![]() ![]() The authors based the high/low impact climate categories on evidence that beef has high climate impact compared to other proteins. The “high climate impact” labels for all beef burger choices were red. The “low climate impact” labels for vegetarian, chicken, or fish menu items were green. ![]() The study was fielded from March 30 to April 13, 2022, and included 5,049 nationwide participants. Less consumption of red meat also would also help to lower greenhouse gas emissions which would help reduce climate change because beef production is the largest contributor of greenhouse gas emissions in the food and agriculture sector. Red meat consumption has been linked to health problems such as colorectal cancer, stroke, type 2 diabetes, and other illnesses. Using labels on menus has long been seen as a potential approach for promoting healthful and sustainable food options.įor their study, Wolfson and her co-authors wanted to test how signaling climate change impacts of fast food menu items might prompt people to opt for less red meat. “These results suggest that menu labeling, particularly labels warning that an item has high climate impact, can be an effective strategy for encouraging more sustainable food choices in a fast food setting,” says study lead author Julia Wolfson, PhD, associate professor in the Department of International Health at the Bloomberg School. The study was published online December 27 in JAMA Network Open. M enus that included “low climate impact” labels increased non-beef choices, such as a chicken sandwich or a salad, by about 10 percent more participants than those in the control group. Menus with a “high climate impact” label on burgers increased non-beef choices by 23 percent compared to the control group. One group of participants received a menu with non-red meat menu items such as chicken sandwiches labeled “low climate impact.” Another group received a menu with red meat items-burgers-labeled “high climate impact.” A third control group received menus with QR codes on all items and no climate labels.īoth the high and low climate impact labels markedly reduced red meat selections compared to the control group, with the high impact labels having a strong effect. The study was led by a researcher at the Johns Hopkins Bloomberg School of Public Health.įor the study, more than 5,000 online participants were shown a sample menu resembling a fast food menu and asked to choose a single item for dinner. A new study has found that including climate impact labels on a sample fast food menu influenced participants’ food choices in favor of more climate-friendly items. ![]()
