Londoners are being urged to begin the year in a green manner by recycling their Christmas trees and other rubbish from the festive period.
The tree in Trafalgar Square was shredded and will be composted
The Recycle for London campaign was launched with the shredding of the 22m Christmas tree at Trafalgar Square.
London Assembly member Murad Qureshi fed the tree to a chipping machine.
An estimated 976,000 Christmas trees and 124m cards will be thrown away in London instead of being recycled, the campaign said.
To make recycling easy 26 boroughs are offering to collect the trees and other festive rubbish from home, while the remaining 17 councils have set up drop-off points for Christmas trees.
Urging the city to take some green resolutions, London mayor Ken Livingstone said: "Currently Londoners recycle less than a quarter of their rubbish."
Londoners produce 3.4 million tonnes of waste a year, and this increases by 10% during the festive period, including glass jars, bottles and wrapping paper.
Mr Qureshi said: "I hope today's recycling of the Trafalgar Square Christmas tree will encourage Londoners to make a greener start to 2008."
