Ozone levels across much of North America and Europe dropped significantly between 2000 and 2014. People living in parts of southern Europe, South Korea and southern Japan and China also experienced more than 15 days a year of ozone levels above 70 ppb. Source: University of Leicester.

Further, the agency said, technical progress has been made in developing technologies and approaches that can reduce NO x emissions beyond the standards put in place in the 2000 rule. (In the final HD Phase 2 rule, EPA had noted the evidence supporting the need for more stringent national NO x emissions standards.).
