Carbon Monitor, an international initiative that provides estimates of daily CO2 emissions, worldwide emissions from aviation fell by nearly 50 percent last year — to around 500 million metric tons of CO2, down from around 1 billion metric tons in 2019. (Those numbers are expected to rebound, though the timing will depend largely on how long corporate and international travel remain sidelined.)

Some national parks located near cities served as convenient recreational escapes throughout the pandemic. At Cuyahoga Valley National Park, 2020 numbers exceeded 2019 numbers from March through December. At Great Smoky Mountains National Park, numbers surged after a 46-day closure in the spring and partial closures through August; between June and December, the park saw one million additional visits compared to the same time period in 2019.
