Twitter will no longer allow “misleading advertisements” that “contradict the scientific consensus on climate change,” on its platform, the company announced Friday. Earlier this month, the Climate Disinformation Coalition called on Big Tech to confront climate denial, particularly Twitter, which performed the worst on its scorecard. Days later, Pinterest announced robust new community standards to protect users from climate misinformation, and former President Obama praised the company for doing so. That was perhaps the final push Twitter needed to announce, on Earth Day, that it has formalized rules prohibiting climate disinformation in advertising.

While existing policies against misleading advertisements already prevent climate denial ads in theory, Axios reported, Twitter is following in Google’s footsteps and heeding activist calls to formally address climate disinformation, earning it additional points on the Big Tech Disinfo scorecard. Michael Khoo, co-chair of the Climate Disinformation Coalition, called it “a welcome step forward in the fight against disinformation,” adding that now “companies like Meta must now take stronger action and stop being the last bastions of climate denial.” (Axios, Protocol, The Guardian, CNN, Washington Post $, AP, The Verge, Fox Business)
