Is there any literature that actually states labelling items with palm oil vs vegetable oil actually makes a difference in consumer behaviour? In my small window of the world, I feel like the issue with palm oil is not well known.
"Mandatory labelling of palm oil will help put pressure on food companies to start using sustainably-produced palm oil." [0]
There seems to be disagreement about what sustainable palm oil entails or how sustainable it actually is [1], so would be good to see this claim backed up with research.
