Warehouses are exposed to rising ambient temperatures and heatwaves; cold chains are exposed throughout storage, transport, and handling stages; and warehouses located in areas with water stress or flood risk can have dependence on water for cooling, sanitation and operations. Temperature-sensitive goods such as food, pharmaceuticals, and chemicals have a high reliance on continuous cooling systems, which are vulnerable to heat stress and overload. Facilities that depend heavily on water for cooling, cleaning and maintenance may also be vulnerable during extreme-weather events.
Small temperature deviations can lead to product spoilage; the knock-on effects are food waste and public health risks that can increase losses across entire supply chains. Water shortages affect facility operations and workforce conditions, and flooding damages infrastructure and causes downtime.
Vulnerabilities
What climate & nature threats impact thermal & cold chain integrity?
The climate and nature pressures that can make thermal & cold chains less reliable.
Thermal and cold chain systems are increasingly exposed to climate and nature-related hazards such as rising temperatures, heatwaves, droughts, storms, and flooding. Extreme heat can place sustained pressure on refrigeration and cooling systems, while storms and floods can damage infrastructure or interrupt power and water supply. Drought conditions may constrain water availability for cooling processes.
These hazards increase the risk of temperature excursions and system failures, undermining the stability of controlled environments required for sensitive goods.
How do location, utility reliance, and transport distances increase exposure?
How exposed thermal & cold chains are to climate and nature risks.
Exposure to thermal and cold chain risks is shaped by geographic location, infrastructure quality, and reliance on external utilities. Facilities operating in regions prone to high temperatures, energy instability or water stress are more exposed. Dependence on centralised power grids, single water sources or ageing cooling systems can further increase vulnerability.
In addition, long transport distances or complex distribution networks can heighten exposure by increasing the duration goods must remain within controlled temperature conditions.
How dependent are businesses on thermal & cold chains?
How much businesses rely on high integrity thermal & cold chains.
Cold chain systems vary in their sensitivity depending on the nature of the goods handled, operational tolerances, and system design. Highly perishable or temperature-sensitive products such as food, pharmaceuticals, and chemicals require strict environmental control and have low tolerance for deviation. Systems with limited backup power, insufficient insulation, or inadequate monitoring are more sensitive to disruption.
High utilisation rates and lack of redundancy can also amplify the impact of even brief temperature fluctuations.
How could disruption spread in thermal & cold chains?
How disruption can create knock-on effects for businesses.
