NASA Finds Local Lockdowns Brought Global Ozone Reductions

As the coronavirus pandemic slowed global commerce to a crawl in early 2020, emissions of nitrogen oxides (NOx) – which create ozone, a danger to human health and to climate – decreased 15% globally with local reductions as high as 50%, according to a study led by scientists at NASA's Jet Propulsion Laboratory. As a result of the lower NOx emissions, by June 2020 global ozone levels had dropped to a level that policymakers thought it would take at least 15 years to reach by conventional means, such as regulations.
