Ecological Economics, 44(2-3), 293-307. 'Food miles' are measured in tonne-kilometers, representing the transport of one tonne of goods by a given transport mode (road, rail, air, sea, inland waterways, pipeline, etc.) over a distance of one kilometer.

The ecological footprint considers the pressure on ecosystems resulting from human activities, the land footprint quantifies land occupation, the energy footprint measures energy consumption, and the biodiversity footprint focuses on the impact on biodiversity FLW is prevalent throughout various stages of the food supply chain, contributing
Food supply has been the central issue of human development for millennia and has become increasingly critical in an urbanizing world. However, the environmental footprints and associated mitigation strategies of food consumption have rarely been comprehensively characterized at urban or regional scales. Here, we analyze the water, carbon, reactive nitrogen, and phosphorus footprints of food 1. Introduction. Food is a basic need for humans but the way in which much of it is produced, distributed, and consumed, is not sustainable. Challenges include among other things, biodiversity loss, climate change, environmental degradation, diet-related diseases, and unequal access to food (Schneider et al., Citation 2023).A 'food system' perspective helps to better understand the root Finally, supply chains account for 18% of food emissions. This includes food processing, distribution, transport, packaging, and retail. Transport tends to be a small part of a food's carbon footprint. Globally, transport accounts for just 5% of food system emissions. Most of food's emissions come from land use change and emissions from
