greenhouse gas emissions energy demand and land use associated with omnivorous pesco vegetarian vegetarian and vegan diets accounting for farming practices
Sustainable Production and Consumption, 2020Co-Authors: Anaelle Rabes, Louise Seconda, Brigitte Langevin, Benjamin Alles, Mathilde Touvier, Serge Hercberg, Denis Lairon, Julia Baudry, Philippe Pointereau, Emmanuelle KesseguyotAbstract:Abstract In the present context of environmental damages, Food systems constitute one of the key burdens on the environment and resources. Dietary patterns emerge as a main leverage to preserve a healthy environment. The aim is to compare the environmental impacts of different diets with different levels of animal product consumption, while accounting for the type of farming systems (organic or conventional) of the Food consumed. Dietary environmental impacts of the diet of 29,210 NutriNet-Sante participants were estimated using databases developed within the BioNutriNet project. Four diets, differing from their Animal-Based Food proportion, were studied: omnivorous, pesco-vegetarian, vegetarian, and vegan. Three individual environmental indicators were assessed (greenhouse gas emissions, cumulative energy demand and land occupation) and combined in one aggregated partial score (pReCiPe, partial ReCiPe). Means of these indicators adjusted for energy intake were estimated across diet groups using covariance analysis. About 95% of the study sample was omnivorous. Organic consumption was much higher among non–omnivorous than other groups. The pReCiPe were 64%, 61%, and 69% lower for diet of pesco-vegetarians, vegetarians and vegans respectively, in comparison to the omnivorous diet. Regarding the three individual environmental indicators included in the pReCiPe index, the same trend was observed but trade-offs exist in organic with cumulative energy lowered and land occupation augmented. A positive link between animal-sourced Food consumption and total environmental impact was observed in this large sample of French adults. By far, omnivorous had the highest-level of greenhouse gas emissions, cumulative energy demand and land occupation while vegan diets had the lowest. Further research on environmental indicators distinguishing farming practices is needed to allow a more comprehensive evaluation of the impact.

consumer liking and willingness to pay for high welfare animal based products
Trends in Food Science and Technology, 2010Co-Authors: Fabio Napolitano, Antonio Girolami, Ada BraghieriAbstract:Consumers currently tend to rely more and more on extrinsic cues and credence characteristics, including process characteristics (e.g. the way animals are raised), to form their expectations about Animal-Based Food products. This review shows that if expectations are negatively disconfirmed, the hedonic ratings and consumer willingness to pay move towards the expectations induced by information on animal welfare according to the sensitivity of different groups of consumers. The combination of reliable animal welfare monitoring and effective labelling of Animal-Based products may then help meeting the increasing demand for animal welfare-friendly products while sustaining the welfare of the animals.

effect of information about animal welfare on consumer willingness to pay for yogurt
Journal of Dairy Science, 2008Co-Authors: Fabio Napolitano, C Pacelli, Antonio Girolami, Ada BraghieriAbstract:This study aimed to verify whether consumers confirm their willingness to pay extra costs for higher animal welfare standards in a situation where a potential purchase performed by consumers, such as the Vickrey auction, is used. A 104-member consumer panel was asked to rate its willingness to pay (WTP) for plain and low-fat yogurts in 3 information conditions: tasting without information (blind WTP), information about animal welfare without tasting (expected WTP), tasting with information about animal welfare (actual WTP). Information was provided to the consumers under the form of labels indicating the level of animal cleanliness and freedom of movement (5-point scale, from poor to very good). Consumers were influenced by information about low standards of animal welfare (low cleanliness and low freedom of movement) and moved their willingness to pay in the direction of their expectations. However, the discrepancy between expectancy and actual WTP was not totally assimilated, indicating that WTP was also expressed in relation to other aspects (e.g., the sensory properties of the products). Conversely, the information concerning high standards of animal welfare (high cleanliness and high freedom of movement) was able to affect expectancy but had an effect on actual WTP only when the most acceptable yogurt was offered to the consumers. In the case of discordant information on animal welfare, partly indicating high levels of welfare (freedom of movements) and low levels of welfare (cleanliness), expected WTP was always lower than blind WTP. However, when the least acceptable product was presented, they completely assimilated their actual WTP to the expectations. Conversely, with the most acceptable yogurt, no assimilation occurred and sensory properties prevailed in orienting consumer WTP. Within each product, consumers expressed a higher WTP for products with labels indicating high welfare standards as compared with yogurts with labels reporting intermediate and low welfare standard. These results show that information about animal welfare, if given to the consumers, can be a major determinant of consumer WTP for Animal-Based Food products. However, information about high standards of animal welfare should be paired with products presenting a good eating quality.
