Greenhouse gas (GHG) emissions have been reduced by an accumulated 5.7 million metric tonnes (mt) in Mexico City since it began implementing its Green Plan in 2008, the Mexico City government recently announced.
In a paper published in the journal Nature Climate Change, researchers from CSIRO, University of Queensland and United States Geological Survey present a pragmatic decision framework for determining when, if ever, to move species in the face of climate change.
An old theory in ecology is that in any ecosystem, a small-sized animal species will be more populous than a large species. All you need is a summer picnic to prove the point: your barbecue might end up attracting thousands of tiny ants — but only a few rotund squirrels.
A recent increase in the abundance of particles high in the atmosphere has offset about a third of the current climate warming influence of carbon dioxide (CO2) change during the past decade, according to a new study led by NOAA and published today in the online edition of Science.
U.S. Department of Agriculture scientists have produced the first detailed data on how large-scale dairy facilities contribute to the emission of greenhouse gases.
Experts at The University of Texas at Austin and the Cockrell School of Engineering are helping to improve the safety and efficiency of hydraulic fracturing, identify issues that need to be corrected and untangle the knowns and unknowns of a process that is expected to constitute perhaps half of the nation's total natural gas supplies in coming years.
A settlement between the United States and the Jersey City, N.J., Municipal Utilities Authority will resolve Clean Water Act violations by JCMUA for failing to properly operate and maintain its combined sewer system, the Department of Justice and the EPA.
Scientists from The University of Manchester have been selected to undertake vital safety work on the next generation of the world’s nuclear reactors.
Two University of Alberta researchers have published a step-by-step plan to one day end the use of environmentally harmful chemicals on commercial crops by developing plants that produce their own fertilizer.
Understanding how energy can be used efficiently is key to reducing carbon emissions and mitigating future fuel and food shortages. But energy use is only part of the story. The link between resources and final services – such as food, warmth, shelter and transport – is only really complete if water and land use is also factored in.
Gabriel Henson, a supervisor for Integrated Production Services Inc., a Houston-based natural gas and oil drilling contractor, pleaded guilty to a negligent violation of the Clean Water Act in federal court in Muskogee, Okla.
As the demand for energy increases worldwide, the search for renewable and viable sources of power intensifies.
Surface water quality is important for the proper function of aquatic ecosystems, as well as human needs and recreation. Pasturelands have been found to be major sources of sediment, phosphorus and pathogens in Midwest surface water resources.
The wildfires currently raging in the southwestern United States bring issues of land management into the public eye. Land management actions, such as prescribed fire, grazing, herbicides, felling trees and mowing, can restore native plants and reduce wildfire. However, the public’s view of land management and their trust in land management agencies can pose another obstacle.
The U.S. Environmental Protection Agency (EPA) recently released final guidance on Appalachian surface coal mining, designed to ensure more consistent, effective, and timely review of surface coal mining permits under the Clean Water Act and other statutes.
Darden School of Business Professor Andrea Larson has tapped into an efficient and greener way to bring low-cost, high-quality scholarly material on sustainability to instructors and students.
Rural landscapes of the future might have pyrolysis plants instead of grain elevators on every horizon —processing centers where farmers would bring bulky crops such as switchgrass to be made into crude oil.
After collecting weathered crude oil from the Gulf of Mexico following the Deepwater Horizon oil spill, researchers at Texas Tech University have reported that only 8 to 9 percent coverage on the shells of fertilized mallard duck eggs resulted in a 50 percent mortality rate.
The U.S. Environmental Protection Agency (EPA) recently awarded a $300,000 environmental workforce development and job training grant to Santa Fe Community College (SFCC) to promote green jobs in Santa Fe, N.M.
Tanner industries, which distributes ammonia, has agreed to install and operate $345,000 in ammonia leak detection systems at 14 facilities across the country to settle claims by the U.S. Environmental Protection Agency that it violated federal clean air regulations on chemical risk management at plants in Rhode Island and Michigan.
