Climate Change Intensifies Economic Strain on German Large Enterprises, Highlighting Need for Resilient Supply Chains and Insurance Strategies

The increasing effects of climate change are hitting German companies hard, especially large enterprises, according to the recent 2025 KfW Climate Barometer. Over 21% of German companies—around 800,000 businesses—report negative impacts due to climate change, with 74% of large companies earning over €500 million annually facing climate-related challenges. Medium-sized companies are also affected, with 42% experiencing issues, while smaller businesses report lower impact at 19%. The vulnerability of large firms is heightened by their global supply chain connections, exposing them to disruptions from extreme weather events like droughts, storms, and floods, which impair production and logistics.

Energy-intensive sectors are particularly strained, as 31% of these companies report climate-related negative impacts, exacerbated by recent dry summers that limit transport routes and cooling for power plants. Notably, the share of large companies affected rose sharply from 61% in 2024 to 74% in 2025, signaling the intensifying economic risks posed by climate change. This underscores the critical need to integrate climate risks into business models, promoting investments in more resilient supply chains and sustainable operational practices to maintain economic stability.

Alongside these climate challenges, German companies face broader risks in their supply chains, including geopolitical tensions such as the Middle East conflict, which disrupts assets and increases energy prices. Insurance coverage plays a vital role in mitigating financial risks amid these volatile conditions. However, standard business interruption insurance often only covers losses following physical damage, leaving gaps when supply chains are disrupted without property damage. Newly emerging parametric insurance products can cover non-physical losses caused by geopolitical events, although war exclusions remain a significant limitation in many policies.

Companies must carefully navigate complex insurance conditions, including war and terrorism exclusions, and consider innovative solutions like captives and specialized political risk insurance to protect their operations. The rising threats from climate change and geopolitical risks collectively emphasize that climate protection and risk management are now essential economic factors for large enterprises, shaping future competitiveness and stability.

As stated by the KfW Climate Barometer, "Climate protection is not just an ecological concern but a vital economic issue," and companies that adopt early adaptation measures are likely to gain long-term advantages. This dual challenge calls for robust strategic responses addressing both climate-related vulnerabilities and geopolitical risk exposures to secure Germany's large enterprises in an increasingly uncertain global landscape.
