Safe from Floods? A Look at Luxembourg’s New Climate Change Adaptation Plan

Introduction

July 14, 15, and 16, 2021, were marked by the costliest natural disaster in Luxembourg’s history: Insurers paid out 133 million euros in financial aid to victims, and 30.4 million^[1] euros paid by the government. This flood was not an isolated incident. According to LIST^[2], the average temperature in Luxembourg has risen by more than 1°C since the 1960s. The resulting effects of climate change—which we regularly witness around the world—will intensify in both frequency and severity, posing very serious risks to infrastructure, public health, and economic activities as a whole.

It is in this context that the Ministry of the Environment, Climate, and Biodiversity is publishing a draft Strategy and Action Plan for Adapting to the Effects of Climate Change in Luxembourg for the period 2025–2035. This document is intended to guide public and private stakeholders in preparing for these risks and protecting themselves from them as much as possible.

In this article, we offer a brief overview of this new plan: its progress, its next steps, and how economic stakeholders—manufacturers, financial institutions, and service providers—can take advantage of it, provided they rely on robust methods.

Real Progress

To begin with, we must commend the very existence of this initiative: given the systemic and multidimensional nature of the risks posed by climate change, developing an adaptation strategy is essential for establishing a shared understanding of the challenges, coordinating key stakeholders, and facilitating the structuring of their adaptation efforts over time.

Let’s take the example of a fictional digital company, “Adapt-IT,” which has data centers in Luxembourg and also relies on servers in the United States. It is exposed to weather-related risks that could affect its own offices and data centers—both locally and internationally— but also to essential services—provided by other entities—on which it depends (e.g., water supply for air conditioning systems, power availability to run servers, road accessibility so employees can get to work, etc.). Furthermore, in order to conduct a risk assessment, “Adapt-IT” will need to cross-reference its internal data (e.g., geolocation and analysis of its data centers’ vulnerability to weather-related hazards) with external data produced by third parties (e.g., projections of weather-related hazard trends) that are specific to each region. Finally, it will need to distinguish between direct levers for action and those that fall under the purview of other stakeholders (e.g., suppliers, service providers, regions, industries). Without a systemic, specific, and shared understanding of risks, assessments remain incomplete, action plans are ineffective, and investments are misdirected.

Luxembourg’s new National Adaptation Plan addresses these challenges with significantly greater ambition. Compared to the previous version (2018–2023), it broadens its scope—covering 16 areas of action, up from 13 previously—and outlines a set of 131 concrete measures. Several new areas have been added, such as soil protection, regional and international cooperation, and education, communication, and awareness-raising, reflecting a more cross-cutting and systemic approach.

The plan is also distinguished by a more operational governance structure, centered on a five-step adaptation cycle (assess, plan, implement, monitor, adjust) and by an explicit commitment to localizing action. Initiatives such as the Climate and Nature Pacts aim to engage municipalities in the local implementation of the plan, while planning tools such as municipal adaptation plans are encouraged.

The plan highlights nature-based solutions as a key pillar of adaptation. Whether it is a matter of managing excess water, mitigating the effects of droughts, or cooling cities, these solutions offer a response that is at once environmentally friendly, resilient, and economically sustainable.

Finally, the Ministry is presenting this draft adaptation strategy to the public for “ refine the proposed measures, incorporate new ideas and measures, and mobilize and engage all stakeholders in the adaptation strategy "^[1].

This plan therefore lays the groundwork for a coherent, integrated, and potentially transformative adaptation strategy—provided, however, that it can be supported by concrete methods for implementation at the organizational and regional levels.

Next Steps

Despite these advances, in order to ensure effective implementation, this plan should be accompanied by an operational timeline and a clear methodological framework.

First, the plan could provide more details regarding the budget and the operational timeline. In particular, the timeline must take into account the fact that some companies have never addressed adaptation issues before and therefore require enhanced support.

Second, the plan could be accompanied by a clear methodological framework to guide organizations in assessing their exposure to climate risks. To ensure the quality of assessments and adaptation plans, it is essential to define the characteristics of a rigorous, structured assessment that is consistent across stakeholders.

Third, to be comprehensive, this plan could incorporate a specific approach for high-impact climate shock scenarios: rare but plausible combinations of extreme hazards that could disrupt vital systems or cause critical disruptions in certain value chains. This type of analysis, which is still in its early stages, would benefit from a concerted effort between public and private stakeholders.

OCARA: A Proven Method for Economic Stakeholders

In this context, and in light of the objectives set forth in the plan, the OCARA method provides a robust analytical framework for addressing the issue of adaptation. It not only helps to inform reporting frameworks such as the CSRD, but above all enables the development of concrete adaptation pathways tailored to each stakeholder, in line with the key principles outlined in the national plan. This method is publicly available on our website.

With more than ten years of experience working alongside businesses across all sectors, we have developed recognized expertise in assessing risks related to climate change and developing adaptation plans, both at the site and corporate levels. Today, we conduct climate risk assessments for our clients, help them structure their adaptation strategies, and provide training and tools to enable them to effectively put adaptation into practice.
