The global seafood market is facing a reckoning. For decades, the sheer scale of tuna consumption has put immense pressure on our oceans, leading to concerns about overfishing and unethical labor practices. As one of the world’s largest seafood producers, Thai Union has spent the last decade trying to change that narrative.
With the release of its 2025 Sustainability Report, the company is marking a 10-year milestone in its SeaChange journey. It’s a significant moment for anyone who buys a can of tuna, as well as for investors and ocean advocates looking for real accountability. But is this genuine progress or just corporate positioning?
The seafood industry is notoriously complex, and tracking a single fish from a massive ocean to a supermarket shelf is no small feat. This article looks at the actual results of Thai Union’s efforts to see how they’re influencing the way tuna reaches your table.
What Thai Union has actually changed in tuna sourcing over the past 10 years
Since the initial launch of the SeaChange strategy back in 2016, the company has shifted away from simply making promises. The goal wasn’t just to talk about the environment but to overhaul the mechanics of how fish are caught and tracked. This ten-year window has allowed the company to move beyond short-term fixes and address systemic issues in the supply chain.
One of the biggest shifts has been the focus on oversight and risk management. In the past, the journey of a tuna was often a mystery once the boat left the dock. Today, there’s a much heavier emphasis on monitoring environmental and social risks before the fish even arrives at a processing plant.
This evolution has fundamentally changed the relationship between the company and its suppliers. By setting stricter requirements, Thai Union has forced a level of transparency that didn’t exist a decade ago. It means that whether you’re buying a brand like Chicken of the Sea or a private label product, the sourcing standards behind it have likely seen a drastic upgrade.
From broad promises to measurable sourcing standards
The company’s approach has matured from general “green” goals into a rigid system of traceability. In the seafood world, traceability is the ability to track a product’s history from the exact vessel that caught it to the final consumer. It’s the most effective weapon against illegal, unreported, and unregulated fishing.
Knowing where a fish comes from makes it much harder for bad actors to hide within a global supply chain. To achieve this, Thai Union has implemented tracking systems that record data at every hand-off point. This isn’t just about saving the ocean; it’s about verifying that no human rights abuses occurred on those boats.
When a company can prove the origin of its catch, it creates a “digital paper trail” that ensures compliance with international laws. This shift into data-driven sourcing is a major reason why their leadership claims carry weight in the industry today.
Why responsible tuna sourcing matters for buyers and the ocean
For the average person in a grocery aisle, these corporate shifts might seem distant, but they directly affect what you’re eating. Stronger sourcing rules mean you can have more confidence that your purchase isn’t contributing to the destruction of marine ecosystems.
Responsible sourcing helps maintain fish populations so that the ocean can continue to provide food for future generations. It also addresses the human element of the industry. By demanding better labor standards, these policies help protect vulnerable workers from exploitation in the middle of the sea.
Ultimately, your shopping choices are a vote for how the world’s resources are managed. When a major player like Thai Union adopts these standards, it makes it easier for consumers to access more ethical options without having to do hours of research themselves.
## Inside the SeaChange strategy and the 2025 Sustainability Report
The recent 2025 report serves as a report card for a decade of work while also signaling a pivot toward even more ambitious goals. This milestone isn’t just an anniversary; it’s the bridge to the company’s next phase, known as SeaChange 2030. According to the Thai Union 2025 Sustainability Report, the strategy has expanded to cover every aspect of the business.
This new plan includes 11 specific commitments that reach far beyond just fishing. It covers everything from climate change to how the company treats its employees in factories around the world. By laying out these goals in a public document, the company is giving the public a way to measure their performance year over year.
It’s important to view these reports as a company-generated snapshot. While they show real progress, they also reflect the metrics the company chooses to highlight. However, for an industry that once operated largely in the dark, this level of public disclosure is a significant step forward.
What SeaChange 2030 adds to the original plan
The updated strategy focuses on five core areas: Human and Labor Rights, Health and Wellness, Climate Action, Circularity, and Biodiversity. This broader focus shows a realization that you can’t protect the ocean without also looking at the world’s climate and the people who work in the industry.
Biodiversity, for instance, focuses on protecting the variety of life in the ocean, ensuring that fishing doesn’t accidentally wipe out other species. Circularity looks at waste, aiming to keep materials out of landfills and back in the production cycle. These additions suggest that the company is trying to manage its path toward sustainability more broadly than before.
This expansion is part of a larger trend where corporations are being forced to account for their path toward carbon neutrality by 2050 and beyond. It’s no longer enough just to catch fish legally; companies now have to show they aren’t destroying the planet’s climate in the process.
