Potential Impacts of Wind-Related Perils on Air Freight: Assessing Vulnerability and Mitigating Risks for the Global Supply Chain

Airports play a pivotal role in the global supply chain, particularly for high-value, time-sensitive, and perishable goods. Air cargo is responsible for transporting goods worth trillions of dollars annually, making up a significant portion of global trade by value. With the increasing frequency and intensity of wind-related perils, including tropical cyclones, tornadoes, and wind gusts, understanding the vulnerability of major airports and potential disruptions to air freight is paramount. Our investigation focuses on the exposure of over 70 key global airports to these wind-related impacts from 2020 to 2050 under both a high and low emissions scenario and analyzes the possible downstream effects on the global supply chain. Our findings, derived from models developed by PwC, reveal significant geographical disparities in risk exposure. Airports in the United States, Central America, and many locations in Asia are currently subjected to and projected to face high risk from tropical cyclones. Airports in North America, Northern Europe, and some locations in Asia will likely see an increase in wind gust risk. Additionally, tornadoes are projected to impact more key airports in the United States by 2050. Wind-related perils can lead to severe operational disruptions, including flight delays and cancellations, damage to aircraft and ground equipment, and increased logistical complexity due to rerouting of flights. These disruptions can affect the timely delivery of goods and pose safety risks to passengers and airport staff. To address vulnerabilities that can affect airports and air freight, our study proposes several strategic recommendations. Reinforcing airport structures to withstand high wind speeds and implementing wind-resistant designs can mitigate the risk of damage and operational disruptions. Integrating real-time weather forecasting and early warning systems into airport operations can enable proactive measures to safeguard assets and confirm passenger and cargo safety. Strengthening coordination between meteorological agencies, airport authorities, and logistics providers can enable timely dissemination of critical information and coordinated responses to wind-related events. To help strengthen the global supply chain's resilience against wind-related disruptions, developing contingency plans that include alternative routing and utilizing secondary airports is essential. Companies can employ diversified logistical strategies to reroute shipments through unaffected airports, helping to reduce delays. Public-private business relationships can drive investments in resilience infrastructure and technology, which can lead to more holistic and sustainable solutions. By implementing these targeted strategies, stakeholders can safeguard the global supply chain, support sustainable economic growth, and enable resilience in the face of escalating wind-related risks. Our investigation provides a compelling call to action for policymakers, industry leaders, and the international community to prioritize resilience and sustainability.
