Google and YouTube on Thursday announced a new policy that prohibits climate deniers from being able to monetize their content on its platforms via ads or creator payments.

Why it matters: It's one of the most aggressive measures any major tech platform has taken to combat climate change misinformation.

Details: Google advertisers and publishers, as well as YouTube creators, will be prohibited from making ad revenue off content that contradicts "well-established scientific consensus around the existence and causes of climate change," the company's ads team said in a statement.

"This includes content referring to climate change as a hoax or a scam, claims denying that long-term trends show the global climate is warming, and claims denying that greenhouse gas emissions or human activity contribute to climate change."
