In 2009, the EPA ruled, under the Clean Air Act, that “the current and projected concentrations of the six key well-mixed greenhouse gases—carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6)—in the atmosphere threaten the public health and welfare of current and future generations.” In essence, the EPA classified carbon dioxide as a pollutant even though Carbon dioxide is necessary for life on Earth.
For some perspective, note that current atmospheric concentration of carbon dioxide is about 400ppm (parts per million) while the air we exhale with every breathe contains 40,000ppm carbon dioxide. Is breathing causing air pollution?
This EPA ruling in effect allowed EPA to regulate everything from automobile exhaust to power plants to refrigerators. In order to overturn the finding, one would have to successfully show that the underlying scientific basis is wrong – and it is. Another tactic would be to have Congress amend the Clean Air Act, something that is very unlikely in the current contentious Congress.
The EPA’s scientific basis is derived from climate models, predictions of which diverge widely from reality. See my ADI articles:

The EPA CO2 endangerment finding endangers the USA by Dennis Avery.
“In science, if your theory doesn’t take account of all the relevant data, you need a new theory.” Avery shows how the climate models fail to explain observations and notes that thousands of new coal-fired power plants are being built around the world – even in Europe. Avery is a former U.S. State Department senior analyst and co-author with astrophysicist Fred Singer of Unstoppable Global Warming: Every 1,500 Years.

“Revoking the EF is the only way to bring the climate alarmism scam to the untimely end it so richly deserves in the US and hopefully indirectly elsewhere. Until that happens the CIC [climate industrial complex] will continue to pursue its bad science through reports such as the National Climate Assessment with the recommended disastrous policies that would seriously damage the environment, impoverish the less wealthy, and bring economic disaster for our Nation by raising the prices and decreasing the availability and reliability of fossil fuel energy which is so central to our way of life and economy.”
In a separate post, Carlin also said that “EPA never engaged in a robust, meaningful discussion. Rather, there was a pro forma review after a decision had already been made which met many but not all of the legal requirements.” He lists “six crucial scientific issues that EPA did not actively discuss despite my best efforts to bring a few of them to their attention in early 2009.”

“We the undersigned are individuals who have technical skills and knowledge relevant to climate science and the GHG Endangerment Finding. We each are convinced that the 2009 GHG Endangerment Finding is fundamentally flawed and that an honest, unbiased reconsideration is in order.”
