This is the cell C eco diary. It features a solar charger on the cover that can charge almost any cell phone. It includes 312 poems on being green, and provides tips and guides on living a greener lifestyle. It was mailed to existing subscribers and staff.The idea behind the execution was to teach customers that when you make a few simple changes, like using a solar panel to charge your cell phone, you can make a huge difference to the environment. Plus, who better than a Cellular company to send you a solar charger to charge your phone?

Emails from staff and customers came flooding in thanking Cell C. The diary also appeared on blogs, like africancarbontrust.org, and it achieved second place in the South Exhibition, an initiative that honours South Africans for ideas that focus on sustainability. It also featured on the national television program, Morning Live. Due to this positive response the diary is being developed for the retail market and should be released to the market by 2010.
