83% Now Call Sustainability Critical — But Boards Haven't Built the Machinery

Eighty-three percent of supply chain professionals now rate sustainability as important or very important to long-term business success — the highest figure in the seven-year history of MIT's State of Supply Chain Sustainability research. The 2026 edition, released this month by the MIT Sustainable Supply Chain Lab at the MIT Center for Transportation and Logistics, surveyed 1,810 practitioners across 91 countries.

The headline number comes with a wrinkle. Commitment has grown even as U.S. climate policy has shifted against it: 59% of respondents say they've become more committed to sustainability, against just 13% who report becoming less committed. Corporate resolve, it turns out, isn't waiting for Washington.

Execution is another matter. Nearly 70% of respondents said tariff uncertainty has forced their organizations to delay, scale back, or compromise sustainability strategies. More than eight in 10 said geopolitical conflict is reducing the effectiveness of climate action. In plain terms: the trade environment is doing more damage to decarbonization than any regulator could.

What's failing inside the building?

The report's sharpest finding is a governance gap. Companies with formal cross-functional sustainability teams are far more likely to embed sustainability in everyday decisions — 57% do so frequently or always, versus 13% where responsibility sits within a single function.

Yet only 51% of companies with public sustainability goals have such a team, and only 33% place oversight at board level. As the report puts it: "Many companies have set the direction but have not yet built the internal structures needed to turn those commitments into consistent action."

That's a press release on one side and an org chart on the other, and the gap between them is where most initiatives stall.

Where does the work actually live?

The research mapped where sustainability efforts sit in the supply chain, and logistics is emerging as prime territory. The most common areas of action are:

• Transportation and logistics
• Procurement
• Warehousing
• Product and packaging design

Efforts are far less visible in capital investment, network design, and risk planning — the structural, big-ticket decisions that shape emissions for decades.

"The pattern suggests that sustainability is becoming part of how companies operate their supply chains faster than it is becoming part of how they design them," the report states. Operating a truck fleet more efficiently is one thing. Deciding where the network itself should sit is another.

What's the business case, really?

Here the findings cut against a decade of green marketing. The most widely reported gains from sustainability programs are compliance, operational efficiency, and supply chain visibility. Resilience and risk reduction rank ahead of direct cost savings too.

"The business case for sustainability is driven more by operational gains than by direct cost savings," the report concludes. For carriers and forwarders selling decarbonization services, that framing matters: shippers are buying visibility and compliance, not fuel-bill heroics.

The other themes

Geopolitics and governance make up one of four themes in the report. The research also examines how AI is affecting sustainability goals, and how warehousing and freight transportation operations are progressing toward decarbonization — two threads logistics operators will want to read closely.

For the industry, the practical question is what changes on Monday. The answer from MIT's data: sustainability spend keeps flowing, but it's flowing into daily operations rather than network redesign, and it's increasingly vulnerable to tariff whiplash. Firms that formalize cross-functional oversight — and get the board involved — are the ones converting ambition into results. The rest have targets, and an excuse.
