Study examines how clean air act affects municipal bond market

Credit: Unsplash/CC0 Public Domain Research has studied the effects of climate risk on financial markets, but few studies have addressed the effect of environmental policy on those markets. A new study examined whether federal policy aimed at mitigating local air pollution—specifically, the Clean Air Act—affected the municipal bond market from 2005 to 2019. The study […]

Researchers measure, model desalination membranes to maximize flow, clean more water

Controlling the nanoscale structure of membranes is key for clean water, researchers find

UNIVERSITY PARK, Pa. — A desalination membrane acts as a filter for salty water: push the water through the membrane, get clean water suitable for agriculture, energy production and even drinking. The process seems simple enough, but it contains complex intricacies that have baffled scientists for decades — until now. Researchers from Penn State, The […]

Affordable Clean Energy Rule Threatens Progress of Clean Air Act

Last year, the U.S. EPA finalized the Affordable Clean Energy (ACE) rule, a dramatic relaxing in air pollution standards. ACE effectively rolls back the Obama administration’s Clean Power Plan (CPP), policy that aimed to reduce carbon emissions from U.S. electrical power generation—in particular, from coal-burning power plants—through the first national standards. ACE instead […]