The most important numbers and milestones from the 2025 report
The numbers in the 2025 report paint a picture of a company hitting its stride. One of the standout claims is that 100% of their wild-caught tuna now comes from fisheries that are either certified as sustainable or are in a formal program to reach that status. This is a massive change from where the industry stood ten years ago.
Climate targets are also a major part of the update. The company reports a significant reduction in emissions from its own processing plants, using solar power and other energy-saving technologies to lighten its footprint. These milestones aren’t just about the ocean; they’re about the entire manufacturing process.
The report also highlights the move toward 100% recyclable packaging for its tuna products. By making the cans and pouches easier to recycle, the company is addressing the “end of life” for its products, not just how the ingredients were sourced. These facts are easier for consumers to understand than complex fishing regulations.
What the report says about traceability, labor rights, and ocean protection
Thai Union has put a lot of focus on worker safety and fair hiring. They’ve moved to a “employer pays” model, meaning workers don’t have to go into debt just to get a job. This is a crucial step in preventing human trafficking and labor abuse in the global seafood supply chain.
On the environmental side, the report discusses the reduction of “bycatch.” This refers to fish or sea life, like turtles and sharks, that are caught by accident. By using better gear and monitoring, boats can ensure they’re only bringing in the tuna they intended to catch, which is vital for international cooperation for environmental protection.
Reducing bycatch is one of the most effective ways to protect ocean health. When combined with full traceability, it creates a system where every can of tuna has a story that can be verified. This transparency is what the company hopes will differentiate it from competitors who aren’t yet opening their books to this degree.
What this means for the wider tuna industry, and what still needs work
When a company as large as Thai Union makes a move, the rest of the market has to pay attention. Because they buy such huge amounts of fish, they can set the terms for thousands of suppliers worldwide. If Thai Union demands better labor rights or better data, the suppliers have to provide it if they want to keep the contract.
This creates a “race to the top” where competitors often feel pressured to match these standards to remain attractive to investors and conscious shoppers. It’s a clear example of how corporate scale can be used to shift industry norms on a global level. However, this influence comes with its own set of challenges and limitations.
The global nature of the industry means that even the best systems aren’t perfect. There will always be gaps in a chain that spans multiple continents and thousands of individual vessels. While the company’s Global Sustainability Strategy provides a solid framework, the real test is how these rules are enforced in the middle of the ocean.
How a large seafood company can raise the bar for competitors
Size gives Thai Union the ability to experiment with new technologies that smaller companies might not be able to afford. For example, using satellite monitoring or electronic logs on boats can be expensive. Once a leader proves these tools work, they often become cheaper and more common across the whole industry.
By participating in international task forces and setting high bars for their 2030 goals, they are essentially writing the rulebook for what “responsible” looks like in the 21st century. This forces other massive brands to justify their own sourcing practices or risk being left behind by consumers who care about ethics.
This ripple effect is perhaps the most important part of the SeaChange journey. It’s not just about one company getting better; it’s about making it harder for the entire industry to ignore environmental and social costs. It sets a new baseline for what is acceptable in global trade.
The gaps and risks that still deserve attention
Despite the progress, significant challenges remain. Climate change is warming our oceans and shifting where fish live, making it harder to predict the future of tuna populations. Even with 100% traceability, there’s always a risk of seafood fraud or gaps in monitoring on smaller, more remote boats.
Labor rights also require constant vigilance. Identifying exploitation in the middle of the sea is incredibly difficult, and while the “employer pays” model is a great start, ensuring every worker is treated fairly across a global network is an ongoing battle. The threat of toxic runoff and pollution in coastal areas also impacts the very ecosystems these fish rely on.
In the next five years, the focus will likely shift to climate emissions and full supply chain transparency. Investors will be looking for more than just 10-year milestones; they’ll want to see how these strategies hold up as environmental pressures increase. There is still plenty of work to do to ensure the ocean remains healthy for the long haul.
Final Takeaways on Thai Union’s Progress
After ten years of the SeaChange program, it’s clear that Thai Union has done more than just update its marketing. The shift toward responsible tuna sourcing is backed by measurable changes in how fish are tracked and how workers are treated. The 2025 Sustainability Report proves that a company this size can pivot its entire business model toward a more ethical path without losing its market position.
However, the job isn’t finished. While the verified gains in traceability and labor rights are impressive, the industry still faces massive pressure from a changing climate and the inherent difficulty of monitoring the high seas. The move to the 2030 strategy shows the company knows it can’t afford to slow down.
For consumers and investors, the takeaway is simple: transparency is the new standard. The progress made over the last decade shows that corporate accountability is possible, but it requires constant public oversight. As we look toward the future, the success of these programs will depend on whether this commitment to the ocean remains a core part of how the world eats.
