Climate change is one of the most critical issues to tackle today as it is foreseen to have detrimental social, environmental and economic impacts in the near future. The last climate change events, such as flooding in Germany and Belgium in both Continental and Atlantic regions, heat waves and lack of water in both Mediterranean and Boreal regions, show that the policymakers, experts and stakeholders' actions are not enough, and a 360º citizens engagement is urgently needed. Therefore, we need to learn from the good experience in citizens' engagement in climate change action and build up citizens` supporting infrastructure for climate adaptation measures to help the 150 European regions and local communities to resist. Climate assemblies and Living labs are considered as sustainable and reasonable tools to stimulate deliberative democracy in climate policymaking. Various state governments such as France, UK, Scotland, Ireland, Germany, Denmark and Austria have experience in developing their own mechanisms for engaging and empowering their citizens such as the Climate Assemblies where citizens are invited to deliberate about the adaptation measures for reducing the costs specially for more vulnerable groups. Such public engagement processes typically fall outside of normal practice for public authorities, and thus their outputs must be seen as something which authorities must learn how to interact with and respond to. The goal of our research project is to accelerate the transformation to climate resilience by (i) identifying and describing the underlying mechanisms to empower citizens and enhance their deliberation participation, (ii) mapping and reviewing underlying tools and toolkits that can support citizen engagement and deliberation and (iii) developing innovative actions through citizens engagement mechanisms praxis (e.g. climate assembly) as well create insights, proposals, and suggestions that support the policy making process better.
