France is not known to be friendly towards vegetarians as lunches at public schools must contain a "minimum of 20% of meals containing meat and 20% containing fish, and the remainder containing egg, cheese, or offal. However, under a law called "loi Egalim", which passed in 2018 and came into effect in November 2019, all French schools are required to serve at least one meat-free meal a week. In September 2020, 73% of French nurseries and elementary schools offer at least one meat-free meal a week, according to a recent investigation by Greenpeace.
