Aim: In this paper, we analyze the potential of various digital tools such as gamification-based applications or digital currencies in enabling the social engagement in climate change mitigation processes by encouraging pro-environmental behaviors. Therefore, as a result of this study, we aim to develop a conceptual framework for a green digital tool, dedicated to cities seeking to shape their resilience by supporting bottom-up initiatives and encouraging residents to join the effort through educational interventions. Methods: The study was divided into four steps using a variety of methodological approaches, including a review of the SLR literature, analysis of the successes and failures of existing solutions, and qualitative workshops with stakeholders. Findings: The conceptual basis of the proposed solution has been developed based on the existing knowledge on pro-environmental nudging and lessons learnt from existing solutions. Value/originality: The developed conceptual framework can contribute to local economies while promoting social solidarity. It has the potential to build communities which can act together for the purpose of urban climate resilience because, from the very beginning, it is co-created together with residents. Practical implementation and beneficiaries: The concept described in this paper can serve cities as a supportive solution, shaping climate change awareness and attitudes toward active engagement.
