LONDON —

       Google is taking action to stop climate change deniers from spreading misinformation or making money on its platforms by blocking digital ads alongside such content and banning ads that promote false climate change claims.

       The company said Thursday in a blog post that it was rolling out a new policy for YouTube video creators. advertisers and publishers.

       The new rules “will prohibit ads for, and monetization of, content that contradicts well-established scientific consensus around the existence and causes of climate change,” the blog post said.

       The rules will apply to any content calling climate change a hoax or denying that greenhouse gas emissions and human activity have contributed to the Earth’s long-term warming.

       The aviation pause during the COVID lockdowns accounted for 10% of the decrease in global emissions, research found. Five of the 10 largest buyers of corporate air travel in the U.S. are technology companies.

       “In recent years, we’ve heard directly from a growing number of our advertising and publisher partners who have expressed concerns about ads that run alongside or promote inaccurate claims about climate change,” Google’s ad team said.

       The company said advertisers don’t want their ads appearing next to content denying climate change, and publishers and creators don’t want them appearing on their pages or videos.

       Google said it would use both automated tools and human reviewers to enforce the policy when it takes effect in November.

       Earlier this week, Google rolled out new features aimed at helping users reduce their carbon footprints, including a search function that shows which flights have lower emissions.
