The summer of 2026 has demonstrated that climate risks are no longer a distant scenario but a present business reality. Extreme heat, drought and low water levels are disrupting supply chains, damaging infrastructure and affecting companies’ costs, operations and financial performance. Climate adaptation therefore needs to be embedded in corporate strategy, governance and decision-making. At the same time, mitigation efforts must continue: companies need to strengthen their resilience to climate impacts while reducing their contribution to climate change. Two discussion papers by the UN Global Compact provide practical guidance on turning climate risk assessments and transition plans into effective management and decision-making tools.
Extreme weather in Europe is no longer a future scenario – it is here
Summer 2021. Heavy rainfall caused streams and rivers to burst their banks, severing logistics routes and causing severe damage to infrastructure. Losses caused by the floods, including those along the river Ahr in western Germany, exceeded 30 billion euros in total, according to government estimates.
Summer 2026. Intense heatwaves with only brief respite marked the third severe drought in just eight years. The Rhine has reached an all-time low, interrupting inland shipping, slowing production and driving up costs for the industries along its banks. A study by Triodos Bank estimates the total EU-wide impact of the 2026 heatwave at a loss of around 1% of GDP.
Climate adaptation is not a disclosure exercise – it is a response to material business risk
The two examples illustrate that extreme weather is no longer confined to distant future scenarios; it is part of today’s operating conditions. It lands squarely on the balance sheet through lost output, damaged assets and rising insurance costs.
The problem is magnified when companies treat climate adaptation as a disclosure exercise rather than a management task: reporting describes exposure; it does not reduce it.
Climate adaptation deserves the same rigour as any other material business risk: risk assessments must be translated into strategy, and incentives must be calibrated to build resilience – not merely promise it. It also means naming who is accountable at the board level and who is responsible for operational implementation.
Adaptation and mitigation need to go hand in hand
We must also be precise about a further point: climate adaptation and mitigation measures are complementary, never substitutes. Cutting emissions remains the single most effective way to limit the physical risks we will all have to adapt to. A credible corporate response advances both at once, reducing both the company’s impact on the climate and the climate’s impact on the company.
The question is no longer whether adaptation matters for business. Companies that embed risk and resilience into strategy, governance and decision-making will be the ones still deciding their own future. Those that leave it to the sustainability report will have that future decided for them. Companies that govern adaptation effectively to protect value can also capture the opportunities of an emerging resilience economy.
The task, therefore, is to coordinate adaptation, make it effective, avoid fragmentation and move beyond well-intentioned promises that have no steering effect.
From climate risk assessment to transition plans
Two UN GCD discussion papers give practitioners a hands-on starting point:
- Understanding Climate Risks and Opportunities Through Scenario Analysis sets out a four-step method aligned with CSRD/ESRS E1, the EU Taxonomy and the TCFD recommendations. It identifies material physical and transitional risks, quantifies their financial impact across revenue, costs, assets and financing, and derives a defensible view of business-model resilience. Crucially, it shows how to move from a first qualitative screen to quantified, decision-ready insight.
- Transition Plans: Strategic Relevance, Steering Potential and Practical Implementation goes beyond reporting to turn plans into a live management instrument. A transition plan helps pinpoint where high emissions and high risk coincide, then links measures, financing and governance, so that adaptation and decarbonisation are steered together rather than in silos.
Join the UN Global Compact workshops at the Climate Adaptation Conference
In the workshop track “Governance and Strategy” (October 14, at 2:30 and 3:20 p.m.), hosted by the UN Global Compact Network Germany, we will address some of the key questions for companies: Where does responsibility for climate adaptation
sit? And what must we consider if we want to translate a location risk analysis into group-wide KPIs? Feel free to get in touch with the UN Global Compact Network Germany and share insights on how to bring adaptation onto your board agenda.
