Tuna, in tomato sauce, canned
Climate footprint in kg CO2e/kg
Detailed background data
It has been assumed that the food processing industry is located in Denmark. Based on canned tuna products, declaring 65% tuna and 35% sauce (Open food Facts 2020o). The sauce is coarsely modelled based on a commercial tomato sauce (Open Food Facts 2020n). Inputs for manufacturing are assumed as in canned tuna from Hospido et al. (2006). Retail is modelled assuming the following storage: Ambient. See more details as well as literature references in the methodoly report on: www.denstoreklimadatabase.dk.
Data on inputs and outputs of the food processing industry is modelled using: Open Food Facts (2020n); Open Food Facts (2020o); Hospido et al. (2006). Data for this species is based on data for salmon aquaculture because it is currently fished to its carrying capacity and wild catch cannot be increased.
