Climate Action Against Disinformation (CAAD) Report: “Misinformation around climate change and disinformation fueled by the fossil fuel industry have stalled climate action for decades. Big Tech has become a complicit actor in climate denial’s resurgence—so much so that the International Governmental Panel on Climate Change publicly called out the problem in 2022. In addition, the United Nation’s Policy Brief for Information Integrity on Digital Platforms in June of 2023 explicitly states that: “Mis- and disinformation about the climate emergency are delaying urgently needed action to ensure a liveable future for the planet.” Over the past several years, platforms have announced some policies to stop the spread of false climate content. In 2021, Google pledged to no longer allow the monetization of climate denial content on YouTube. In early 2023, TikTok added climate to its existing mis- and disinformation policies. In 2022, Pinterest took the largest step, banning climate misinformation in both organic content and advertisements. Nevertheless, research from environmental and civil society groups shows that there are serious gaps in the way that policies targeting climate misinformation are written and enforced. The purpose of this scorecard is to assess the policies of five major platforms that should aim to reduce the spread of climate mis- and disinformation. We’ve scored and ranked Meta (Instagram and Facebook), TikTok, Twitter/X, YouTube, and Pinterest in accordance with the standards set by the Climate Action Against Disinformation Policy Demands and “In the Dark”, our transparency-focused scorecard from 2022. We call on platforms to review our rankings and use them to guide future policymaking around stopping the spread of climate denial, greenwashing, hate speech, and public health misinformation.”
