5 Steps to Build Climate-Resilient Supply Chains
Marsh has published guidance on five critical steps for organizations to enhance supply chain resilience in the face of escalating climate risks. This framework addresses the growing reality that climate-related disruptions—from extreme weather events to resource scarcity—pose material threats to global supply networks. The guidance is timely as companies face increasing pressure from stakeholders, regulators, and insurers to demonstrate climate preparedness. The article underscores a structural shift in supply chain management: climate resilience is no longer an optional sustainability initiative but a core operational requirement. Supply chain professionals must integrate climate risk assessment into sourcing decisions, supplier evaluation, facility planning, and inventory strategy. Organizations that fail to build climate redundancy into their networks risk facing costly disruptions, regulatory penalties, and competitive disadvantage. For practitioners, the implications are significant. This guidance signals that supply chain teams must collaborate with risk management, sustainability, and procurement functions to map climate exposure across their networks, diversify sourcing geographies, invest in predictive analytics, and build adaptive capacity into logistics infrastructure. Companies that embed climate resilience into their supply chain strategy now will be better positioned to navigate future disruptions and capture competitive advantage.
Climate Resilience Has Become a Supply Chain Imperative
Marsh's latest guidance on strengthening supply chain climate resilience marks a critical inflection point: climate adaptation is no longer a corporate sustainability checkbox—it's foundational operational strategy. As climate-related disruptions intensify globally, supply chain professionals face mounting pressure to integrate climate risk assessment into network design, sourcing decisions, and contingency planning. The stakes are concrete: supply networks exposed to climate hazards face production shutdowns, transportation delays, facility damage, and commodity price volatility. Organizations that treat climate resilience as optional risk are already falling behind competitors who have begun embedding climate adaptation into their core operating models.
The business case for climate resilience is compelling. Extreme weather events disrupted supply chains with unprecedented frequency in 2023-2024, from floods affecting semiconductor production in Southeast Asia to droughts constraining agricultural logistics. These disruptions moved beyond headline risk—they translated directly into inventory stockouts, customer service failures, and margin compression. Insurers and financial institutions are now pricing climate risk into coverage and credit decisions, making climate resilience a factor in supply chain financing and capital allocation. Regulators in key markets are beginning to mandate climate risk disclosure for supply chain operations. The convergence of these pressures means that climate resilience is rapidly becoming as critical as cost and speed in supply chain competition.
Translating Climate Resilience Into Operational Action
Marsh's framework points supply chain leaders toward concrete interventions. First, risk visibility is foundational—organizations must map supplier locations, facility locations, and critical logistics corridors against climate hazard data to identify concentration risk. Many supply chains remain blindly exposed to climate hazards simply because risk mapping has never been conducted. Second, geographic diversification reduces concentration risk; sourcing strategies should deliberately spread supplier and facility portfolios across regions with lower correlated climate exposure. Third, infrastructure investment in climate-adaptive facilities and logistics systems—from hardened warehouses to climate-resilient transportation—strengthens operational continuity. Fourth, scenario planning and stress-testing enable supply chain teams to model disruptions and adjust policies (safety stock, capacity, lead time buffers) before crisis strikes. Fifth, collaborative supplier partnerships focused on mutual climate adaptation—sharing best practices, co-investing in resilience measures, and jointly planning for disruptions—turn individual organizations into resilient ecosystems.
The operational implications for supply chain teams are immediate. Procurement functions should integrate climate risk scoring into supplier selection and contract negotiations. Demand planning and inventory management should adjust safety stock policies based on climate risk exposure and lead time volatility. Logistics teams should diversify transportation modes and corridors to reduce dependence on climate-vulnerable chokepoints. Facility planning should evaluate long-term climate exposure before major capital investments. Cross-functional collaboration between supply chain, sustainability, risk management, and finance functions is essential—climate resilience cannot be delegated to sustainability teams; it must become embedded in every supply chain decision.
The Competitive and Strategic Imperative Ahead
Organizations that view climate resilience as a defensive cost are missing the strategic opportunity. First-movers in climate-adaptive supply chain design are building competitive advantage through lower disruption costs, faster recovery, and superior customer service during climate events. They're also attracting investment capital, talent, and customer loyalty. Conversely, supply chains that remain exposed to climate risks are accumulating tail risk that will eventually materialize in operational crises.
The path forward is clear: supply chain leaders should commission climate risk audits of their networks, establish cross-functional climate resilience governance, begin geographic diversification where concentration risk is high, and integrate climate scenarios into annual strategy reviews. Climate resilience is no longer a future concern—it's a present operational necessity.

Frequently Asked Questions
What This Means for Your Supply Chain
What if a major supplier region faces drought-induced production outages?
Model the impact of a 6-month production shutdown at suppliers concentrated in a climate-vulnerable agricultural region. Assess inventory depletion, lead time extensions from alternate suppliers, and cost inflation. Evaluate whether current safety stock and diversification strategy adequately cover the disruption.
Run this scenarioWhat if climate impacts extend lead times by 3-4 weeks?
Simulate the operational impact of climate-driven delays to transportation corridors (port congestion from weather, rail disruptions, inland waterway restrictions). Model how extended lead times affect inventory levels, forecast accuracy, and service levels. Determine what inventory buffer is needed to maintain target service levels.
Run this scenarioWhat if facility climate exposure requires network rebalancing?
Model the cost and service impact of relocating warehouse or distribution capacity away from climate-exposed regions (flood zones, hurricane corridors, extreme heat areas). Calculate facility investment requirements, transportation cost changes, and service level implications across customer segments.
