Global food systems are currently challenged by unsustainable and unhealthy consumption and production practices. Food labelling provides information on key characteristics of food items, thereby potentially driving more sustainable food choices or demands. This review explores how consumers value three different elements of sustainable diets: Comparing consumer response to nutrition information on food labels against environmental and/or social responsibility information. Six databases were systematically searched for studies examining consumer choice/preference/evaluation of nutrition against environmental and/or social responsibility attributes on food labels. Studies were quality assessed against domain-based criteria and reported using PRISMA guidelines. Thirty articles with 19,040 participants met inclusion criteria. Study quality was mixed, with samples biased towards highly-educated females. Environmental and social responsibility attributes were preferred to nutrition attributes in 17 studies (11 environmental and six social), compared to nine where nutrition attributes were valued more highly. Three studies found a combination of attributes were valued more highly than either attribute in isolation. One study found no significant preference. The most preferred attribute was organic labelling, with a health inference likely. Consumers generally have a positive view of environmental and social responsibility food labelling schemes. Combination labelling has potential, with a mix of sustainable diet attributes appearing well-received.

Research suggests that eating vegetables benefits both human health and the environment. However, in the UK, very few people are eating enough vegetables. This is contributing to the global burden of diet‐related disease and associated costs, as well as undermining the possibility of a sustainable UK food system. The Peas Please initiative was launched in 2017 to encourage organisations and businesses across the food system to pledge their commitment to helping the British public increase their vegetable consumption. Since the implementation of the Peas Please initiative 95 organisations have pledged to support Peas Please and, at the time of writing, an additional 89.9 million portions of vegetables have been grown, served and sold by pledgers. This article describes the Peas Please initiative and its rationale, highlights some of the key outcomes of the programme, and outlines next steps for increasing commitment to the programme.
