A recent survey of British supermarket chains revealed refrigerators and freezers contribute 25% of a stores’ carbon-footprint.
Environmental groups say supermarket refrigeration units spew hydrochlorofluorocarbons, greenhouse gases that can be 4,000 times more harmful than carbon dioxide. Eek!
The survey ranked popular supermarket chains from 1 to 10. Marks & Spencer and Tesco placed the highest, with Tesco upping its rank by investing in climate-friendly refrigeration, but retailer Iceland ranked last, getting a negative rating; The Herald reports.
Oddly, all of the stores refused to provide information about they are doing to improve operations.
Now, it might not be a supermarket, but restaurant Chipotle greened up their business by installing a wind turbine on restaurants, LEED lighting and more!
