Klimalotse - Supporting management of climate change risks and chances (decision support system)

Background and Goals

Objective: Creation of an information and decision support system for management of climate effects, particularly for communities and businesses in Germany.

The background to the project is the increasing urgency of the issues of climate change, climate effects and adaptation. The project addresses the increasing need for advice from various adaptation players and the growing interest in tools and methods for appropriate climate effect management.

The project will focus on development the Climate Pilot, an information and decision support system that will be generally accessible as online guidelines through the ⁠KomPass⁠ website from the summer of 2010. Using structured questions in five modules, users will be made aware of the issue of adaptation and introduced to systematic analysis of the risks and opportunities of climate change for the relevant organisation.

The methods proposed by the Climate Pilot, e.g. risk and multi-criteria analysis, along with a range of example adaptation measures and supplementary materials support users in identifying their own adaptation measures and in implementing and monitoring them. To provide adequate coverage of users' varying information needs, the tool will offer a fast-track option and a more intensive process. Special areas of content are planned for decision makers in communities and in KMUs.

Steps in the process of adaptation to climate change

Step 1: Understand and describe climate change

Approach and results 

Information from global and various regional climate models will be used.

Parameter (climate signals)
  • Heat waves
  • Altered rainfall patterns
  • Higher average temperatures
  • Extreme precipitation (incl. hail, snow)
  • Storm
Further Parameters 

Warmer and wetter winters, hotter and dryer summers, increasing probability and intensity of extreme weather events, such as heat waves in summer and severe precipitation, particularly in winter and spring, and an increase in storm events

Further times 

Up to 2100.

Step 2a: Identify and assess risks - climate effects and impact

Approach and results 

All direct (physical) and indirect effects of climate change, e.g. increase reputation risk for companies in high-emission sectors.

Step 2b: Identify and assess risks - Vulnerability, risks and chances

Approach and results 

Example list of vulnerable areas like industrial and commercial companies that use cooling water from watercourses. Climate change means that the cooling water has higher temperatures in summer. This can reduce the efficiency of cooling processes, and also places an additional burden on the watercourses.

Urgency and priorization of adaptation needs 

Depending on the relevant company

Step 3: Develop and compare measures

Measures and/or strategies 

Example list of adaptation measures: Change in cooling processes in production methods from water and air cooling.

Time horizon
  • 2071–2100 (far future)

Step 4: Plan and implement measures

Costs of the measures 

Depending on company size and selected technology.

In making decisions on larger scale projects with long implementation periods, a quantitative assessment of alternative courses of action is necessary in addition to the qualitative analysis. A quantitative analysis allows for a more accurate evaluation and includes a provision for direct and indirect costs, as well as direct and indirect benefits of adaptation measures (e.g. on the basis of cost-benefit analyses).
