Commitment to achieving net zero

Sonova UK, Sonova Service Centre UK Ltd and Advanced Bionics UK Ltd is committed to achieving net zero emissions by 2050

Baseline emissions footprint

Baseline emissions are a record of the greenhouse gases that have been produced in the past and were produced prior to the introduction of any strategies to reduce emissions.

Baseline emissions are the reference point against which emissions reduction can be measured.

Baseline year: 2019
Additional details relating to the baseline emissions calculations:

Sonova UK, Sonova Service Centre UK Ltd and Advanced Bionics UK Ltd are all subsidiaries of Sonova Group. While Sonova UK Ltd and Advanced Bionics UK Ltd mainly carry out marketing, sales activities and distribution, Sonova Service Centre UK Ltd carries our repair and manufacture of hearing instruments. Combined, these subsidiaries employ 245 FTEs (per 24th June 2025). The GHG emissions of these three subsidiaries are reported together under the carbon reduction plan.

Sonova Group's GHG emissions have undergone limited assurance in accordance with ISAE 3000 (revised) and ISAE 3410 both in the base year 2019 as well as the current year 2025.

Carbon reduction projects

Completed carbon reduction initiatives

The following environmental management measures and projects have been completed. The carbon emission reduction achieved by these schemes equate to 1137 tCO2e, a 71% reduction against the 2019 baseline and the measures will be in effect when performing the contract:

For SUK+SSC initiatives:

• Open Plan temperature A/C - lockup system set up at 21°C.

• Screens and Desktop on power saving mode.

• Reduced heat lost by isolating heat pumps in the Loading area.

• Removal of portable heaters and fans.

• The chiller pipes - damaged insulation repair.

• Reduced temperature after 'core hours'.

• Reduced temperature on Weekends.

• Removed halogen lights and replaced them with LED lights.

• Started sourcing 100% renewable electricity for all sites in Scope

• Moved towards a lower carbon car fleet by switching to hybrid and electric vehicles.

• Reduced the amounts of operational waste.

• Implemented a hybrid working guideline for office-based employees, who can work, up to two or three days remotely. Thus, reducing employee commuting related GHG emissions.

For AB UK initiatives:

• Office fully upgraded new air conditioning units.

• Removal of portable heaters and fans.

Future carbon reduction initiatives

In the future we hope to implement further measures such as:

• All the car fleet to change to electric.

• Review air-travel policy to ensure more responsible business travel.
