Researchers at the University of South Australia are calling for a major shift in how cities manage tree root intrusions into household sewer systems that cost millions of dollars in repair bills each year.

Low carbon fuel policies are intended to reduce greenhouse gas (GHG) emissions from transportation. However, rigid carbon intensity (CI) accounting procedures in current policies may limit CI responsiveness across candidate sites and facilities. This study examines how low carbon fuel programs capture or overlook spatial variability and net electricity production in biofuel carbon intensity, influencing crediting outcomes and fuel selling prices.

A new study shows how extreme weather and power outages can impact socially vulnerable populations in counties near the U.S. Gulf Coast. The researchers also estimated the 10 counties most and least likely to have long-term power outages in the five states that border the Gulf.
