JAMA: Climate-impact labels on fast food could alter purchasing habits

In a survey of 5,000 adults conducted by the Journal of the American Medical Association (JAMA), 23 percent said that a label warning of the environmental impact of red meat would deter them from buying such products at fast-food restaurants. “If, at a population level, we made even just some minor shifts to the way we make our food choices, substituting some beef items for less impactful choices, there can be a really measurable effect on climate change,” said Julia Wolfson, lead author of the study.
