The IOC Sustainability and Legacy Commission under the chairmanship of HSH Prince Albert II of Monaco met for its annual meeting in Lausanne on 17 January. The IAKS was represented there by its President Dr Stefan Kannewischer. After introductory presentations, and particularly that of the first IOC Sustainability Report, small groups were formed to mainly discuss communication in the fields of sustainability and legacy. Having introduced its Agenda 2020, the IOC has redoubled its efforts enormously in these areas and achieved much in the last few years. It is now a question of communicating these achievements better to expert circles and the public. Its efforts in the sustainability sector refer to the IOC as an organisation, the Olympic Games and the Olympic Movement.
