Using resources efficiently

As Switzerland's tenth largest power consumer, we are conscious of our special responsibility. This is why we do our utmost to make more efficient use of our resources through innovation, so that future generations will be able to enjoy the same chances and opportunities as we do today.

Swiss Government Energy Strategy 2050

Our role as a model energy consumer

As part of the Swiss government's Energy Strategy 2050 we have been chosen as a role model alongside the Post Office, SBB, Skyguide, ETH, the Swiss Federal Administration and institutions with strong links to government. The aim is a 25% increase in energy efficiency between 2006 and 2020. We achieved this target with 34% at the end of 2015 and aim for a further 35% between 2015 and 2020.

Solar Impulse

Around the world with solar power

We believe in the future of renewable energy. This is why we support the Solar Impulse project as official partner. In the Solar Impulse 2 Bertrand Picard and André Borschberg are flying around the world in a plane that, for the first time ever, is driven entirely by solar power. On board: our communication solution.

100% renewable energy

Solar, wind and water power

We draw our electricity (2015: 434 GWh) exclusively from renewable domestic energy sources. As one of Switzerland’s biggest consumers of wind and solar power, we purchased a total of 18.5 GWh of naturemade star-certified eco-electricity from Switzerland in 2015. Naturemade star is regarded as Switzerland's strictest eco-electricity label. We also generate up to 1 GWh annually with our own solar plants and thus cover the electricity needs of all Swisscom standard workplaces.

Fresh-air cooling

Telephone exchanges must be cooled non-stop. With our Mistral project, we have developed a unique, environmentally friendly ventilation system that cools telecommunications equipment with fresh outside air and discharges warm air outside. Each year, this saves us the energy equivalent of 9,000 households (45 million kilowatt hours). An important side-effect is that environmentally harmful refrigerants are no longer needed. Mistral is a key element of our efforts to increase energy efficiency.


Intelligent energy-saving

We are committed to ensuring that the devices we sell use as little energy as possible in their manufacture and operation, particularly in stand-by mode. Our new TV-Box, for instance, uses 40% less energy than its predecessor. With our new tiko solution, we also help customers optimise their heating consumption. At the same time, tiko enables electric power stations to stabilise the electricity grid when fluctuations in wind and solar power generation occur due to weather conditions.

Energy-efficient operation

Advanced ecological standards

We comply with the latest ecological standards in our business premises and data centres. Our business parks in Köniz or Ittigen are thus certified to the Minenergie performance standard. We also use state-of-the-art cooling systems in our data centres, and in our newest centre we achieve 60 per cent higher energy efficiency than is customary by international standards.
