In its second annual ranking of Canadian canned tuna brands, Greenpeace gave a passing grade to almost half of the country’s 14 major brands,  the NGO said Monday.

“We have seen some positive change in tuna markets around the world and now we’re seeing Canadian canned tuna brands step up and commit to sourcing tuna more responsibly,” says Sarah King, Greenpeace Canada Oceans Campaign Coordinator.

Greenpeace’s 2012 canned tuna ranking assessed and scored companies based on the sustainability and equitability of their tuna procurement policies and practices.
