Implementing climate menu labels in university settings: a narrative review.
Review in Frontiers in nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Global food systems are a major contributor to climate change, accounting for more than 30% of greenhouse gas emissions (GHGEs). This review synthesizes current evidence on the potential of climate labels (which we define as labels attached to menus or food items with climate impact information) in university dining settings to encourage climate-friendly food decisions. In April 2024, we searched Scopus, ProQuest, Web of Science, and PubMed using developed terms related to climate labels and universities. We identified 280 articles and narrowed down the review to 14 articles based on study setting, language, and scope. Of the 14 studies, 86% (12 articles) observed a decrease in the consumption of foods researchers classified as high emissions, 60% (8 articles) observed a decrease in the consumption of foods classified as medium-emission foods, and 63% (9 articles) observed an increase in the consumption of foods classified as low-emission food. Effects varied by gender and age, with women appearing to experience a greater response to the climate labels, but no observable differences were evident by ethnicity or socio-economic class. Studies that supplemented climate labeling initiatives with sales promotions or resources encouraging consumers to conduct their own emission research also saw favorable results. The studies suggest a small yet detectable shift in consumer behavior in response to climate labels in university dining settings; however, further research is needed on: (1) improving climate label effectiveness, (2) the effect of climate labels among different demographic attributes (e.g., income, ethnicity), and (3) the long-term and spillover effects of the labels on the healthiness of consumer diets, and institutional sourcing practices.
