A new mobile phone charger that will work with any handset has been approved by the International Telecommunication Union (ITU), a United Nations body.

Industry body the GSMA predicts that 51,000 tonnes of redundant chargers are generated each year.

Currently most chargers are product or brand specific, so people tend to change them when they upgrade to a new phone.

However, the new energy-efficient chargers can be kept for much longer.

The GSMA also estimates that they will reduce annual greenhouse gas emissions by 13.6m tonnes.

About time too. Now for digital camera chargers…

Thanks to James Miller for spotting it.
