Energy use and climate protection

Given the serious impacts of climate change that we are already seeing, it is crucial that Sunrise should follow a clear direction with specific goals and measures. As part of the Science-Based Targets initiative (SBTi), Sunrise is committed to a science-based and gradual reduction of greenhouse-gas emissions. This reduction, based on the SBTi, is in line with the goals of the 2015 Paris Climate Agreement and emphasises the long-term commitment that Sunrise has made.

The Sunrise headquarters at Ambassador House are noted for their environmentally friendly, efficient and sustainable construction, as demonstrated by the fact that the building has achieved the highest possible LEED Platinum certification level. Sunrise powers its own offices in an energy-efficient way using renewable energy, where possible, for example from community heating, LEDs, sensor-controlled lights, etc.

To help Sunrise move closer to its emissions-reduction targets, it already uses only 100% renewable electricity and is also committed to ensuring its own fleet of vehicles runs solely on electric power by 2030. Through to 2030, the energy efficiency of data transmission (kWh/TB) in the network will be improved continuously by replacing older components with newer technologies. Artificial intelligence (AI) makes better use of existing network capacities. Embracing the innovative PowerStar solution in 2022 meant that the Sunrise mobile network’s power consumption fell by 6.4 million kWh – enough power to supply a Swiss village of around 2,700 inhabitants – without affecting customer experience or network performance at all.
