With Swisscom's environmental products we aim to reduce human impact on the environment. How is this done? We are improving the efficiency or ecological impact of our products by optimising their complete lifecycle. The grey energy of a mobile phone is, for example, 60% of the total energy involved. To become more ecological, we must either save energy in production techniques or increase the product's lifetime. Swisscom is already on the road to success: In the Solidarcomm project we give old mobile phones a new lease of life. We offer our customers energy-efficient Ecomode plus cordless phones.
