Executive Summary
Exceptionally low water levels across major European rivers are disrupting freight transport, electricity generation and industrial activity as prolonged heat and drought continue across the continent.
The Rhine is particularly important because it links Rotterdam with major industrial centres in Germany and central Europe. Around 285 million tonnes of freight are transported on the river annually, and it carries a substantial share of Germany’s inland waterborne goods.
Low water means vessels cannot sail fully loaded. Cargo therefore has to be divided among additional barges or transferred to road and rail, increasing both cost and delay.
At the same time, low river levels and higher water temperatures are reducing hydroelectric production and constraining some nuclear generation that depends upon river water for cooling.
UK Impact
UK businesses may be exposed through European suppliers even where their own goods never travel by river.
Affected commodities include:
- Chemicals.
- Petroleum products.
- Grain.
- Coal.
- Minerals and ores.
- Industrial raw materials.
- Heavy manufacturing components.
A German manufacturer may still be operating normally while experiencing significantly higher costs or delays in receiving raw materials.
UK businesses importing from continental Europe should therefore consider the resilience of the transport infrastructure behind their supplier—not merely the supplier’s factory.
Global Impact
The disruption demonstrates how environmental conditions can affect several infrastructure systems simultaneously.
Low river levels can cause:
- Reduced barge capacity.
- Higher road and rail demand.
- Increased freight rates.
- Lower hydropower output.
- Constraints on nuclear generation.
- Agricultural losses.
- Higher industrial energy costs.
European utilities have already reported material financial impacts from weak hydrological conditions, while some freight volumes moving between Rotterdam and the Rhine have fallen below normal levels.
Extreme heat is therefore becoming not only a physical climate risk but also a logistics, inflation and credit risk.
Our View
Businesses often know the country in which their supplier is located but not how that supplier receives raw materials.
That information is becoming increasingly important.
Companies should:
- Identify suppliers dependent upon inland waterways.
- Establish alternative road or rail routes before capacity becomes scarce.
- Review contracts governing freight surcharges.
- Increase safety-stock levels for critical commodities where appropriate.
- Confirm whether suppliers maintain alternative transport arrangements.
- Stress-test procurement against prolonged low-water conditions.
- Examine business-interruption cover where disruption occurs without damage to the insured premises.
- Monitor key transport chokepoints rather than national weather forecasts alone.
Climate resilience increasingly means understanding how goods physically move through the supply chain.
