From 2012 to 2013, Köhler served on the United Nations' High-level Panel on the Post-2015 Development Agenda, which was co-chaired by President Susilo Bambang Yudhoyono of Indonesia, President Ellen Johnson Sirleaf of Liberia, and Prime Minister David Cameron of the United Kingdom. The advisory board was established by UN Secretary-General Ban Ki-moon to shape the global development agenda beyond 2015, the target date for the Millennium Development Goals. The Panel produced a final report with recommendations and thereby contributed in the making of the 2030 Agenda for Sustainable Development, which was adopted by all UN member states in September 2015.
