Charter for Climate Information Integrity in Advertising
Charter for Climate Information Integrity in Advertising
Supporting the commitments of the Belém Declaration on Information Integrity on Climate Change.
Developed by Conscious Advertising Network (CAN), with the support of the Global Initiative for Information Integrity on Climate Change, the Charter for Climate Information Integrity in Advertising responds to international calls, including the UN Global Principles for Information Integrity (2024), to harness the power of advertising to support healthy information environments, uphold human rights and strengthen access to accurate, evidence-based climate information.
About the Charter
Digital advertising is a major source of funding for today’s information ecosystem.
Yet the technologies and business models behind it can also contribute to the spread and monetisation of climate misinformation and disinformation, while raising significant concerns around transparency, accountability and human rights.
The Charter describes the risks advertising poses to climate information integrity and offers key principles to inform, interpret and implement policies and practices to mitigate those risks.
Addressing State actors and advertisers, it provides practical measures to strengthen climate information integrity across the advertising ecosystem, in line with existing international human rights obligations and commitments.
Supporting the commitments of the Belém Declaration
Launched at COP30 in 2025 by the Global Initiative for Information Integrity on Climate Change, a multi-stakeholder coalition co-led by the Government of Brazil, the United Nations and UNESCO, the Belém Declaration recognises the importance of information integrity for climate action.
The Declaration calls on the private sector to commit to information integrity on climate change in its business practices and to ensure transparent, human rights-responsible advertising practices that support reliable information and journalism.
The Charter provides a delivery mechanism for the commitments made in the Declaration, translating them into principles, policy priorities and recommended practices for State actors and advertisers.
Five interrelated areas for action
The Charter identifies five areas of action to address the risks advertising poses to climate information integrity:
01
Human rights safeguards for freedom of opinion and expression, as well as the right to privacy
02
Healthy incentives for information integrity on climate change
03
Transparency of digital advertising supply and value chains
04
Safeguarding against greenwashing in advertising practices
05
Accountability for harm to climate information integrity
Across these areas, the Charter outlines policy priorities and practices aimed at strengthening transparency, accountability and human rights safeguards across the advertising ecosystem.
