Faced with global concerns about increasing vulnerability of the global system and its sustainability, private companies are asked and encouraged to contribute to the implementation of the 2030 Agenda for Sustainable Development Goals (SDGs) through multi-sectoral partnerships. Implementing the SDGs will require coordinated and collective efforts by all stakeholders to move the world forward towards a shared vision as set out in the SDG goals and targets. Business diplomats representing the interests of enterprises are crucial to ensure a mutually beneficial participation of business in the implementation of the SDGs. Propositions are made in this chapter to outline the requisite competencies needed to implement business diplomacy both at the organisational and managerial levels in the context of SDGs implementation.
