Ken Livingstone today launched the first 'London Light Bulb Amnesty' with Londoners being encouraged to trade in their old style power hungry light bulbs for low energy, long life alternatives.
The scheme, taking place between Friday 11 January and Sunday 13 January, is being run by British Gas - who will supply the new bulbs - and DIY retail giant B&Q, who will oversee the exchanges across their 28 London stores.
"Small lifestyle changes like this really do add up,” claimed the London Mayor. “If all homes in the capital used energy efficient bulbs, we could collectively help reduce emissions by over half a million tonnes, and save £139 million every year."
If you can’t make it down to this weekend’s amnesty, or you have more bulbs to change than the limit of two per household will allow, it's also worth noting that Tesco, in conjunction with consumer climate change campaign We’re in This Together, is now permanently knocking out low energy bulbs at half price and is currently running a three-for-the-price-of-two promotion.
