The Brazzaville Foundation obtains observer status at the United Nations Framework Convention on Climate Change

The observer status confers to a organisation which benefits from it the following means of action:

- attend the sessions of the Convention ;

- submit statements during the official proceedings (NGO group members are encouraged to work with NGO group focal points to develop statements);

- organise side events and exhibitions (applications must be received through the online side event and exhibition registration system);

- participate in workshops and meetings mandated by the COP or subsidiary bodies (vehicles for advice, expert input and information sharing).

In November 2022, the Brazzaville Foundation celebrated its new status by participating in COP27 in Sharm el-Sheikh, Egypt, allowing it to deepen its investigation launched during the pre-COP in Kinshasa: "Climate Change: Africa's Solutions.".

For the Foundation, it is a question of showing that Africa has projects to respond to the challenges posed by climate change and to meet the global challenges of adaptation and mitigation. It is another way of conceiving growth, progress and development under climate constraints.

The first working relationship between UNCAC and Brazzaville Foundation dates back to 2016, when the Republic of Congo launched the Congo Basin Blue Fund initiative at the First African Summit for Action on Continental Co-Emergence at COP22 in Marrakech, Morocco in 2016, in the presence of Denis Sassou N'Guesso, President of the Republic of Congo, and Jean-Yves Ollivier, President-Founder of Brazzaville Foundation, with the support of H.M. King Mohammed VI of Morocco. The Foundation then initiated the creation of the fund in collaboration with its experts who produced a pre-study, suggesting that the countries of the Congo Basin collaborate at the sub-regional level to preserve this exceptional ecosystem while inventing another development model.

In November 2021, the Foundation was also present at COP26 in Glasgow, Scotland, to accompany the member countries of the Congo Basin Climate Commission (CBCC) and promote the Congo Basin Blue Fund.

For information, UNFCCC entered into force on 21 March 1994. Today, adherence to the Convention is almost universal. The 197 countries that have ratified it are called Parties to the Convention. UNFCCC is a "Rio Convention", one of three adopted at the "Rio Earth Summit" in 1992.
