Acting with environmental awareness must be based on knowledge. With this concept in mind, we launched an internal environmental campaign in 2008 and this was continued in 2009. It communicates concrete knowledge to our employees and gives them hints on how they can make a contribution to environmental protection. One example where they can make a difference is saving energy. That means switching off notebooks and monitors at night and unplugging chargers as soon as batteries have been recharged. We communicate this kind of information by affixing stickers as well as by providing information on the Intranet.

We published an environmental brochure for our customers in 2009. It provides information on how to save energy when you're using telecommunications equipment and computers. It also includes information on recycling mobile phones, and this was included in communication with business customers. We presented our measures in our newsletter entitled "essential" and our "Elements" magazine.

In 2009, we joined forces with the World Wide Fund for Nature (WWF) to launch another campaign based on several years of cooperation. The July issue of the WWF magazine provides readers with a stamped, addressed envelope which allows them to send their mobile phone for managed recycling through our "Dr. handy" recycling partner.

We now offer our customers a series of packages that enable them to conserve resources. This issue is covered in product communication as well as being the subject of strategic campaigns. The products exerting a positive effect on the environment include a platform for web conferences that we offer together with our partner Meetyou. Up to 250 people can participation in a web conference. This tool is one way of reducing business trips.

Since 2008, our customers have been able to retain their mobile phone when they change tariffs. They only need to change the SIM card. The advantage of these SIM Only contracts is that the basic charge comes down. Overall, this option also protects the environment because is allows existing mobile phones to continue in use. We intensified our campaign for SIM Only phones in 2009. Many of our customers have taken up this option.

We used 700 tonnes of paper in 2009 to print out invoices. We offer online registered private customers and new private customers the option of receiving electronic documents as an alternative when they take out a contract. At the end of 2009, more than half of them had decided to opt for this environmentally friendly option. We want to achieve a proportion of 55 percent for online invoices in the coming year.
