The Chill Hunters

The Chill Hunters

By BBC Radio 4

There's a dirty secret around the back of your fridge. The world's freezers, fridges and air conditioning units are chilled by gases that have planet-warming properties that are hundreds or even thousands of times more powerful than carbon dioxide. Disposed of properly they're not a problem but in much of the developing world these gases- legal ones and even more dangerous illegal gases- are simply vented to the atmosphere when the cooling units are dumped or recycled.

In the first of ten more programmes highlighting the world's best carbon-busting ideas, Tom Heap meets the fridge detectives hunting the planet for the worst offenders and safely disposing of their dangerous gases.

Dr Tamsin Edwards of King's College, London, armed with statistics gathered by the Royal Geographical Society, joins Tom to add up the numbers and calculate the carbon impact of the fridge detectives.
