UNIVERSITY PARK, Pa. – Burning fossil fuels has long powered world economies while contributing to air pollution and the buildup of greenhouse gases. A new analysis of nearly two decades of satellite data shows that economic development, fossil-fuel combustion and air quality are closely linked on the continental and national scales, but can be decoupled at the national level, according to Penn State scientists.

“We know air pollution and economic development are linked, but we want to know how tightly and whether our actions can change this,” said Ruixue Lei, a post-doctoral researcher in the Department of Meteorology and Atmospheric Science. “We found they are not inherently bonded and can be decoupled under favorable policies.”
