Misinformation is the sharing of false or selectively presented data about fossil fuel emissions and climate change, influencing public perception of the issue. It can result from mere mistakes or misunderstandings. Greenwashing, a deceptive tactic used by businesses, exaggerates their environmental credentials while ignoring their actual impact. Disinformation, on the other hand, involves the deliberate dissemination of false information and hoaxes by climate deniers and certain organizations for their own agenda. Major fossil fuel companies and astroturfing groups are also involved in discrediting climate science. Media outlets and populist politicians contribute to the spread of misinformation as well. Social media and conspiracy theories further amplify the reach of false information. Climate misinformation is detrimental to tackling climate change as it hampers public support and casts doubt on proven solutions. The deliberate undermining of science and the promotion of misinformation have contributed to misperceptions and disregarding the urgency of climate action. Various advocacy groups, governments, and international organizations are actively countering climate misinformation through awareness campaigns and fact-checking initiatives.
