Kind: research · Impact: low

## In brief

- A new study suggests that advertising both eco-friendly ingredients and sustainable packaging can make a product less appealing to some shoppers.
- People who care a lot about buying green rated a product higher when its green claims were not stacked, according to the article's opening (the full result is not in the source excerpt).
- The source is a single Earth.com article; the study itself was not reviewed here.

## Why it matters

Brands often add multiple green claims to a product, assuming more is better; this research suggests stacking claims can backfire with some shoppers, which matters for marketing choices and for how consumer sustainability messages are designed.
