This Declaration was launched during COP30 by the Global Initiative for Information Integrity on Climate Change, established by UNESCO, the Government of Brazil and the UN.
It establishes shared international commitments to address information integrity on climate change and promote accurate, evidence-based information on climate issues.
This endorsement comes at a time when the information environment can be difficult to navigate, especially on climate matters. According to the 2025 Eurobarometer on climate change, while 84% of Europeans agree that climate change is caused by human activity, 52% say traditional media fail to provide clear information on the topic, and 49% report difficulty identifying reliable content on social media.
By endorsing this Declaration, the European Union is demonstrating its firm commitment to factual debate, climate science, and evidence-based policymaking. Prior to the EU’s endorsement, fifteen EU Member States had also endorsed the Declaration individually: Austria, Belgium, Czechia, Denmark, Estonia, Finland, France, Germany, Luxembourg, Netherlands, Poland, Portugal, Slovenia, Spain, and Sweden.
Commissioner Hoekstra announced the EU’s endorsement of the Declaration, saying: “We’re living in a world where the threat of climate change is becoming ever more urgent and, at the same time, where alternative truths, confrontation and disinformation abound. This is cause for concern. Informed public debates where we listen and look at the science are so essential if humanity is going to effectively tackle the climate crisis.”
Climate Facts Matter: awareness-raising campaign on climate disinformation
As part of efforts to address the issue, the European Commission’s Directorate-General for Climate Action has launched the #ClimateFactsMatter campaign to empower people to see through climate disinformation. It will equip people across the EU with the information they need to make informed decisions. The campaign will share resources allowing everyone to spot the main techniques being used to mislead and highlight what the facts are about EU climate action.
