Explaining the Differences between the Environmental Impacts of 44 French Artisanal Cheeses

Cheese production causes significant environmental impacts, which have to be reduced. In France, a lot of different cheeses are available, made from different milks but also from different cheese technologies. The goal of this study was to understand the origin of the environmental impact variation between cheeses made from different technologies and milks and produced using different ripening practices. To do so, the environmental impacts of 44 different types of French artisanal cheese, all produced under protected designation of origin (PDO) labels, were assessed using the life cycle assessment. Cheese technologies were fully described and two ripening scenarios were investigated. Results show that the differences of environmental impacts between cheeses mainly come from: the milk type (cow, goat, or sheep), the milk amount needed to produce one kilogram of cheese, the energetic performance of the ripening room, and the ripening time. Such results could be useful to cheesemakers to identify the origin of the environmental impacts of their products and to implement effective actions to reduce them. According to the results, innovations leading to the reduction in electrical consumption during ripening are interesting to explore in order to increase the environmental performance of a cheese.

Automated summary

The goal of this study was to understand the variation in environmental impact between cheeses made with different technologies and milks. The results show that the main factors contributing to the differences in environmental impacts are milk type, milk amount, energetic performance of the ripening room, and ripening time.
