson’s partnership with SodaStream,, citing "a fundamental difference of opinion" over the matter.
The Observer, Johansson said: "I stand behind that decision."
She added: "I was aware of that particular factory before I signed. And it still doesn't seem like a problem – at least not until someone comes up with a solution to the closing of that factory and leaving all those people destitute."
Johansson said that the argument against the SodaStream factory was far from clear cut. "I think that's something that's very easily debatable," she said.
"In that case, I was literally plunged into a conversation that's way grander and larger than this one particular issue. And there's no right side or wrong side leaning on this issue."
