450+ Scientists' Letter to Agencies: Drop Fossil Fuel Clients

A collective statement by over 450 scientists calling on PR and advertising agencies to drop fossil fuel clients, arguing that industry misinformation campaigns are a primary barrier to necessary government climate action.

• Scientists identify advertising and PR efforts by fossil fuel companies as a significant obstacle to government action required for climate mitigation, noting these campaigns "seek to obfuscate or downplay our data and the risks posed by the climate crisis."
• The signatories state that carbon pollution must be reduced by nearly 50% within the current decade and eliminated entirely by 2050, necessitating a "rapid transition away from all fossil fuels."
• The letter demands that coal, oil, gas, and electricity companies immediately begin transitioning to a zero carbon future.
• The authors call on PR and advertising agencies to take four specific actions: drop clients planning to expand oil and gas production, end relationships with companies and trade groups that engage in climate deception, stop work that obstructs climate legislation, and promote existing climate solutions.
• The document concludes with a direct demand that all public relations and advertising campaigns supporting fossil fuels must end.
