2025 Pledge towards Sustainable Tuna (25PST)


During 2019-20, through a collaborative agreement with the World Economic Forum (the Forum), the GTA implemented the objectives laid out in Forum’s Tuna 2020 Traceability Declaration (TTD).

 The TTD was a non-legally binding declaration that grew out of a dialogue among governments, companies and civil society, spurred by the President of the UN General Assembly’s Ocean Sustainable Development Goals (SDGs) Summit in June 2017. The Declaration was endorsed by 66 leaders of the world’s biggest retailers, tuna processors, marketers, traders and/or harvesters, with the support of 21 influential civil society organizations, and 6 governments. The entities who endorsed the Tuna 2020 Traceability Declaration pledged concrete actions and partnerships to demonstrate their commitment to implement the TTD and Action Agenda. The TTD concluded in December 2020.

The Forum, Friends of Ocean Action and the GTA are convening responsible businesses, governments and civil society organizations around a refreshed commitment, which will be known as the 2025 Pledge towards Sustainable Tuna (25PST). The 25PST will build on the momentum generated by the TTD, and the GTA’s achievements through its Partners. The 25PST was formally launched in March 2021 and runs until December 31st 2025.

Signatories’ Pledge

By signing on to the 25PST, signatories are pledging to making demonstrable progress on the three commitments. Each signatory, depending on their sector and current practices, pledges to make demonstrable progress on their selection of the list of actions in annex 1, and other improvements as they see fit, while all signatories pledge to complete the minimum commitments below:

Commitment 1: Transparency & Traceability

Transparency is critical to ensure legal, environmentally sustainable and socially responsible supply chains[1].

We pledge to continually improve the traceability systems in our tuna supply chains to enable greater transparency, and to advocate for improved transparency in tuna fisheries.

Signatories commit to all tuna products[2] in their supply chains being fully traceable to the vessel and trip[3] dates, and that this information can be transparently shared by the end of 2025.

 The Port State Measures Agreement (PSMA) is a binding international agreement the main objective of which is to prevent deter and eliminate IUU fishing yet PSMA is not yet widely ratified across tuna fisheries. Signatories commit to advocating in their supply chains for the ratification, and implementation, of PSMA so that they will in future be in a position to give preference to sourcing tuna that have been landed or transhipped at ports that are implementing Port State Measures (PSMs) that are aligned with the requirements of the PSMA.

 Signatories commit to conduct regular due diligence of PSMs implementation for ports where product is being landed, with particular attention to ports that are processing vessels operating in fisheries associated with a higher risk of IUU activities.

 Signatories will advocate for improved transparency in tuna fisheries (this could be achieved through collaborative advocacy from organisations like the GTA.)

Commitment 2: Environmental Sustainability

Environmental sustainability of fisheries is critical to ensuring fishing is at a level that can, based on current scientific knowledge, continue indefinitely whilst the fish populations remain productive and healthy. To keep the ecosystem healthy, it is also important that fishing activity minimises negative impacts on other species and habitats, and well managed fishing operations have pre-determined limits at which they are concurrently adaptable to changing environmental circumstances and new scientific learning; the achievement of these aspects is crucial to effective harvest strategies.

We pledge to source from fisheries that meet the goals of environmental sustainability as outlined above, or are working towards them in a structured, time-bound process; and to advocate for comprehensive harvest strategies in tuna fisheries.

Signatories will publicly commit to sourcing 100% of tuna products from fisheries with a Global Sustainable Seafood Initiative (GSSI) recognized certification, or that are in credible, comprehensive Fisheries Improvement Projects (FIPs) by the end of 2025.

Signatories will advocate for the development and implementation of effective harvest strategies in tuna fisheries (this could be achieved through collaborative advocacy from organisations like the GTA as well as advocacy by individual partners to the states involved in the tuna supply chains.)

Commitment 3: Social Responsibility

We uphold the fundamental human rights[4] as outlined in the UN Declaration of Human Rights and recognise there are human rights risks in tuna supply chains. We recognise both the role of businesses to respect human rights as outlined in the UN Guiding Principles, and the importance of Governments protecting human rights. Governments and businesses both have an important role to play in ensuring that those affected by human rights breaches have access to remedy. The ratification and adoption of relevant ILO conventions is critical to implement decent working conditions for all workers in fishing.

We pledge to complete effective due diligence regarding human rights risks in our tuna supply chains and advocate for implementation of international legislation to safeguard these rights.

Signatories commit to sharing their company policies on human rights and specifically with their supply chain stakeholders.

By the end of 2021, signatories will commit to establish a baseline regarding human rights due diligence and processor and vessel level  practices in tuna supply chains (see GTA Social Responsibility Toolkit for guidance.)

Signatories commit to implement due diligence processes and timebound improvement targets by the end of 2025 aimed at adherence to relevant ILO conventions.

Signatories will advocate for improved social responsibility in tuna fisheries (this could be achieved through collaborative advocacy from organisations like the GTA.)


While all signatories commit to making demonstrable progress on the three commitments above, specific actions will depend on the point a company is in the supply chain, and its baseline conditions. Beyond the minimum commitments, each signatory will make additional improvements best suited to their circumstances. Annex 1 contains other improvements signatories can make to achieve the goal of moving towards more transparent, environmentally sustainable and socially responsible tuna supply chains.


[1] Transparency is also enabled by the certification and due diligence requirements in the environmental sustainability and social responsibility commitments.

[2] For the purposes of the 25PST, we refer to “tuna products” as products where tuna is the key ingredient.

[3] Traceability to vessel and trip dates recognizing the need for aggregated vessel and trip information from small-scale tuna fisheries.

[4] References to human rights utilise the UN Declaration of Human Rights definition.


About the 25PST

To maximise the impact of the 25PST, it has been aligned to the GTA 5-Year Strategy, which includes actions crucial to improving tuna fisheries and was informed by the TTD commitments.


The 25PST ambition

That tuna, globally, meets the highest standards of environmental performance and social responsibility; in particular through demonstrable improvements in supply chain practices and the management of tuna fisheries by 2025.

To achieve our shared ambition, signatories to the 25PST will make improvements under three main commitments:

  1.  Transparency & Traceability
  2. Environmental Sustainability
  3. Social Responsibility

In addition to the minimum commitments, which every signatory commits to, there also are a number of recommended actions through which signatories can achieve the 25PST. These are not exhaustive.
