Scarlett Johansson stepping down as Oxfam ambassador over SodaStream deal "Scarlett Johansson has respectfully decided to end her ambassador role with Oxfam after eight years," the statement said. She and Oxfam have a fundamental difference of opinion in regards to the boycott, divestment and sanctions movement. She is very proud of her accomplishments and fundraising efforts during her tenure with Oxfam. Earlier this month, "The Avengers" and "Her" actress signed on as the first global brand ambassador of SodaStream International Ltd., and she is set to appear in an advert for the at-home soda maker during the Super Bowl on Feb. 2. In response to the criticism, Johansson said last week she was a "supporter of economic cooperation and social interaction between a democratic Israel and Palestine." Oxfam took issue with Johansson, noting it was "considering the implications of her new statement and what it means for Ms. Johansson's role as an Oxfam global ambassador." Johansson had served as a global ambassador for Oxfam since 2007, raising funds and promoting awareness about global poverty. In her role as an Oxfam ambassador, she traveled to India, Sri Lanka and Kenya to highlight the impact of traumatic disasters and chronic poverty. Oxfam representatives did not immediately return messages seeking comment.
