Tony Blair has given his backing to a new campaign aimed at saving the planet from environmental catastrophe.

The Global Cool campaigners who came to Number 10 want to get one billion people to each reduce their carbon emissions by one tonne a year.

Among those at the reception to launch the 10-year campaign were Stephen Fry, KT Tunstall, Josh Hartnett, Brian May and Anita Dobson.

Also in attendance was rock star Perry Farrell, who presented the PM with a CD of his new band Satellite Party’s track, Woman in the Window.(via: 10 Downing Street – Click Here for their Podcast of the event)
