Swisscom is striving to boost energy efficiency and rely more on renewable energies in order to minimise the environmental impact of its business activities. In Switzerland, Swisscom has set itself the goal of increasing its energy efficiency by a further 35% by the end of 2020 compared with 1 January 2016. The increase will be achieved primarily by measures in the network infrastructure area. Together with its customers, Swisscom is also aiming to save twice as much CO2 as it emits throughout the entire company including the supply chain by 2020. Swisscom intends to achieve this target on the one hand by reducing emissions, and on the other by promoting and marketing a sustainable product portfolio.

In 2016, total energy consumption in Switzerland rose by 15 GWh or 2.9% to 536 GWh. The efficiency measures introduced to improve cooling in telephone exchanges and cut energy consumption in data centres partly offset the additional energy consumption attributable to network expansion. Swisscom achieved an average PUE (power usage effectiveness) value of 1.47 across all of its data centres in 2016 (prior year: 1.50). In 2016, as in previous years, Swisscom once again used 100% renewable energy. Energy efficiency improved versus 1 January 2010 to 35.9% (prior year: 29.6%), and versus 1 January 2016 by 8.9%. In 2016, direct CO2 emissions in Switzerland decreased by 279 tonnes or 1.4% to 19,837, chiefly due to lower consumption of fossil fuels. The ratio of savings among customers to emissions climbed from 0.81 to 0.99 in 2016.
