the relevant Regional Fisheries Management Organisation (RFMO), caught by fishing vessels which do not ban shark finning, or caught by vessels which do not have a European Union sanitary agreement. However several of these claims have been disputed by other bodies. In August 2008, John West was assessed by conservation group Greenpeace as selling the least sustainable tinned tuna in the UK in its Tuna League. It was also criticised for indiscriminate use of destructive fishing methods leading to the decimation of turtle and shark populations, and Greenpeace noted that John West failed to show sufficient care in selecting healthier fish stocks. In 2011, the company committed to source all of its tuna through a combination of pole and line and purse seine FAD-free (fish aggregation devices) sustainable catch methods by the end of 2016. The first step towards this was the launch of pole and line tuna in September 2011. By 2016 the company had reneged on this promise, with just 2% of its fish caught using pole-and-line. The estimated 98% of John West's tuna caught using methods harmful to the environment or to other species such as dolphins, lead the company to last place again in Greenpeace's 2015 tuna sustainability ranking. John West stated that "Quite simply, there is no longer enough pole and line tuna available to meet global demand ... we have found it extremely difficult to increase the proportion of John West pole and line tuna that we can provide". In a rebuttal, Greenpeace pointed out that it was the lack of investment from large fleet-owners and processors like John West that result in this situation, and that John West had felt it achievable in 2011. Traceability John West is the only UK and Ireland canned seafood manufacturer to wholly own a fleet of vessels which ensures it has visibility of its entire fishing supply chain. In October 2011, following the above controversies, the company advertised that its supply chain would be made fully transparent for its consumers by allowing "100% tracing" by the public of each can of fish to the original boat and location of catch, using a ‘Can Tracker’ on the company's website. The application enabled John West consumers to track the exact source of the fish in their can including the ocean and even the boat that made the catch. However, in October 2015, John West was accused by conservation group
