Meet Macaozinho, an AI chatbot specialising in global climate change
Available in more than 50 languages, ‘Macaozinho’ is a reliable source, as it has been trained using official documents from UN climate agencies

Macaozinho, an artificial intelligence (AI) tool specialising in information on global climate change, is now live. The chatbot is a reliable guide for navigating discussions at COP30 and future climate conferences.
Macaozinho differs from other AIs in that it is a reliable source, as it is trained using official documents from UN bodies such as the UNFCCC (United Nations Framework Convention on Climate Change) and the IPCC (Intergovernmental Panel on Climate Change).
With a name inspired by Brazilian macaws and available in more than 50 languages, Macaozinho is an ally in the midst of an environment of fake climate news and can be used by audiences with varying degrees of familiarity with topics related to international climate negotiations, such as:
The general public, who, for example, hear about the importance of NDCs at COP30 but do not know what the acronym stands for. Macaozinho explains that Nationally Determined Contributions (NDCs) are targets set by countries to reduce emissions and adds that 2025 is the year for reviewing these contributions and that, therefore, they will be the focus of the COP in Belém.
Delegations can use Macaozinho to help their negotiators track discussed texts, retrieve precedents, and cross-reference data to support arguments. They can also translate, summarise, and analyse complex documents with technical accuracy, such as the text approved in Rio 92 or the Kyoto Protocol targets.
Groups involved in climate action, such as organisations, governments, companies, and academia. Macaozinho supports the technical training of those involved, for example, by explaining complex jargon, such as carbon markets, in an accessible way.

Macaozinho is available at www.macaozinho.com or via www.routetobelem.com/macaozinho and will soon be available on WhatsApp. It has already been used, on a limited basis, at events such as the Climate Conference in Bonn (Germany) in June, when it was tested by international negotiators, with excellent results:
🇹🇿 “I was impressed with this bot,” said Richard Muyungi from Tanzania, chair of the African Group of Negotiators. He used Macaozinho in Swahili.
“Macaozinho is incredible, and the world needs to know about it. It needs to be shared with all negotiators,” said Mohamed Nasr, Egyptian ambassador and leader of the COP27 presidency. Used in Arabic.
Macaozinho is part of Route to Belém, a partnership between the UNDP (United Nations Development Programme) and the Brazilian Ministry of Foreign Affairs’ Secretariat for Climate, Environment and Energy to support Brazil’s presidency of COP30 and democratise discussions on global climate change.
