Kimberley Walsh, Ashley Banjo, and Perri Kiely are among the celebrities supporting The BT Big Sofa Summit campaign, 'encouraging people across the UK to get talking about climate change'.

The campaign focuses on teaching the nation about how smart technology can help the environment within their own homes, and provides free advice and resources on the small steps that everybody can take to reduce household emissions. The former Girls Aloud star held her own summit discussing how to be greener at home, and commented 'Every time you turn on the news, there’s always a story about the doom and gloom of climate change so it can be very easy to get overwhelmed by it all. That’s why it’s great BT has given us an easy way to start talking about the problem and is showing us how helpful tech can be for the environment. The BT Big Sofa Summit is a simple, positive way of figuring out the small steps you can take as a family to make your home greener'.
