UN Secretary-General António Guterres has once again sharpened his criticism of the fossil fuel industry and called for a ban on fossil fuel company advertising. „I urge every country to ban advertising from fossil fuel companies,“ Guterres said in a speech on June 5, International Environment Day. After all, governments already ban advertising for products such as tobacco that are harmful to health. „And I urge news media and tech companies to stop taking fossil fuel advertising,“ he added.
