The tuna in the Greenseas range is Skipjack tuna (Katsuwonus pelamis). Skipjack is a type of tuna that is widely recognised as having sustainable stocks and as an abundant, fast-growing type of tuna.

Tuna in the Greenseas range is sourced from the Western and Central Pacific Ocean, FAO Area 71.

Stocks of skipjack tuna in FAO Area 71 (and globally) have been assessed as being at sustainable levels that are not overfished. This assessment is made in the 'Status of the World Fisheries for Tuna. March 2024 ISSF Technical Report 2024-02 published by the International Seafood Sustainability Foundation.

Greenseas tuna is sourced using FAD-free purse seine fishing methods. This means that the tuna is caught by purse seine fishing methods (a method of open-ocean fishing using a net to target schools of fish like tuna) without the use of fish aggregating devices (or FADs). FADs are man-made floating objects used to aggregate fish which can result in higher levels of bycatch of non-targeted fish or other marine species that may be caught unintentionally. No FADs are used to catch tuna in the Greenseas range.

Greenseas tuna is sourced from longstanding, reliable suppliers who are contractually obligated to source and use only skipjack tuna caught using FAD-free methods, with sourcing supported by measures for FAD-free traceability from fishing vessel to the Greenseas product. This means that the FAD-free skipjack tuna used in the Greenseas range may be caught, for example, via the FCF Tuna Sustainability Program (FSP) or caught in the Western and Central Pacific Ocean (FAO Area 71) by registered fishing vessels during the mandated FAD-Free ban between July and September each year, underpinned by traceability measures from vessel to product.

As part of Greenseas Commitment to responsible sourcing, no tuna used in the Greenseas range is sourced from vessels engaged in illegal, unreported or unregulated (IUU) fishing activities.

Greenseas (along with its longstanding suppliers, from whom it sources its Greenseas tuna) are certified Dolphin Safe suppliers under the Earth Island Institute's International Monitoring Program, which aims to eliminate injury and death of dolphins and other marine mammals and to reduce bycatch.
