Why Fast Retailing Bet Its Climate Strategy on Supply Chain Relationships — and Why Your Company Should, Too

At a gathering in New York City, Fast Retailing executives sat down with industry leaders to explain something remarkable: Fast Retailing achieved its five-year emissions reduction target in exactly five years, then immediately raised its ambition by 50%.

The room included Kazumi Yanai, Group Senior Executive officer at Fast Retailing; Tomoya Utsuno, CEO of Fast Retailing’s Innovation Factory; Seneiya Navajas, Sustainability Director at UNIQLO U.S.A.; Jean-Emmanuel Shein, UNIQLO U.S.A. Director of Global Corporate Social Responsibility; Raymond Randall, Senior Manager of Textile Recycling at Waste Management; Michael Sadowski, Executive Director and Board Chair at The Circulate Initiative; Kaley Roshitsh, Editorial Director at Cascale; and Paula Bernstein, Associate Director of Sustainability Science at Worldly, who contributed crucial perspectives on how supply chain data becomes business strategy. Their collective message was direct: The brands that move the needle on climate and responsible operations aren’t the ones with the shiniest targets. They’re the ones that can prove they’ll hit them.

And they’re doing it differently than anyone expected.

How supply chain data became the secret to beating climate targets

Imagine trying to navigate a city without a map. You might know where you’re going, but every detour costs time and money. That’s what managing a supply chain without data looks like for most brands.

Fast Retailing didn’t optimize emissions by luck or wishful thinking. They did it because they knew their supply chain. And because they knew it, they could see where change was possible and where it wasn’t.

This matters beyond the climate scorecard. When a company understands its supply chain deeply—from raw materials sourcing to final production—it gains visibility into costs, risks, quality, and resilience. These are the things that directly hit the P&L.

Like most brands, a majority of Fast Retailing’s impacts comes from suppliers

At the NYC gathering, when the Fast Retailing team explained the breakdown of its Scope 1, 2, and 3 outputs, it reframed everything: most of a brand’s climate impact doesn’t live in its own operations. It lives upstream, with suppliers and manufacturers.

This discovery did something radical. It meant the brand could stop optimizing the wrong things. Its own operations were already 90% cleaner than baseline. Instead it could focus energy where it would actually move the needle.

But here’s the catch: you can’t drive change in a supply chain you don’t understand. You can’t partner with suppliers on emissions reduction if you don’t know their capabilities, constraints, and roadmaps. You can’t ask them to invest in expensive upgrades if you’re shopping around for the lowest-cost alternative next quarter.

How decades-long supplier relationships became a competitive advantage

Many of Fast Retailing’s manufacturing partners have worked with them for decades. That’s not a sustainability talking point, it’s a structural advantage.

Think of long-term supplier relationships like compound interest for your business. A supplier that knows you’ll be buying from them five years from now will invest differently than one bidding on contract. They’ll fund energy efficiency upgrades. They’ll upgrade their technology. They’ll train their teams. They’ll make decisions with the future in mind, not just the next quarter.

“Thinking long-term instead of jumping between partners has made a huge impact in switching from coal to natural gas, for example, because they know what’s coming,” said Yanai. “They have visibility into our operations. We have a shared vision and work to achieve our goals together. Our teams are on site discussing issues not once a year but every day.”

This is how supply chain data becomes business strategy. When you have visibility into supplier capabilities and constraints, you can plan investments together. When your suppliers understand your long-term commitments, they’ll advocate for solutions that work at scale, not temporary band-aids.

That verification and deep understanding of your supply chain is what separates companies that are actually transforming from companies that are performing. It’s the difference between hitting climate targets and pretending you will.

When supply chain data stops being a compliance tool and starts being a business lever

What Fast Retailing demonstrated in that NYC gathering is what Worldly customers live every day: supply chain intelligence isn’t a cost center. It’s a revenue driver.

“If you can’t verify what you claim, it’s just marketing,” said Bernstein. That distinction matters. Data on where materials come from, how they’re made, and what they cost—in actual dollars and environmental impact—lets brands:

• Reduce risk by identifying vulnerable suppliers before they face a crisis
• Control costs by understanding true production expenses and efficiency opportunities
• Scale faster by replicating working supplier relationships across geographies
• Respond to regulation with evidence instead of estimates
• Tell an honest story based on real data

Brand authenticity comes from following through on commitments. Supply chain visibility is what makes that possible.
