Since 2016, Calmy-Rey has been a Member of the board of the Global Leadership Foundation (chaired by FW de Klerk), an organisation that works to support democratic leadership, prevent and resolve conflict through mediation and promote good governance in the form of democratic institutions, open markets, human rights and the rule of law. It does so by making available, discreetly and in confidence, the experience of former leaders to today's national leaders. It is a not-for-profit organisation composed of former heads of government, senior governmental and international organization officials who work closely with heads of government on governance-related issues of concern to them.
