As the world grapples with the escalating impacts of climate change, the resilience and responsibility of supply chains are being tested like never before. Global supply chains are facing an unprecedented wave of disruption, with climate change acting as a primary driver and “threat multiplier” (Center for Climate and Energy Solutions, 2025). In 2025, the global economy suffered an estimated $50 billion in losses due to extreme weather events, underscoring the immediate financial toll of climate inaction (Eastlake, 2026). Events such as floods, droughts, and tropical cyclones are not only becoming more frequent but are also increasing in severity, creating a compound risk that profoundly destabilizes the movement of goods and services.

Climate as a Threat Multiplier

The impacts are far-reaching and interconnected. For instance, droughts are crippling crucial waterways like the Mississippi, Rhine, and Panama Canal, which are essential arteries for global commodity trade. This reduces shipping capacity, causes costly delays, and forces a shift to more expensive and emissions-intensive transport modes. Similarly, extreme rainfall and flooding lead to port closures and infrastructure collapse, causing billions in losses and disrupting manufacturing on a global scale. The apparel industry is acutely vulnerable, with research showing that heat stress and flooding in key production centers are having significant impacts on worker health and factory output (Marsh, 2026). Countries such as the Philippines, Indonesia, India, and Mexico, identified as high-risk sourcing destinations, face severe threats from weather anomalies that can halt entire sectors, from food and beverage exports to textiles and services (Center for Climate and Energy Solutions, 2025).

Decent Work and the Just Transition

The ILO has highlighted the importance of ensuring that the expansion of renewable energy and the demand for critical minerals, for instance, do not exacerbate existing labor deficits but instead create formal, safe, and better-paying jobs (ILO, 2025). The concept of a “just transition” is central, emphasizing that the social and economic costs of the green shift must be equitably distributed, with workers and communities protected. Concurrently, the immediate climate impacts on the workforce, such as extreme heat, pose a direct threat to workers’ physical and mental health, making workforce protection and contingency planning a critical business affair.

The Strategic Imperative for Supply Chain Resilience

The evidence is compelling: companies that actively engage their suppliers on sustainability and climate resilience are significantly better positioned to reduce risk, enhance operational performance, and secure long-term competitive advantage. This approach represents a fundamental shift from passive monitoring to active partnership, recognizing that supply chains are only as resilient as their most vulnerable links (BCG, 2025).

According to CDP, suppliers who received training and support from corporate customers were 1.7 times more likely to complete climate-related risk assessments compared to those who did not, and they are 2.6 times more likely to set science-based emissions reduction targets. This translates directly into reduced risk exposure for the purchasing company. The financial case is equally compelling. Research by Boston Consulting Group and EcoVadis indicates that companies engaging suppliers on decarbonisation are nine times more likely to achieve their Scope 3 emissions reduction targets. This is critical because upstream emissions from suppliers are, on average, 21 times greater than a company’s direct operational emissions. Without engagement, these emissions could trigger liabilities exceeding $500 billion annually by 2030 under projected carbon pricing scenarios.

Mechanisms for Effective Engagement

Successful supplier engagement requires a structured, multi-faceted approach that builds capacity while creating accountability.

Training and capacity building support suppliers in developing the skills needed to measure, report, and reduce emissions. This aligns with leadership goals. 52% of CEOs plan to expand climate-related environmental commitments, while 53% say they will increase their focus on social impact. 96% of CEOs urge their successors to center sustainability in their company vision and culture (UNGC and Accenture, 2025). An informed supply chain significantly reduces risk.

Incentives and accountability mechanisms are essential for driving action. Companies are increasingly integrating sustainability requirements into procurement documents, contracts, and supplier codes of conduct. E.g., Bosch uses internal supplier scores based on CDP data in its purchasing process, offering incentives for strong performance and defining clear expectations for improvement.

Collaborative investment in shared resilience allows companies to address systemic risks that no single organisation can solve alone. Landscape initiatives, where companies work with local partners in key sourcing regions, represent an emerging best practice. Nearly 350 companies have disclosed engagement in over 570 such initiatives, with median investments of $300,000 per company (Ceres, 2026). These programmes address interconnected environmental, economic, and social risks that extend beyond individual supply chains.

Multi-stakeholder coordination is critical for system-wide resilience. The ARISE Global Network emphasises that multi-actor, system-wide approaches are essential for safeguarding production, logistics, and trade in an era of escalating climate impacts (Dibella & Burch, 2026). Companies are moving from reactive, piecemeal responses to proactive, jointly governed resilience models that include cross-company liaison teams and shared learning loops.

A Strategic Asset, not a Cost.

The evidence demonstrates that supplier engagement is not merely an expenditure or compliance burden. It is a strategic asset that strengthens supply chains, reduces risk exposure, and delivers measurable returns on investment. Companies taking a consistent approach to engagement are building resilience that protects revenue, enables faster decision-making, and creates competitive advantage in an increasingly volatile global environment.

The findings from Bosch, EcoVadis, and leading research institutions are consistent: active supplier engagement is the most effective lever for building climate-resilient supply chains. Companies that invest in partnerships with their suppliers, provide the necessary tools and support, and create accountability through transparent measurement are substantially better positioned to navigate the disruptions that will define the coming decade.
