Application of ESRS disclosure requirements

The reference table and list of data points resulting from other EU legislation are included in the appendix ‘Additional information’. (ESRS 2 IRO-2 par. 54 en 56)

For each disclosure requirement, consideration has been given to the information relevant to the topic and the related material impacts, risks, or opportunities. At the same time, the information needs of the most important stakeholders (including silent stakeholders) have been taken into account to ensure they have a clear understanding of Enexis’ impact and, if necessary, can incorporate this information into their decision-making. Departments within Enexis that are in (daily) contact with stakeholders provided input. This included reviewing external reports from recent years and providing feedback. No direct input from stakeholders was sought. (ESRS 2 IRO-2 par. 59)

The minimum reporting requirements (MDR) for policies (MDR-P), actions and resources (MDR-A), metrics (MDR-M), and targets (MDR-T) are detailed for the material sustainability topics in the relevant chapters of the Sustainability Statement. They are specifically mentioned in the ‘Reference table’ in the appendix.

Unless explicitly stated otherwise, the results included in the Sustainability Statement have not been validated by any external body other than the assurance provider.

Integration of sustainability performance into remuneration policies

The General Meeting of Shareholders approved the remuneration policy for the EB of Enexis Holding B.V. on 5 December 2012 and came into effect on 1 January 2013. Under this policy, it was decided that the EB’s remuneration would be determined per the Standards for Remuneration Act (Wet Normering Topinkomens, WNT). Neither the remuneration of the EB nor that of the SB for the financial year 2025 is linked to performance on the sustainability topics included in this Sustainability Statement. Enexis does not offer variable remuneration. (ESRS 2 GOV-3 par. 27)

Value chain estimation

The following metrics, which contain data on the upstream and/or downstream value chain, have been estimated based on indirect sources: (ESRS 2 BP-2 par. 6 en 10)

Metrics

Basis for preparation

Planned actions to improve the accuracy

CO2-eq of scope 3 GHG-emissions (ESRS E1) categories insofar as data is not obtained directly from suppliers or raw material passports

Spend based data; extrapolation; various generic emission factors

Direct acquisition of supplier data instead of spend-based where possible; aim for less extrapolation

CO2-eq emission due to refrigerant leaks of air conditioners

Assumption that each air conditioner has an average of 3% leakage on an annual basis

Sources of estimation and outcome uncertainty

The following quantitative metrics and monetary amounts have high measurement uncertainty: (ESRS 2 BP-2 par. 6 en 11)

Sources of metric uncertainty

Assumptions, approximations and judgments used

Gas leakages

Gas leakages are calculated based on specific information, such as excavation damages and pipeline length in kilometres. To determine the emissions per damage and leakage, assumptions and estimates are made.

Technical gas leakage is calculated on the basis of the OGMP. An external party (KIWA) determines the assumptions used in the calculation method, which Enexis adopts.
Administrative gas leakage is calculated by subtracting the technical leakage from the total loss. The remainder is the administrative gas leakage

CO2-eq reduction measures (ESRS E1)

The effects of the measures are partly based on assumptions and extrapolation of measures already implemented.

It is assumed that the scarce capacity of contractors required to implement the reduction measures will be sufficiently available.

Euro's (CapEx en OpEx) for the benefit of CO2-eq reduction measures (ESRS E1)

The costs of the measures are partly based on assumptions and extrapolation of measures already implemented

Standard prices have been used when calculating the costs of certain work (e.g. replacement of gas pipes).

CO2-eq emissions of components in scope 3 category 2 (ESRS E1) and inflow of primary raw materials per unit of product (ESRS E5)

Material passports are used for the calculation of the CO2-eq emissions of components as part of scope 3 category 2 and for the calculation of the primary and secondary raw materials per unit of product in the Circularity chapter.

The degree of circularity and the CO2-eq emissions of components are estimated on the basis of material passports provided by suppliers. One material passport is used per article number, even when multiple suppliers with different material passports supply the same article.

Changes in preparation or presentation

Compared with the reporting on metrics in previous annual reports, the following information has been prepared or presented differently: (ESRS 2 BP-2 par. 6 en 13)

Modification and reasoning

Adjusted comparative figure(s)

Difference compared to figure reported in previous period

Modification CO2 footprint 2024. Explanation is included in E1 "Our greenhouse gas emissions".

Scope 1: modification emission factors gas consumption buildings and methane.

113,635 ton CO2-eq

8,061 ton CO2-eq

Scope 2: CO2-emission factor grid loss electricity transmission location based adjusted.

336,967 ton CO2-eq

-115,326 ton CO2-eq

Scope 3: Several adjustments.

549,039 ton CO2-eq

-66,405 ton CO2-eq

Modification Energy consumption and mix 2024. Explanation is included in E1 "Energy consumption and mix".

Classification of gas consumption buildings has been adjusted from 'renewable' to 'fossil sources' and therefore been recalculated using the correct conversion factor.

6,073 MWh gas consumption fossil sources
6,548 MWh gas consumption renewable sources

1,551 Mwh

Modification in data resource use and circular economy 2024. Explanation is included in E5 'Inflow of resources' within the respective tables

Table primary material per unit of product: Percentage progress in reducing primary material in MV cables has been adjusted

3,60 kg primary material per unit / increase of 9% opposed to 2014

+0,12 kg primary material per unit / increase of 4% opposed to 2014

Table material in kilograms: kilograms and distribution of primary/secondary material

24,662,371 kg

-1,251,980 kg

1To ensure the comparability of the 2025 CO₂ data with that of 2024, these factors have been applied retroactively to 2024, even though they only became available in 2025
