It’s a carefully compiled shopping list.
You pay attention to food miles so there’ll be no out of season raspberries. Chilean sea bass is on the Seafood Watch List so you’ll choose local cod instead. You want your eggs cage free, you want milk without rBST, and beef that’s free of antibiotics. And of course you’ll look for lots of organics.
You steer the Prius into a parking space and grab the reusable grocery bags you brought with you.
You’re ready to shop.
Are supermarkets merely talking the talk?
Supermarkets have done a good job of helping consumers integrate sustainable choices in their daily lives. They’ve been far less successful when it comes to their own environmental impact. There are 36,000 supermarkets across the United States. Some recycle, some are energy efficient, some limit their food waste, and some mitigate their greenhouse gas emissions; very few have managed to piece all the bits of the sustainability puzzle together.
With their blazing lights, doorless freezers, and open refrigerator aisles, supermarkets are almost always the biggest energy guzzlers around, using twice as much as energy as the average commercial building per square foot. According to the U.S. Energy Information Administration (EIA) only hospitals and restaurants are more energy-intensive. The electricity and natural gas used by the average supermarket annually dumps 1,900 tons of CO2 into the atmosphere. It’s as if they filled the space with 372 cars and ran the engines all year.
Worst of all are the walk-in coolers, refrigerators, and freezer cases. These are the nation’s single biggest source of hydrofluorocarbons (HFC), emissions that are 4,000 times more powerful in causing climate warming than carbon dioxide. While shoppers have been educated to bring reusable bags or to choose paper over plastic—even banning disposable plastic bags in many cities and towns—the EIA reports that HFC greenhouse gases from supermarket refrigerators and freezers pose just as great a threat to the environment, yet few stores have been fitted with greener equipment.
What’s good for the goose..
More and more consumers are doing their part. It’s time for supermarkets to step up their own sustainability efforts.
