State protocol, UN standard

Few companies in the world have run so many State events: Rio-92, Rio+20, the G20 Summit and COP-30. Multilingual conference systems, operational security and zero tolerance for failure, because history has no second take. At COP-30, world leaders, from Ursula von der Leyen to Friedrich Merz, followed the negotiations through Hoffmann headsets.
