The company stated that ads shouldn’t distract from important conversations about climate crisis in Friday’s statement.

It was not clear that the change would impact what users posted on the social media site. Facebook, along with other sites, has been targeted by groups trying to spread misleading climate change claims.

Hours before the European Union reached a deal that requires big tech companies to screen their websites more carefully for hate speech and disinformation, the announcement coincided with Earth Day.

Twitter stated that it will provide additional information over the next months on how it plans “reliable, authoritative context for the climate conversations” it users engage in, as well as from the Intergovernmental Panel on Climate Change. International negotiations to stop climate change will be based on the U.N.-backed science panel reports that examine the causes and consequences of climate change.

The company already had a climate topic on their site, and it offered “pre-bunks,” during the U.N. climate conference last year to counter misinformation about climate change.
