ECO gives a summary of international climate change negotiations on a day-to-day basis throughout the two weeks and is geared towards French-speaking, primarily African, negotiators and journalists. The bulletin is available in paper format every morning in the conference centre and can also be consulted online.

Within the scope of the international negotiations concerning the Kyoto protocol in Bali, Résau Action Climat published a daily news bulletin in French, ECO, which was handed out to all participants free of charge. Support from the Foundation for this project has continued for the December conference in 2008 in Poznan and in 2009 in Copenhagen.
