Protect the ocean ecosystems that give us the finest fish
An omakase dinner is about 2 to 7 kg of CO₂e, food only, and much of that is the flight from Tokyo. The bigger story is the ocean: which species, how it was caught, and what came up with it.
The footprint, plainly
Threatened species
Southern bluefin tuna and Japanese eel are listed as Endangered by the IUCN. Pacific bluefin has recovered above its rebuilding target but is still heavily fished.
Flown in
Much of the fish at a New York omakase is flown from Tokyo. For one dinner the flight can add up to 2.7 kg of CO₂e, often more than catching the fish.
Bycatch
About 5% of the global tuna catch is discarded, and longlines account for 64% of that discarded weight.
