• Climate-neutral subscriptions require a climate-neutral network (mobile and fixed-telephone network) and climate-neutral devices (Internet boxes, TV boxes, WLAN boxes and smartphones).
• The Swisscom network is climate-neutral: Swisscom has been operating its entire network with 100% renewable energy for over 10 years and generates some of the electricity it consumes itself thanks to its 87 photovoltaic plants. By continuously modernising the technology and increasing energy efficiency, we have also been able to reduce CO2 emissions from operations by over 80% since 1990. All these measures result in fewer CO2 emissions. We offset all residual CO2 emissions that we cannot reduce ourselves.
• Devices are climate-neutral: Swisscom’s own products such as Internet and TV boxes have been climate-neutral since 2020. This is due to more efficient production and optimised packaging. We do not produce smartphones ourselves, but we fully offset the CO2 emissions generated during production, transport and use on behalf of our customers. Offsetting means that CO2 emissions are prevented or removed from the atmosphere by investing in climate protection projects to reduce an equivalent quantity of emissions elsewhere. Swisscom supports various recognised climate protection projects.
