Recent years have seen a rise in information-based environmental policies. This report focuses on a type of voluntary, information-based environmental policy – air quality alerts – by summarizing the recent research and contributing new findings.

Are greenhouse gases a cause for concern?

The U.S. Environmental Protection Agency (EPA), which is forcing Americans to spend billions of dollars per year to address ozone air quality, is actually making the situation worse.

In their smog studies, the Ontario Medical Associationand Toronto Public Health have crossed the Rubicon from science to fear-mongering and political activism.

Activists continue to present misleading accounts of air quality issues despite the decline of ozone smog levels.

During the last thirty years,most of the country has had several years that were cooler or wetter than 2004, but never have smog levels been anywhere near this low.

State regulators have resisted replacing their inspection programs with on-road testing, yetthere is no other means to more substantial, rapid, or inexpensive improvements in air quality.

Acloser look at the data reveals that high ozone levels are found to be occurring on weekends, when emissions of nitrogen oxides are often 40 percent lower than weekdays.
