CNN, CNN International, CNN.com, and Headline News are indispensible sources of trusted information for tens of millions of Americans. Yet CNN accepts and regularly runs propagandistic advertisements from the fossil-fuel industry looking to greenwash their responsibility for the destruction of our climate. This conflicts with CNN's mission and offers a jarring disconnect to the work CNN's journalists are doing to honestly report the heat waves, storms, droughts, wildfires, and other deadly chaos caused by the oil, gas, and coal industry's greenhouse pollution. Furthermore, these advertisements are part of a deliberate, decades-long campaign by the industry to subvert our political system and deceive the public about the dangers of their highly profitable product.

As atmospheric carbon dioxide levels pass 420 parts per million and the CO2-equivalent of all greenhouse pollution passes 450 ppm, now is the time for CNN to stop accepting advertisements from the fossil-fuel industry.
