Starbucks is under a boycott call from the US Organic Consumer's Association over its involvement in efforts to overturn Vermont's GMO labelling laws.
Although Starbucks is not directly involved, it is a member of the Grocery Manufacturers Association (GMA), which was party to a lawsuit in 2014 against the state of Vermont intended to overturn Vermont’s GMO labeling law. An article in Reuters, cited by the campaign stated:
Internal GMA documents filed last year as part of a lawsuit in Washington State revealed [GMA] members contribute to a "Defense of Brands Strategic Account" designed "to help the industry fund programs to address the threats from motivated and well financed activists" and to "shield individual companies from criticism for funding of specific efforts.
When asked by Reuters if Starbucks has contributed to this “special” account, Starbucks did not respond. OCA is calling for a boycott of Starbucks until the company "stop paying dues to GMA". It has also been heavily criticised by Ethical Consumer over corporate tax avoidance, and has further boycott calls against it over the issue.
