DISTENDER Decision Support System Tool: Turning Climate Data into Actionable Strategies

The Decision Support System (DSS) is one of the key outcomes of the DISTENDER project, created to support policymakers, planners, and technical experts in tackling climate change with clarity and confidence.

The DSS is based on models developed from five DISTENDER Case Studies, but it remains fully adaptable. Regions with different capacities, data availability, and challenges can still benefit from its core functionality.

Built within DISTENDER’s research, methodology and case studies, the DSS combines scientific rigor with practical usability, offering two main functionalities:

  1. Query Indicators for the Five DISTENDER Case Studies
    Explore climate-related indicators (maps and tables) derived from models applied to five diverse European regions. These indicators provide insights into climate impacts and risks across sectors such as air quality, human health, urban heat, agroforestry, energy, and water resources. Users can view spatial data over time, under different socioeconomic pathways and climate scenarios.
  2. Ranking Adaptation and Mitigation Strategies for Your Own Case
    Use the DSS’s Multi-Criteria Decision Analysis (MCDA) tool to generate a ranked list of strategies tailored to your preferences. The system applies a decision matrix and weighting mechanism to compare strategies against climate risk indicators. You can build projects using DISTENDER’s pre-loaded strategies and indicators or add your own to reflect local conditions.

Through these functions, the DSS helps users:

  • Prioritise strategies under uncertainty,
  • Understand trade-offs between alternatives,
  • Communicate results effectively to stakeholders,
  • Structure complex information into policy-relevant insights.

The DSS reflects DISTENDER’s mission to deliver transferable, science-based solutions for climate adaptation and mitigation, supporting the European Green Deal, Paris Agreement, and Sustainable Development Goals.

By combining socioeconomic scenarios, climate projections, sectoral impacts, and cost–benefit assessments into a single user-friendly interface, it enables robust, science-based decision-making.

As cities move toward climate neutrality by 2050, the DSS will remain a legacy tool for authorities, helping them make decisions that are sustainable, scalable, and resilient.
