Green Grid Radio founder, producer and engineer Adam Pearson started on the music side of radio during his freshman year at Stanford University, but as his studies and interests in environmentalism picked up, he aligned his programming focus and started the show in September 2012. Now the program is recorded live on Stanford’s KZSU radio station and podcasted online.

Pearson recalls, “I have this toolset available, and I decided I needed to do something meaningful. Green Grid Radio’s mission is all about engaging and transformative narratives regarding the environment, energy, and sustainability.”

Kevin Campbell, Manager of Fleet Services at the City of Chicago’s Department of Fleet and Facility Management, aims to conserve across a network of more than 3,000 police vehicles, 500 garbage trucks, 300 salt-spreader trucks, 125 street sweepers and 100 ambulances — a total fleet of more than 12,000 vehicles. A handful of measures, from idling standards, to drastic nitrogen-oxide emissions reductions, keeps this massive fleet from heavily polluting Chicago’s air supply.

“Motor vehicles account for nearly half of air pollutants,” Campbell says. “Anything we can do to reduce [the City of Chicago's] output is pursued aggressively.”

World-class environmental photographer Daniel Beltrá began taking pictures as a childhood hobby in his native Madrid, Spain, before his talent evolved into a way to highlight his passion for nature. Now based in Seattle, Beltrá has traveled the globe, snapping pictures of everything from the most remote forests to the tragic realities of the BP oil spill.

“Definitely, there are harsh moments. I see things that are not pleasant,” Beltrá admits. “But I feel the power of photography. It is something that transcends me.”
