Green Options

Last night Keilly Witman from EPA’s GreenChill Advanced Refrigeration Partnership, the program that attempts to get grocery stores to reduce ozone-killing refrigerant leaks, talked at EcoTuesday in DC. What I thought might not be our most exciting topic turned out to be one of the most interesting I’ve heard in the 8 months of co-hosting these events.

Ozone-depleting refrigerants are also potent greenhouse gases. One pound of the most commonly used HFC refrigerants has the same impact as about 4000 lbs of CO2. This is why Witman calls the reduction of refrigerant leaks the low-hanging-fruit of emissions control. There are 35,000 supermarkets in the US and each typically carries about 4000 lbs of refrigerant and leaks about 25% of that.  So, you do the math: 1000 lbs of high global warming gas from each of 35,000 supermarkets = 35,000,000 lbs leaked each year.  And its pretty simple and cheap to cut that number in half, which is where most GreenChill partner markets come in.

According to a 2008 GreenChill press release:

Compared to the rest of the supermarket industry, GreenChill partners are already emitting fewer ozone-depleting refrigerants and greenhouse gases than their competitors, and saving money at the same time. The partners’ savings in operating costs equal almost $13 million.

If every supermarket in the nation joined GreenChill and reduced their emissions to the current GreenChill average, the industry could prevent the release of 13 million metric tons of carbon dioxide equivalent and 157 ozone-depleting potential tons annually.

GreenChill has about 30 supermarket partners.  Let’s start applying the Big Green Purse principle and ask: Is your market a Greenchill partner or should you shop elsewhere?

Too many old yogurt containers concealing ancient leftovers in your refrigerator? Seems that we all have a stack of them cluttering the cabinets in our kitchen–the price we pay for enjoying yogurt, sour cream or anything that comes sold in those shiny Number 5 plastic containers and also having a conscience.

Luckily Preserve, makers of 100% recycled personal care products, has started a new program to recycle the pesky plastics even when your municipality does not. They’ve partnered up with organic dairy producers, Stonyfield Farm and Organic Valley, to turn used plastic dairy containers into toothbrush handles. Consumers can return the plastic containers, along with used Brita water filters, into bins at any of the participating Whole Foods markets in the Midwest, Northeast and Northern California.

“Cows aren’t Legos,” explains Jerri Cook, an organic dairy farmer and writer from the Wisconsin northwoods. “You can’t just rearrange genetic parts and expect it to be a cow anymore.”

Cook, along with her husband, Wayne, currently milk a herd of 25 cows, selling their milk to Organic Valley Family of Farms, the largest farmer-owned organic cooperative in the country. She represents the rural renaissance of farming women today: smart, sassy, steadfastly committed to educating about the importance of sustainable agriculture — and still the kind of gal who would warmly welcome you into her farmhouse kitchen for coffee, cheesecake and conversation.

Farming organically for over twenty-five years, the Cooks represent a small but dedicated group of farmers who have operated under these principles for their entire agriculture career. “Wayne’s family always farmed organically, thanks to his independent grandparents who didn’t want any part in what they saw as the government pushing chemicals,” says Cook with a smile. “I grew up an army brat in Germany and never experienced conventional American agriculture. When you’re never exposed to chemical fertilizers and pesticides, the concept logically doesn’t make sense. We ourselves didn’t want to eat food laced with that stuff; why would we ever sell it to anyone else?”
