Climate Impact Diagrams

Climate Impact Diagrams aim to build a shared understanding among all city stakeholders on the opportunities and risks of climate change for the different city sectors. It is a first step to start the conversation about climate change adaptation and work towards a joint approach for taking climate measures, identifying co-benefits and offering ideas for action. 

Impact diagrams present a simplified, visual summary of current scientific knowledge of climate effects and climate consequences in a city. The diagrams help to gain more insight into opportunities and risks and can kickstart the search for additional knowledge or collaboration partners. 

Benefits of using the tool

  • The impact diagrams are decision support tools appealing for policymakers. They visualise possible outcomes for those making climate investment decisions and enhance dialogue between science and policy.
  • They offer a visual summary of the climate change impacts  by sector (economic, social and natural) in order to contribute to the development of adaptation plans.
  • Impact diagrams can help cities and city staff to gain insight into the opportunities and risks of climate change for their own field of work, and can enable focussed discussion between stakeholders about adaptation options and priorities.


City Hub experiences

Logroño has organised a climate impact diagram workshop, together with CAS and Tecnalia, in order to prepare for the Sustainable Energy and Climate Action Plan (SECAP).
