In a second letter to the UN member states on Tuesday, the COP Troika called for an earlier submission of Nationally Determined Contributions (NDCs). If possible, they should be submitted as early as the UN General Assembly on September 10 in New York to send a signal that the 1.5-degree limit is being met. The Troika wants to lead by example. COP29 host Azerbaijan as well as Brazil (host COP30) and the United Arab Emirates (host COP28) promise in the letter to send appropriate signals within their national capabilities.
