COVID-19 was declared a pandemic earlier this month causing industries across the world to shutdown and workers to stay home to avoid further contamination and spreading of the virus. This emergency shutdown has lead to lower air pollution levels around the world.

More than 60% of transportation emissions come from passenger vehicles in the U.S. This makes personal transportation the largest source of greenhouse gases.  "Boston University’s emissions database, first published in 2015 and updated this month with an additional five years of data, reveals that much of the increase in driving-related CO2 has occurred in and around cities."
