If you are concerned about ozone, when there is an ozone warning, you can avoid going outside and stay inside in an air-conditioned building. I would tell people not to run outdoors on those days in the afternoon. Just try to change your schedule. Ozone is a very reactive compound. When you bring it indoors, it reacts with your carpet and everything it comes into contact with in your home, including air conditioning.
Indoor air has minimal ozone.
It depends on which way the wind is blowing. The worst is when there is stagnation. They are coming up with ideas for legislation on vehicles and industries. But there is a feeling now that it's been pushed back enough, and we need serious air-quality solutions. If we don't meet air-quality standards by that date, there will be serious consequences.
