On the Road with CNG

What we learned driving a bi-fuel van from North Carolina to Connecticut

CNG fill-up

Earlier this year, Piedmont Natural Gas generously donated a bi-fuel van, meaning it runs on Compressed Natural Gas (CNG) and gasoline, to the Sustainable America fleet. We were thrilled to have the 2002 Chevy 2500 Express Passenger Van to use in our alternative fuel programming and educational outreach, but first we had to drive it from Charlotte, N.C., back to our headquarters in Stamford, Conn. Here’s how it went…

12 Ways to Make Your Next Party More Sustainable

Make memories, not waste

Pumpkins and hay bales make great natural party decorations

When my daughter celebrated her bat mitzvah this fall, we were incredibly proud of her accomplishments and poise, but also pleased with her choices to make the reception a sustainable one. Weddings, funerals and rites of passage like bar mitzvahs and confirmations can generate a tremendous amount of waste, but with a little forethought, these celebrations can be meaningful, fun and sustainable.

7 Technologies That Can Slash Idling

Annoyed by vehicles idling in your area? These solutions can help clear the air.

tailpipe exhaust fumes

We’ve been known to get more than a little irked when we notice people idling their vehicles unnecessarily, like at drive-thrus or school pick-ups. It wastes gas, it pollutes the air, it stinks and it’s just, well, unnecessary. But some drivers get a free idling pass, right? Don’t refrigerated trucks, utility vehicles, safety and emergency vehicles and long-haul trucks often need to keep their engines running to power auxiliary functions? Yes, and no. Here, we explain.

An Investment in Organic Farmland

Farmland LP is working to make organic farming a sustainable, profitable business for farmers and investors

Chickens grazing on pasture at a Farmland LP farm

A road trip to Oregon farmland crystalized a new business idea for partners Craig Wichner and Jason Bradford. “It was very clear farmland was a great asset and that it was basically being underutilized,” says Wichner, “that growing monocrops was operationally efficient, but it was the worst way to get returns from farmland itself.” With investment and the use of sustainable agriculture templates, they developed Farmland LP, a system of livestock, vegetable and grain rotations that could both reclaim land for organic farming and turn a profit.

Darien High School Fuel Cell Team's car

We’re inspired by a group of high school students in Connecticut who are building their own hydrogen fuel cell electric vehicle — a project that has been in the works for a decade. There’s just one catch: They need to raise money for a new fuel cell in time to compete at the Shell Eco-Marathon in April. Learn more about these enterprising kids and how to support their project.

Turnip greens

One of my favorite things about participating in a CSA program is learning about new foods. This year’s most pleasant surprise was sweet potato greens. Our very own farmer didn’t realize these beautiful greens were edible until this year, and boy were we happy that he shared his newfound secret!

A new initiative to reduce energy use, water use and transportation emissions

Adventures in Indoor Growing

We get down and dirty with vertical gardening, aquaponics and hydroponics

lettuce, basil and chives

Over the last few months, we’ve been experimenting with a menagerie of indoor food-growing systems at our office: a vertical garden, a hydroponic system and an aquaponic system. While the versions we’ve installed won’t revolutionize the local food landscape in our neighborhood, if scaled up, these alternative growing methods have the potential to help urban areas meet the growing demand for food. We wanted to get hands-on with a few of these methods to learn more and to provide a showcase of what’s possible. Here’s how we did…

We Came, We Gleaned, We Fed Thousands

'Feeding the 5,000' rescued food, raised awareness about food waste

Volunteers for Feeding the 5000: Oakland
