Just In Clime, aims at advancing and enhancing the understanding and operationalization of climate justice in the context of mitigation and adaptation policies and strategies to ensure a just transition to a climate-neutral and climate-resilient society, reducing inequalities and leaving no one behind. In Just In Clime, partners from Europe, North America, the Middle East & North Africa and Sub-Saharan Africa will join forces in an international collaborative research endeavor to include the visions and perspectives of the “Global North” and the “Global South”, developing consensus with the UNFCCC towards just climate transition processes. Through co-creation and participatory processes, pilots in 9 countries (Spain, Italy, Cyprus, Canada, Senegal, Tanzania, Zimbabwe, Lebanon and Tunisia) will approach justice in climate change in different sectors: agriculture, blue economy, energy and urban development. They will co-develop a novel policy-oriented framework to increase the understanding of justice in climate change transitions, its multiple dimensions and interactions. Jointly, they will also identify, document and analyze current experiences and good practices of inclusion of justice criteria in mitigation/adaptation plans and will operationalize the concept of justice and just transitions through justice-related indicators. Roadmaps for just climate transitions will be co-produced and actionable policy recommendations on how to design, implement and evaluate mitigation and adaptation policies/strategies to achieve climate transitions that take into consideration the needs and concerns of different groups of society will be produced and widely disseminated. Researchers, NGOs, specialized SMEs, and international Networks active in the fields of sustainable development, resilience and democracy bring in Just In Clime a rich tapestry of skills and capabilities, making the project truly interdisciplinary and innovative.
