The Brazilian government, the United Nations and Ä¢¹½ÊÓƵESCO are joining forces to strengthen research and measures to address disinformation campaigns that are delaying and derailing climate action.

The aims to boost support for urgent climate action and to show that solutions exist and are already working.

Announced at the G20 Leaders Summit in Rio de Janeiro in November 2024, the Initiative is a dedicated multilateral collaboration among States and international organizations to fund research and action promoting information integrity on climate issues.

Aiming to expand the scope and breadth of research into climate disinformation and its impacts, the effort will gather evidence from around the world, with a focus on the Global South and languages other than English, to inform and bolster strategic action, advocacy and communications.

The Initiative responds to the commitment in the Global Digital Compact, adopted by United Nations Members States at the Summit of the Future in September 2024, which encourages Ä¢¹½ÊÓƵ entities, in collaboration with Governments and relevant stakeholders, to assess the impact of mis- and disinformation on the achievement of the Sustainable Development Goals.

As part of the Initiative, a Global Fund has been created to finance networked, in-depth research that contributes to exposing and dismantling disinformation related to climate change, as well as sharing what it finds. The Fund is administered and implemented by and is structured as a Multi-Partner Trust Fund. Its first call drew over 500 proposals from around 100 countries, mostly from the Global South, requesting about USD 40 million against a USD 1 million fund.

The Initiative supports and strengthens existing communications campaigns on climate change to mitigate and counter climate disinformation. It also supports ongoing advocacy and communications to strengthen the integrity of information environments globally and works to garner support from civil society and scientific groups worldwide.

Among those who have joined the Initiative are Ä¢¹½ÊÓƵ Member States (Australia, Belgium, Brazil, Canada, Chile, Colombia, Denmark, Finland, France, Germany, Morocco, Netherlands, Peru, Spain, Sweden, the United Kingdom and Uruguay), Ä¢¹½ÊÓƵ entities (, the ), the Organisation for Economic Co-operation and Development (), and civil society representatives.

At the 30th Ä¢¹½ÊÓƵ Climate Conference in Bel¨¦m, Brazil, in November 2025, the final recognized that information integrity is essential for effective climate action. This marks the first time that information integrity has been formally embedded in international climate governance and establishes a foundation for coordinated international action on information integrity.

New at COP31

Charter for Climate Information Integrity in Advertising. The Charter asks advertisers to demand transparency, take back control of where their ads are placed and support reliable journalism. It is a key outcome for implementing the Declaration.

Priorities for Action on AI for Climate Information Integrity. The Priorities set out what AI actors, advertisers, States, researchers and funders can do now to close two gaps. Information from AI: tools can make false claims sound convincing and serve many languages poorly. Information about AI: communities lack data on the energy, water and land use of AI infrastructure, and claims about AI¡¯s climate benefits go untested. The Global Initiative will report progress at the Global Dialogue on AI Governance and at COP32.

Ä¢¹½ÊÓƵ Global Principles for Information Integrity

The Initiative draws on the United Nations Global Principles for Information Integrity as an important framework for action. Its work is grounded in human rights and freedom of expression: tackling disinformation and protecting free speech go hand in hand.

The Principles envision an information ecosystem that delivers choice, freedom, privacy and safety for all, in which people everywhere can express themselves freely and make informed and independent decisions.

They put forward proposals to empower people all over the world by handing them greater control over the media they choose to consume, their own online experiences, and how their personal data is used.

The principles offer support to all those working to share facts in the public interest, as well as the vulnerable or marginalized voices that so often bear the brunt of targeted disinformation and hate campaigns.
