Geberit Group – Greenhouse gas balance (Scope 1 and 2) for the financial year 2023
> Independent auditor’s report

Audit result

Based on our audit, nothing has come to our attention that causes us to believe that the Geberit Group’s Scope 1 and 2 greenhouse gas balance for the financial year 2023 has not been prepared, in all material respects, in accordance with the criteria. Based on this assessment with limited assurance, we can therefore confirm that the subject matter complies with and meets the specified criteria.

Mandate and scope of the audit

We have been engaged to perform a limited assurance review for the reporting period from 1 January 2023 to 31 December 2023 on the following subject matter:

• The Geberit Group’s greenhouse gas balance (Scope 1 and 2) for the 2023 financial year
• The workflow for data collection, calculations and aggregation as well as the verification process as part of the greenhouse gas accounting for selected production sites
• The process for obtaining guarantees of origin (GoOs) for the purchased electricity

Assessment criteria

The greenhouse gas balance was prepared based on the following criteria defined by Geberit:

• ISO 14064-1:2018, WRI/WBCSD Greenhouse Gas Protocol and GRI Standards 302-1, 305-1, 305-2 and 2-5
• The GHG reporting processes defined by Geberit and listed in the EHS Managers’ Manual, as well as the specified templates for data collection and data validation by the EHS Managers at site and Group level

Responsibility of Geberit AG

The Executive Management of Geberit AG is responsible for the preparation of the greenhouse gas balance in accordance with the criteria. This responsibility includes the design, the implementation and maintenance of adequate internal controls related to the preparation of the greenhouse gas inventories, including the calculation of greenhouse gas emissions, that are free from material misstatement, whether due to fraud or error. In addition, the management is responsible for the selection and application of criteria and for maintaining appropriate records.

Responsibility of the auditor

Our responsibility is to express an opinion on the greenhouse gas balancing and the emission factors used therein based on our limited assurance engagement.

We conducted our review in accordance with the Guidance for the Verification and Validation of Greenhouse Gas Statements (ISO 14064-3:2019) to determine whether the subject matter has been prepared, in all material respects, in accordance with the criteria listed above.

Considering risk and materiality considerations, we performed audit procedures to obtain sufficient and appropriate audit evidence. The procedures selected depend on the judgement of the independent auditor. In a limited assurance engagement, the procedures performed are less extensive than in a reasonable assurance engagement and therefore offers a more limited level of assurance.

We have performed the following essential work:

• Assessment of the requirements for greenhouse gas balancing and their practical implementation
• Interviews with key data suppliers and EHS managers from selected locations: Wesel (DE), Lichtenstein (DE), Bromölla (SE), Ozorków (PL)
• Interviewing the managers at group level in the areas of procurement and sustainability
• Inspection of the organisational structure, the level of knowledge and training of the employees involved, the methods of data collection and processing as well as the internal controls that are relevant for the audit review
• Analytical considerations, interviews and inspection of the documentation of the systems and processes for collecting, calculating, recording, analysing and aggregating the data, including document reviews and random sampling
• Assessment and review of the methodology used to calculate the Geberit Group’s greenhouse gas balance (Scope 1 and 2), including the process for obtaining guarantees of origin (GoOs) for the purchased electricity

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit result.
