<p>Climate change is placing increasing pressure on health and long-term care systems. More frequent extreme weather events, emerging infectious diseases, and chronic environmental stressors are straining care infrastructures. Socially disadvantaged and multiply burdened groups, especially informal caregivers, are particularly affected. A socio-ecological transformation is urgently needed, with targeted support for informal caregivers. Plant-based diets, active mobility, and health-promoting, climate-friendly environments offer potential synergies for both public health and climate change mitigation. Digital solutions can enhance these co-benefits if they integrate the social environment of caregivers and semi public care spaces. This is the guiding principle of the caring communities’ approach, which focuses on building local networks and cultures of care. Building on this, the project 3WINpA is developing a socio-technical solution that promotes a healthy, socially connected, and climate-friendly lifestyle for caregivers. Key success factors include the use of simple, familiar technologies that support time sovereignty in everyday caregiving, complemented by digital training offers tailored to the target group.</p>
