大家都对食物的碳排放量有所耳闻，但听说超市里冷却食物的空调的碳排放量吗？在流行低碳的今天，英国超市因使用含氢氟碳化物（HFC）的空调碳排放量居高不下，成为众矢之的。
The Environmental Investigation Agency or EIA has been analyzing the impact of supermarket cooling on global warming for the past two years. They have found that a strong, manmade greenhouse gas is being used as standard in UK supermarket refrigeration.
The EIA says the leakage of hydro fluorocarbon gases, or HFCs, accounts for a third of the UK supermarket carbon footprint, the equivalent to the production of five billion plastic carrier bags.
Hydro fluorocarbons were the gases brought in to replace CFCs - the ozone-destroying gases of the 1990s. Campaign manager at the EIA,
