A systematic review on how environmental sustainability and social responsibility food labels influence consumers' food choices and purchasing decisions.
Synthesis in Public health nutrition, 2026. 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
objectiveIn a world under a triple planetary crisis of climate change, biodiversity loss and pollution, this study aimed to evaluate the types, features and impacts of environmental sustainability and social responsibility food labels on consumers' choices and purchasing decisions.
designA systematic review encompassing three electronic databases was conducted. The initial search was conducted in May 2022 and updated in July 2025, identifying 364 studies. After screening, forty-one studies were included. Data were extracted using a standardised form and analysed by topic.
settingStudies included were conducted in various consumer and market settings, primarily focusing on packaged food products.
participantsThe studies represented a range of consumers across demographic and geographic contexts, but mostly focused on Western Europe, the US and other high-income countries.
resultsMost studies were experimental ('choice experiments') and evaluated purchasing intentions. Environmental sustainability labels generally elicit positive consumer responses, with high preferences for organic and animal welfare claims. Consumers often desire additional information to better understand label meanings. While some evidence supports the influence of environmental sustainability labels on consumer choices, their impact on actual purchasing behaviour remains mixed. Research on social responsibility labels is notably limited.
conclusionsThere is insufficient evidence to determine the real-world impacts of environmental sustainability and social responsibility labels on food choices. Future studies could focus on purchasing behaviours in real-life consumer interactions with labels, the impacts of the exposure to varying levels of information and a potential integration of domains. Given pressing social and environmental challenges, integrative strategies are required to develop labels that effectively guide consumers toward healthier, sustainable, and socially responsible food options.
