In October 2017 Ethical Consumer searched the A G Barr’ website for a policy on genetically modified ingredients and the use of genetically engineered animal feed. No information was found.

A G Barr's FAQ section on its website stated some Rubicon flavours contained skimmed milk. As the products were not labelled organic, it was likely to be from animals fed a genetically modified diet. In June 2017 the British government website www.food.gov.uk stated that the EU animal feed industry imported 70% of its maize, soya and rapeseed requirements; that "almost all" of the soya from the major producers Brazil, Argentina, Paraguay and the USA was genetically modified and that "much of" the maize imported from the USA was genetically modified.

The company therefore lost half a mark in the Controversial Technologies category.

In November 2020, Ethical Consumer viewed A.G. Barr’s family tree on the corporate database hoovers.com. The family tree listed one subsidiary (Group Rubicon Ltd) based in Jersey, considered by Ethical Consumer to be a tax haven at the time of writing. All the other subsidiaries were in the UK.
The subsidiary was also a holding company, and therefore at high risk of being used for tax avoidance. As this was the only subsidiary based in a tax haven, however, A. G. Barr was not marked down in this category.
