Top officials from more than 150 countries gather at United Nations HQ in New York City today, to address the leadership challenge of climate change. The event, billed as the largest meeting ever of world leaders on climate change, takes place on the eve of the opening of the UN General Assembly’s annual General Debate. The discussion is intended to build momentum for the UN Climate Change conference in Bali this December where negotiations about a new international climate agreement should start. Sessions will cover adaptation, mitigation, technology, and financing. For our industry’s part, Jacques Aigrain, chief executive officer and member of the executive board committee of Swiss Re, will be speaking.
