The carbon impact of livestock farming, transportation to Ljubljana and its packaging remains high.Challenge vision
The city of Ljubljana is surrounded by farms which focus on vegetable production and sell their produce daily on the local market. The carbon impact of such farming and transportation is low compared to the carbon impact of livestock farming.
However, meat and meat products form an important part of the diet of the Slovenian population in general and the citizens of Ljubljana.
