During the first four weeks of stay-at-home orders, ozone pollution across Texas dropped by an average of 18%, as people stayed at home and drove less, according to a study from the Houston Advanced Research Center in The Woodlands. Researchers at HARC compared pollution levels from this year with average ozone levels during the
same period over the past six years to account for factors like weather, which plays a role in forming ozone.
