UK retail giant Tesco is taking a new “holistic approach” to its tuna sourcing strategy, going one step further from solely relying on certification schemes to ensure whole marine ecosystems are maintained in a healthier, more productive way.

In partnership with the World Wide Fund for Nature (WWF), the supermarket giant is advocating for a “Seascape” approach to marine sustainability, similar to the landscape approach it adopted in the Tesco UK Zero Deforestation Soy Transition Plan, and the climate approach in the Tesco Group Renewable Electricity Transition Plan.
