While the World Humanitarian Summit (WHS) presents an opportunity for the humanitarian sector to agree on how to further improve its performance, there is also a risk that while it triggers a great deal of discussion, the Summit may fall short of delivering substantial, actionable recommendations that lead to more effective humanitarian action. The Core Humanitarian Standard is an opportunity for the WHS to promote an action oriented framework and a common language on issues of accountability to affected communities, effectiveness, principled humanitarian action and disaster preparedness. This paper briefly presents the CHS, its benefits, its relevance to the WHS, highlights the support it has already garnered, and gives practical recommendations to key stakeholders.
