Global Tuna Alliance (GTA)

The Global Tuna Alliance (GTA) is an independent group of retailers and supply chain companies working to ensure that tuna meets high standards for environmental performance and social responsibility. Members work collaboratively to find industry-wide solutions to improve the sustainability of the tuna sector and support GTA campaigns.

In 2021, the ALDI SÜD and ALDI Nord Groups partnered with the Global Tuna Alliance (GTA) to support the sustainable development of their supply chains. As a partner, we commit to:

  • Realising harvest strategies for tuna fisheries
  • Avoiding Illegal, unreported and unregulated product
  • Improving traceability and environmental sustainability
  • Progressing work on human rights in tuna fisheries
  • Implementing the objectives laid out in the World Economic Forum’s (WEF) Tuna 2020 Traceability Declaration

This work falls within the GTA's strategic pillars of Blue Resilience (environmental sustainability), Blue Community (fair labor conditions), and Blue Integrity (supply chain transparency and traceability) to help conserve diverse tuna resources and the marine industry for generations to come.

Tuna stocks around the world are under increasing strain from poor management. We are committed to responsibility and sustainability when sourcing our own-label fish products. It is our goal to increase the share of responsibly sourced products in our fish and seafood range. Working with the GTA will help us reach this goal.
