Average fuel economy (window-sticker values) of cars, light trucks, minivans and SUVs purchased in April was 23.9 mpg, down from 24.1 in March, but the same as in February. Despite the drop, fuel economy is up 3.8 mpg (or 19 percent) from October 2007, the first month of monitoring by UMTRI researchers Michael Sivak and Brandon Schoettle.
Three research teams affiliated with Iowa State University’s Bioeconomy Institute have won Iowa Energy Center grants to help them combine biorenewable technologies for better production of fuels and chemicals.
The city of Unalaska, Alaska, will undertake a major upgrade of its municipal sewage treatment plant under a settlement of a Clean Water Act enforcement action filed against the city and the state of Alaska by the Department of Justice on behalf of the Environmental Protection Agency.
The U.S. Fish and Wildlife Service today announced the extension of a public process exploring the expansion of incentives for voluntary partnerships with private landowners and other land stewards to help conserve imperiled wildlife.
Sculpted by chemistry graduate student Longzhu Shen (MCS'12), the latest installation at CMU's ArtPark Lab uses environmentally friendly lighting to illustrate the fluctuation of carbon dioxide levels in Earth's atmosphere over the past 800,000 years.
Every spring and summer, millions of Americans dread the trip to the park or the playground and will do anything to avoid activities that trigger outdoor allergies.
The Central Park Conservancy, an internationally recognized leader in park management and restoration, has been awarded a $500,000 grant from Alcoa Foundation and an in-kind donation of aluminum valued at $140,000 from Alcoa Recycling to design a sustainable waste management system to increase recycling and make trash removal in the Park more efficient.
The U.S. Environmental Protection Agency has determined that the systems used at gas station pumps to capture harmful gasoline vapors while refueling cars can be phased out. Modern vehicles are equipped to capture those emissions
Carbon nanotubes, which consist of atom-thick sheets of carbon rolled into cylinders, have captured scientific attention in recent decades because of their high strength, potential high conductivity and light weight. But producing nanotubes in bulk for specialized applications was often limited by difficulties in controlling the growth process as well as dispersing and sorting the produced nanotubes.
A 100-fold upsurge in human-produced plastic garbage in the ocean is altering habitats in the marine environment, according to a new study led by a graduate student researcher at Scripps Institution of Oceanography at UC San Diego.
Two University of Texas at Austin faculty members have won Moncrief Grand Challenge Faculty Awards to develop computer models for algae-based fuel production and improve the security of coastal waters.
The U.S. Environmental Protection Agency is seeking project proposals to reduce land-based trash at the source, thus preventing trash from entering coastal runoff and becoming marine debris.
It was all too evident during the Dust Bowl what a disastrous impact wind can have on dry, unprotected topsoil. Now a new study has uncovered a less obvious, but still troubling, effect of wind: Not only can it carry away soil particles, but also the beneficial microbes that help build soil, detoxify contaminants and recycle nutrients.
Toyota unveiled Monday what it says is the first all-electric sports utility vehicle (SUV) on the market, a version of its popular RAV4 with a top range of 100 miles and minimum six-hour charge time.
Changes in the speed that ice travels in more than 200 outlet glaciers indicates that Greenland's contribution to rising sea level in the 21st century might be significantly less than the upper limits some scientists thought possible, a new study shows.
The U.S. Environmental Protection Agency has released a draft underground injection control (UIC) program permitting guidance for class II wells that use diesel fuels during hydraulic fracturing activities.
A new National Research Council report says that budget shortfalls, cost-estimate growth, launch failures and changes in mission design and scope have left U.S. earth observation systems in a more precarious position than they were five years ago.
Biodiversity loss could impact ecosystems as much as climate change, pollution and other major forms of environmental stress, according to a new study by an international research team.
Carrington College's campus in Mesquite, Texas, has won the Leadership in Energy and Environmental Design (LEED) silver certification by the U.S. Green Building Council (USGBC).
Intense development of the two largest natural gas fields in the continental United States is driving away some wildlife from their traditional wintering grounds, according to a study by the Wildlife Conservation Society.
