When corporate leaders discuss climate strategy, the message that still dominates is that, despite competing priorities and external pressures, sustainability matters. 

According to the 2026 State of Supply Chain Sustainability report from the MIT Sustainable Supply Chain Lab, which surveyed 1,810 supply chain professionals across 91 countries, 83 percent rate sustainability as important or very important to long-term business success, the highest level in the report's seven-year history.

But commitment, the report reveals, is not the same as capacity. While 59 percent of respondents report becoming more committed to sustainability following recent U.S. policy shifts that deprioritize environmental concerns, the same organizations are being forced to compromise those commitments. Sixty-eight percent report that tariff uncertainty has compelled them to delay, scale back, or abandon sustainability strategies. Nearly one-third have seen tariff-related disruptions actually increase their operational emissions.

"Commitment is strong, measurement is expanding, and AI is accelerating," says Sreedevi Rajagopalan, director of the MIT Sustainable Supply Chain Lab and lead author of the report. "What comes next is harder: converting commitment into accountability, operational integration into strategic decision-making, and incremental decarbonization into genuine transition."

The result is a supply chain sustainability agenda stuck between conviction and constraint. 

Beyond tariffs, more than eight in 10 respondents across North America, Europe, and Asia agree that ongoing geopolitical conflict is reducing the effectiveness of their organization’s climate action. Organizations built decarbonization plans on assumptions of stable trade and relative peace, yet neither assumption is holding.

The external disruption reveals an internal vulnerability.
