Professor Kevin Gurney of NAU’s School of Informatics, Computing and Cyber Systems measures greenhouse gas emissions in major US cities. He says the consumption of three important fuels has made a nose-dive: gasoline, jet fuel and distillate (diesel).

“For the first three weeks of April, gasoline has declined 43.1%, jet fuel by 59.3% and diesel fuels by 16.7% compared to the same three weeks over the last decade,” Gurney said. “If you didn’t know any better, you’d think it was an error in the data. Nothing like this has ever shown up in the record. Never.”
