NEUROCLIMA is a European project (Jan 2024 – Dec 2026)1, that aims to raise awareness, provide best practices, and ensure sustainable use of climate change adaptation and resilience solutions. NEUROCLIMA leverages both human and artificial intelligence (AI) to support dissemination and communication strategies, it collaborates with other EU-funded initiatives, develops viable business models, standardises outcomes, and invests in frameworks and toolkits addressing citizen and stakeholder needs and climate change challenges. NEUROCLIMA’s impact through the use, commercial and other, may span well over 2030. D5.1: Design toolkit towards behavioural change, citizen engagement and improved policy is a practical guide developed by the NEUROCLIMA project to support climate change adaptation efforts at the community level. It is the direct output of Task 5.1, aiming to create a participatory design toolkit that utilises behavioural science, participatory methods, and real-world examples, consolidating them into practical tools and activities hoping to increase the engagement of citizens, students, and decision-makers into actions and policies aligned with the EU Adaptation Strategy and the Mission on Adaptation to Climate Change.
