UK convenience retailer The Co-op is unveiling a new tuna sourcing policy that extends its own commitments and also holds big brands to account.

The company has widened its tuna sourcing policy to include branded canned tuna suppliers Princes and John West.

As part of the decision, The Co-op has set a deadline of the end of 2017 for tuna under these brands to be sourced from fisheries improvement projects (FIPs) working towards the Marine Stewardship Council (MSC) standard.

The Co-op’s deadline to branded suppliers is part of its revamped tuna commitments.
