The coronavirus pandemic has exposed the vulnerability of global supply chains, as well as the risks and obstacles that supply chain executives and managers contend with every day. But climate change, even more than COVID-19, is a particularly challenging disruptor to supply chains — and its impact is growing more pronounced.
A company’s supply chain consists of the suppliers providing materials, goods and services necessary for it to operate smoothly. It includes the company’s immediate supply base — meaning the suppliers it does direct business with — as well as the suppliers of those direct suppliers. The supply chain of a canned beverage company, for example, includes the metal can manufacturer, as well as the metal mining company that supplies the can-maker.
Our broader research on supply chains in the climate change era makes clear: Every business’s suppliers must deliver consistently to meet customer demands while keeping costs from spiraling out of control, but climate change is making those two requirements increasingly challenging.
Extreme weather events are becoming more severe and frequent worldwide. Rising oceans are creating new difficulties, since most of the world’s critical shipping hubs are built in low-lying areas, exposing them to the devastating impacts of rising sea levels1.
Automaker Subaru, for example, shut down two car factories for part of 2019 due to Typhoon Hagibis and the flooding of its part suppliers’ factories. Clothing brands that use suppliers in East Asia routinely experience delays in supply during monsoon season.
Climate risks can create a lack of available supply, lower the quality of supply, increase the cost of supply or delay the delivery of supply, putting the company’s own operations at risk. A business that fails to adapt its supply chain risk management strategy to account for climate change, in fact, may be putting a significant portion of its corporate value at risk2.
What’s different about supply chain risk due to climate change compared to other types of disruptions?
First, climate change increases the frequency and scope of acute supply chain disruptions. This requires companies to invest more time and money in their supply chain risk management programs.
Second, it can create chronic changes to supply chains, forcing companies to urgently adapt.
Third, it can create new types of risks that haven’t typically been addressed by supply chain risk management programs. These include disruptions in more places, forced structural changes and greater investor attention and scrutiny on supply chain related greenhouse gas (GHG) emissions.
All of this requires companies to formally and immediately incorporate climate change risks as part of their supply chain risk management strategy.
