We will create the first european Tenants 4 Climate Organizing School which delivers innovative education for 20 organisers and tenants leaders in order to mobilise 800 tenants in 4 different countries to take individual and collective action towards housing decarbonisation. Other productions such as energy leaky home maps, legal and political framework resources as well as new engaging tools (vidéo, message design) will support organisers to maximise their mobilising impact.
