This study uncovers substantial proof of a well-coordinated campaign by fossil fuel companies and their accomplices to spread climate disinformation and impede climate action. It uncovers seven “deception dossiers,” which comprise leaked internal documents that show deliberate attempts dating back several decades to sow confusion about climate science and hinder policies geared toward minimizing greenhouse gas emissions. The report highlights the similarity between the fossil fuel industry’s tactics and those previously employed by the tobacco industry, stressing the purposeful deception aimed at safeguarding profits at the expense of public and environmental health.
