Food Consumption and Climate
Change ?

Swedish Defence Research Agency
Which gases have caused climate
change?
Emissions of greenhouse gases can be
attributed to the final consumers

Emissions of CO2 from the average Swedish
household’s consumption with a life-cycle perspective
The global map of Swedish CO2
consumption related emissions
12 tonnes per capita instead of 6 !
Life spans of products are complex
and geographically separated
Sushi consumed in Sweden:
- fishing outside Chile
- faming salmon in Norway
- flying salmon to Taiwan
- shipping sushi to Europe
- selling sushi in Stockholm
kg carbondioxide ekvivalents, 100-years
Greenhouse gas emissions in products
life spans can be calculated and
visualised

GHG emissions from two meals same amount of food
MenuToolan interactive tool for climate
friendly menu planning
Information project financed by Formas
Carried out by KTH, Göteborg University and
Energivision
What is MenuTool?
Information about LCA greenhouse gas
emissions and energy use for 170 food items
Information about the permissible
environmental space (energy and greenhouse
gases)
Information about the nutritional content of
foods (seven parameters)
Enables menu planning with individual
feedback about environmental and nutritional
impacts =enter your recipie and see the results
Example of results: GHG gases per meal
compared with the environmental space
Other examples: energy inputs for each
ingredient (also available for GHG gases)
Challenges for eating climate
friendly in the North?
Meat is a symbol of power and potence
Carbon labelling is lacking
Diets must be culturally acceptable
Missed opportunties for the South?
