Vehicle emissions in Wisconsin declined temporarily during COVID-19 shutdowns

Quoted: Power plant and industry emissions didn’t see a steep drop or any decline during stay-at-home orders. The findings are consistent with what one would expect to see from people traveling less during the pandemic, said Tracey Holloway, professor with the Nelson Institute of Environmental Studies at the University of Wisconsin-Madison.

“They did not see that much of a change in pollution from power plants and some industries, and that also is consistent because we’re still using electricity,” said Holloway. “We’re still running our air conditioners and the kind of things that drive a lot of demand for electricity were still happening.”
