That flexibility should be preserved if the federal government moves to centralize airemissions policy under a new Clean Air Act. One simple way of doing this would be to grandfather existing provincial regulations in all regions that currently comply with National Ambient Air Quality Objectives for SO2, CO, TSP, ozone, and NO2, so that regions already complying with clean air rules are exempt from any new rule-making at the federal level. This reflects the simple principle of building on success, rather than punishing it.
There is some evidence that VOC emissions matter more than NOx emissions for limiting ozone levels. But, until the matter is better understood, it would be unwise to promise major reductions in ground-level ozone levels. The Canada-wide standard for ozone, discussed above, is a noble goal but we should not be too surprised if it is not readily achievable, especially since ozone is sensitive to the intensity of solar flux and we are near the start of a new solar cycle (NASA, Marshall Space Flight Center, Solar Physics Group, 2006).
