New trend, food to be analyzed by climate impact
(CNN) - A new study suggests adding climate impact information to menus, may encourage people to eat more climate-friendly foods. How obnoxious is that?
The medical journal Jama published the study Tuesday.
More than 5,000 adults participated in randomized clinical trials where researchers asked them to pick an item from one of three menus.
Two of the menus had high climate impact labels, filled with red meat.
Researchers also found people were more likely to opt for a more sustainable meal.
Furthermore, they say red warning labels were most effective.
