When corporate leaders discuss climate strategy, sustainability remains a top priority. The MIT Sustainable Supply Chain Lab’s 2026 report surveyed 1,810 professionals, finding 83% rate sustainability as important or very important for long‑term success—the highest in seven years. Yet commitment does not equal capacity. 59% say recent U.S. policy shifts have made them more committed, while 68% report tariff uncertainty forcing them to delay, scale back, or abandon sustainability plans, and almost one‑third see tariff‑related disruptions raise operational emissions. The report notes strong commitment, expanding measurement, and AI acceleration, but converting commitment into accountability, integrating operations into strategy, and achieving real decarbonisation are harder. Ongoing geopolitical conflict is also eroding climate action effectiveness, with over 80% of respondents saying conflict reduces their organization’s impact. Governance is weak: only 51% have a formal cross‑functional sustainability team and 33% place oversight at the board level. Companies with such teams embed sustainability in decisions 57% of the time, versus 13% when responsibility sits in a single function. Sustainability is most embedded in transportation and logistics (39%), procurement (35%), warehousing (34%) and product design (33%), but thins out in long‑term decisions like capital investment, network design, and risk planning. AI use is widespread—78% of North American firms use AI, 87% see positive impacts, 86% cut material waste, 81% reduce energy use, and 63% estimate missing supplier emissions. However, only 53% of mature AI users report total greenhouse‑gas reductions, while 29% see increases. In advanced automated warehouses, 78% report higher energy use and 76% higher waste, with only 24% employing real‑time AI monitoring. Freight companies are reducing emissions through route optimization and load consolidation, yet 43% of fleets still run mainly on diesel and only 8% have fully transitioned to low‑emission energy. Policy clarity drives regional differences: 84% of European firms say recent policies aid decarbonisation versus 44% in North America. Battery‑electric trucks are deployed by 60% of European companies but only 36% of North American ones. A bright spot appears in Scope 3 collaboration: joint supplier decarbonisation programs rose from 31% to 58%, partnerships to manage shared supplier emissions more than doubled from 23% to 55%, and firms working alone fell from 18% to 6%. The consistent pattern is that corporate commitment is not the main constraint; governance, accountability structures, technology infrastructure, and measurement capabilities are. Organizations that build external resilience and internal accountability will see their commitments survive; those that do not will make little progress.
