This updated EU DisinfoLab assessment reviews publicly available policy documentation from six platforms — Facebook, Instagram, YouTube, TikTok, X and LinkedIn — focused on how each addresses climate-related misinformation, without independently monitoring actual disinformation content on the platforms.
It finds that TikTok is the only platform with a dedicated, climate-specific content moderation policy, while the others rely on general misinformation frameworks or lack relevant structures altogether; YouTube has also declined to onboard third-party fact-checkers under DSA requirements. The report further notes that Meta's previously documented Climate Science Center and Climate Info Finder are no longer publicly referenced as of 2025, suggesting a rollback of prior climate-specific resources, and that no platform addresses AI-generated climate disinformation or examines recommender-system amplification of such content, nor treats climate risk as part of DSA Article 34(1)(c) systemic-risk audits.
It concludes that climate disinformation remains largely unregulated under the current DSA framework and calls for its formal designation as a systemic risk alongside more transparent, climate-specific moderation systems across platforms.
