Sienna Miller has been showing her support for a global warming campaign by sporting a trendy new Glocal Cool t-shirt and Female First have 5 of the campaign's t-shirts which have been signed by Sienna herself to give away.

Sienna is among a long list of celebrities supporting the Global Cool campaign and wore their specially designed tshirt for a recent campaign trip to Mumbai.

In the style of the popular 80s slogan tshirts the top reads "The People Versus Global Warming". The design has become the latest fashion must have and is now available for the public to buy.

Kate Bosworth and Rosario Dawson have also been seen wearing the same tshirt and Josh Hartnet and Heather Graham are also supporting the campaign which aims to get a billion people to donate a 'Tonne of Cool'by using online tips to reduce their Co2 emissions by a tonne in a year.

Global Cool t-shirts are also eco-friendly made from 70% organic bamboo and 30% organic cotton which is then shipped to the UK. The fabric woven from bamboo yarn is light, almost translucent, and softer than cotton. It has a natural quality that feels like silk, but has the advantage of being machine-washable

Global Cool’s aim is to get a billion people to donate a Tonne of Cool by registering with www.globalcool.org/myco2. A Tonne of Cool is a clever cocktail of environmental goodness that invests in energy reduction projects and new green technology, all while sparing the world at least one tonne of CO2. To enter just answer the following question:
