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. OCA is calling for a boycott of Starbucks until the company "stop paying dues to GMA".
The Lakota People's Law Project (LPLP), an indigenous rights organisation, has also called for a boycott of the company over its partnership with Nestlé, "undoubtedly one of the world's most environmentally-unsound corporations". In 2018, Starbucks signed a $7.15 billion deal with Starbucks - the third largest transaction in Nestle's 152-year history - which allows the company to sell Starbucks branded products.
Starbucks has also been heavily criticised by Ethical Consumer over corporate tax avoidance, and has further boycott calls against it over the issue.
