Impact of transportation on food systems


Transportation has emerged as a key link in food supply chains. When the food supply chain is considered, global food-miles correspond to about 3.0 GtCO2e, indicating that transport accounts for about 19% of total food-system emissions (stemming from transport, production and land-use change). Global freight transport associated with vegetable and fruit consumption contributes 36% of food-miles emissions—almost twice the amount of greenhouse gases released during their production. To mitigate the environmental impact of food, a shift towards plant-based foods must be coupled with more locally produced items, mainly in affluent countries. How can individuals reduce their emissions from transport? Please read more in Hannah Ritchie (2023).
