Twitter says it will no longer allow advertisers on its site who deny the scientific consensus on climate change, echoing a policy already in place at Google.

“Ads shouldn’t detract from important conversations about the climate crisis,” the company said in a statement outlining its new policy on Friday. There was no indication that the change would affect what users post on the social media site, which along with Facebook has been targeted by groups seeking to promote misleading claims about climate change.

The announcement coinciding with Earth Day came hours before the European Union agreed a deal requiring big tech companies to vet their sites more closely for hate speech, disinformation and other harmful content.
