According to its website, the CO2 Coalition exists to educate "thought leaders, policy makers, and the public about the important contribution made by carbon dioxide to our lives and the economy.” “CO₂ is not a pollutant. Rather, CO₂ is essential and beneficial for life on Earth,” Soepyan said.

In contrast to Soepyan’s comments, Eric Feely of the Oregon Department of Environmental Quality said: “The evidence that EPA is relying on to refute the scientific arguments behind the greenhouse gas engagement finding is well outside the mainstream consensus.”
