The aim of the Carbon Handbook is to present a framework conducive to sound carbon management. It targets those responsible for developing and managing a carbon strategy for world class events (WCE). The Handbook covers everything from setting goals and targets to providing case studies, which illustrate how the others have succeeded in reducing the carbon emissions of their events. This document has been inspired by the Sochi 2014 Winter Games and based on the ample experiences and case studies gained during the preparation and staging the Sochi 2014, London 2012, Beijing 2008 Olympics, American Cup 2014, World Cup 2014 in Brazil and the others. At the same time it is necessary to emphasize that the Handbook is also relevant not only to sporting but also to other types of events: such as international conferences, exhibitions, festivals, etc.
