The current food-system is highly unsustainable as it is responsible for up to 50% of all anthropogenic environmental pressure. Therefore, there is a need to transform the current food-system, in particular the demand-side. Cities form the agglomeration of food consumption with limited capacity for food production. Addressing urban consumption and the inherent environmental impacts are considered key factors for climate change mitigation. In order to develop sustainability strategies for a city, a baseline assessment of urban food consumption and environmental impacts is required. A bottom-up approach is suggested to be suitable for consumption-based accounting of urban food-systems. However, there is no consensus on this approach nor the implementation of it due to a lack of modelling experience and data on urban food-consumption.
