Just in time for Earth Day, and for the sixth consecutive year, the Arbor Day Foundation has recognized Georgia Tech as a Tree Campus USA university.

For Hyacinth Ide, associate director of landscape services, the award reaffirms that Tech is doing something right.

“It highlights all the things we are doing that otherwise people would not know,” Ide said. “A beautiful tree canopy helps in recruiting students and faculty. Once they see the peaceful environment, they want to come in and know more about what we have [on campus].”

Fish living on coral reefs where carbon dioxide seeps from the ocean floor were less able to detect predator odor than fish from normal coral reefs, according to a new study.

The study confirms laboratory experiments showing that the behavior of reef fishes can be seriously affected by increased carbon dioxide concentrations in the ocean. The new study is the first to analyze the sensory impairment of fish from CO2 seeps, where pH is similar to what climate models forecast for surface waters by the turn of the century.

Major corporate executives and other thought leaders on the environment will converge at Georgia Tech Scheller College of Business at 4 p.m. on Thursday, May 1, to discuss “The Sustainability Advantage: The Art and Science of Creating Sustainable Value.”Hosted by the Center for Business Strategies for Sustainability (CBSS), the panel discussion in LeCraw Auditorium of Scheller College (800 West Peachtree Street) will feature:

A team of four students from the Georgia Tech developing a new electrical power grid technology with an Internet-like control architecture won the third annual ACC Clean Energy Challenge and the Department of Energy's $100,000 grand prize.

The Student Government Association is encouraging fellow student organizations to earn silver by going green through a new initiative called Silver Leaf certification.

The Silver Leaf program asks that student organizations commit to recycling at one event per semester. The Office of Solid Waste Management and Recycling provides recycling bins, so students must simply request a bin for their event in advance.

“The goal of the initiative is to change student behavior and promote overall sustainability practices,” said Rachit Kansal, co-chair of SGA’s sustainability committee.

The mobile app OneBusAway, which tracks public transportation in real time, now includes arrival times for MARTA trains in addition to the MARTA buses and Georgia Tech shuttles already featured in the app.

The Georgia Tech Earth Day Committee is now accepting submissions for its annual Leadership and Sustainable Initiatives awards.

Nominations are sought for individuals or groups who are making a positive environmental impact both on campus and beyond, either through a new initiative or a body of work. The deadline for nominations is Friday, March 7.

In January 2014, three distinguished faculty were named Brook Byers Professors:  Bert Bras (Mechanical Engineering), Marilyn Brown (Public Policy), and Elsa Reichmanis (Chemical and Biomolecular Engineering).

Art Ragauskas, professor in Georgia Tech’s School of Chemistry and Biochemistry, is the recipient of the 2014 TAPPI Gunnar Nicholson Gold Medal Award. The award is the highest honor that TAPPI can bestow upon an individual and will be presented to Ragauskas at the 2014 PaperCon Conference Awards Dinner in April.

The College of Architecture (CoA) at Georgia Tech is leading an initiative to build the Sino-U.S. Joint Laboratory for Ecological Urban Design (Eco Urban Lab) in Shanghai, in collaboration with College of Architecture and Urban Planning (CAUP) of Tongji University, a leader in China in the area of urban development and architecture.

Mikey Mulford (MBA 2007) wouldn’t have envisioned that the passion he developed for green business during his time at Georgia Tech would translate into working on projects related to oil and natural gas drilling.

As a young girl growing up in Turkey, Beril Toktay accepted water and air pollution as a fact of life. “It wasn’t until I went abroad that I saw how much better it could be,” says the professor of operations management at Georgia Tech Scheller College of Business.

Delivering liquid fuel to energy-hungry forward operating bases can be both costly to the U.S. military and risky to those who transport the fuel. For those reasons, the U.S. Department of Defense (DoD) wants to reduce liquid fuel consumption at these bases, by expanding the use of alternative energy sources and by improving energy efficiency.

Ford Motor Company, in collaboration with Georgia Tech, debuted a new solar car concept earlier this month at the 2014 International CES in Las Vegas.

Today’s cyber attacks aren’t just a threat to computer networks. Those with malicious intent can disrupt important infrastructure systems such as utilities and power grids.

The trick is to identify when such attacks are underway.

The Department of Energy has awarded the Georgia Tech Research Institute (GTRI) $1.7 million to help detect cyber attacks on our nation’s utility companies.

Scientists studying the atmosphere above Barrow, Alaska, have discovered unprecedented levels of molecular chlorine in the air, a new study reports.

Molecular chlorine, from sea salt released by melting sea ice, reacts with sunlight to produce chlorine atoms. These chlorine atoms are highly reactive and can oxidize many constituents of the atmosphere including methane and elemental mercury, as well activate bromine chemistry, which is an even stronger oxidant of elemental mercury. Oxidized mercury is more reactive and can be deposited to the Arctic ecosystem.

Georgia Tech is a consistent leader in campus environmentalism, most recently ranking first in the Atlantic Coast Conference for Waste Minimization in the 2013 Game Day Challenge.

Competition may have a high cost for at least one species of tropical seaweed.

Researchers examining the chemical warfare taking place on Fijian coral reefs have found that one species of seaweed increases its production of noxious anti-coral compounds when placed into contact with reef-building corals. But as it competes chemically with the corals, the seaweed grows more slowly and becomes more attractive to herbivorous fish, which boost their consumption of the skirmishing seaweed by 80 percent.
