In this chapter we explain how an advocacy and policy perspective based on solid evidence is central to the support and empowerment of informal carers globally. We begin by providing the context for understanding informal carers and an advocacy and policy perspective. We explain the central role of the carers movements in advocating with and for informal carers to work for changes and improvements in practices, policies, legislation and research. The development of carers’ associations at regional, national, European and international levels are outlined, highlighting their lobbying role for carer-friendly policies that both support and empower carers. Further, we highlight the importance of carer-friendly policies being widespread and cross-cutting across different government departments so that they not only focus on health and social care, but on all spheres of life affecting carers. The role of a cross-government plan as part of a proactive and comprehensive carers strategy that covers all dimensions of a carer’s experience is described and an example of a European Carers Strategy is provided. We subsequently highlight the key policy hooks that the carers’ movement can use to help ensure that care is on the policy agenda, starting at an international level before focusing on relevant policy hooks at European level.
