Vonovia SE ESG Factbook 2023

Foreword

Dear readers,

As one of Europe's leading private residential real estate companies with a portfolio comprising almost 550,000 apartments in around 65,000 buildings and a fair value of almost € 84 billion, we are aware of our particular responsibility towards our shareholders, tenants and society at large.

Vonovia provides homes and quality of life in almost all of Germany's attractive cities and regions as well as in Austria and Sweden. We take this responsibility seriously and actively seek to find answers to pressing social issues on the housing front. We are committed to greater climate protec- tion, create more senior-friendly apartments and foster community spirit in our neighborhoods. We also make a key contribution to building new apartments and our core business helps to support processes of social and ecological change.

Sustainability is thus a key component of our corporate strategy.

In order to provide transparent and comprehensive information on the progress we have made, and our performance, in the field of sustainability, we started publishing a separate annual Sustainability Report nine years ago.

Sustainability reporting has been subject to ongoing changes ever since. We are currently faced with more, and very far-reaching, changes as a result of the Corporate Sustain­ ability Reporting Directive (CSRD). The Directive means that the Annual Report is increasingly becoming the focal point of reporting, and will also provide considerably more quantitative information going forward.

Back in 2023, we revamped our website and, alongside our customer website (www.vonovia.de available in German only), also created a Group website (www.vonovia.com). The latter provides us with a whole host of opportunities for presenting information that we used to report in the Sustainability Report on the website in a corporate context.

This prompted us to take the next step with our sustain­ ability reporting and, instead of publishing a separate Sustainability Report, to present our sustainability strategy and all relevant sustainability topics on our Group website.

We also started enhancing our climate reporting by publish­­ ing our answers in the context of the Carbon Disclosure Project Assessment (CDP Climate Change). Our EPRA and PAI reports, which you will also find under the Investor Relations section of our website, create additional transparency.

A key component of our new reporting approach remains extensive figures that are audited by an independent third- party body. This ESG Factbook sees us continue with our tradition of detailed and audited ESG reporting.

The ESG Factbook supplements the Annual Report and the information provided on our website. All of the tables in the ESG Factbook are available to be downloaded as Excel files to make them more practical to use and analyze. We have kept the structure of the table formats more or less the same to ensure continuity and comparability, so a lot of the tables will be familiar to you if you have used our sustainability reports in the past.

We hope that this information goes some way to providing you with the knowledge you have been looking for. If you have any further questions, my team and I will be happy to help.

Reporting Framework

Principles/Material Topics

Vonovia conducts regular materiality analyses to identify and validate the sustainability topics that are relevant to the company. The current requirements set out by the Global Reporting Initiative (GRI) and, from the 2024 financial year, the European Sustainability Reporting Standards (ESRS) provide the framework for this. As a result, Vonovia has been applying the concept of double materiality for some time now and takes both the outside-in and the inside-out perspective into account when selecting the key sustainabil­ ity topics. The current materiality analysis can be consulted in the 2023 Annual Report. You can find further information on the materiality analysis on the Group website.

The materiality analysis applies to the entire Group. The main sustainability topics resulting from our materiality analysis can be clustered into five areas for action:

• Environment and climate
• Society and contribution to urban development
• Homes and customers
• Corporate culture and employees
• Sustainable governance and responsible business practices

We apply the structure of the three sustainability pillars - environment, social and governance (ESG), with the middle three areas for action being assigned to the social category. The ESG structure is also used in this ESG Factbook.

Reporting Framework

Vonovia's sustainability reporting in the Annual Report and in the ESG Factbook is based on the fiscal year and is pub­ lished annually. The reporting period for this ESG Factbook relates to the 2023 fiscal year (January 1 to December 31, 2023), meaning that it picks up exactly where the 2022 Sustainability Report, which was published in April 2023, left off.

As a capital market-oriented company, Vonovia SE is also required to make statements in accordance with Sections 315b, 315c in conjunction with Sections 289c to 289e HGB (Non-financial Group Declaration). These necessary reporting requirements were implemented in the management report of the 2023  Annual Report, which was published on March 15, 2024.

For the definition of selected key figures, we are guided by the Universal Standards (as amended in 2021) of the Global Reporting Initiative (GRI). In preparation for the CSRD implementation that will be relevant for the 2024 fiscal year, we are already using some of the ESRS key indicator definitions in this ESG Factbook. Insofar as key figures are disclosed in orientation to GRI or ESRS, we refer to the corresponding standard in the table header.

Organizational Boundaries/Scope of Consolidation

The key figures presented in the ESG Factbook reflect Vonovia SE's activities in Germany, Austria (BUWOG AT) and Sweden (Victoriahem AB) and are based on the financial control approach. They include those companies presented in the list of shareholdings in the 2023 Annual Report that are also included in the consolidated financial statements. Entities with minority interests and apartments owned by third parties are not included.

Deutsche Wohnen SE, which has been part of the Vonovia Group since September 30, 2021, is fully integrated in the consolidated reporting. This excludes the Deutsche Wohnen SE subsidiaries allocated to the Care segment. This area has been classified by Vonovia SE as discontinued operations and consists of the care business and care properties. As of December 31, 2023, we employed a total of 3,825 people in care service or care home management. Care business operations are based on an independent system and process landscape, and 39 retirement and care homes are operated under the brands KATHARINENHOF and PFLEGEN & WOHNEN HAMBURG, 38 of which are owned by Deutsche Wohnen. There are also an additional 33 nursing care properties run by other agencies.

Vonovia SE ESG Factbook 2023

Due to the integration process that was implemented in 2022, many of the key figures reported for the 2022 fiscal year already include Deutsche Wohnen SE. We provide information on the status of the figures in the footnotes. The information presented for the 2021 fiscal year excludes Deutsche Wohnen. The definition of the scope of the ESG Factbook in terms of the consolidated companies is regularly reviewed and adjusted if necessary.

Coverage

Residential property is the primary asset class in Vonovia SE's real estate portfolio, accounting for 98.4%. With almost 65,000 buildings in the portfolio, reporting is aggregated at portfolio level.

Data aggregation is performed at the level of individual countries and the information is consolidated at this level and at overall Group level. The key reporting figures make a distinction between the core markets of Germany, Austria and Sweden.

The breakdown can be made at country level according to the rentable area or the number of employees (headcount):

	Region		Rental space	Headcount
	Coverage
	Germany	86.5%	92.3%
	Austria	4.8%	3.1%
	Sweden	8.6%	4.6%

For a detailed segment analysis of the portfolio, please refer to the section entitled Portfolio Structure in the 2023 Annual Report.

Any deviations from the degree of coverage are explained directly in the corresponding tables of key figures.

Underlying Data/Estimation Techniques

Due in particular to the decision to start switching individual key figures over to the upcoming European ESRS reporting format early on, it was once again the case in the reporting year that some key figures were adjusted in methodological terms, or changes were made to their presentation. This relates primarily to the structure of the greenhouse gas and energy consumption tables, the amount of waste in the portfolio and the occupational safety and gender pay gap tables. We explain the changes in the relevant table of key figures.

As far as possible and to the extent that the data is available at the required time, we use values that have actually been measured for our data analyses. Where data availability is restricted, we use generally recognized estimation techni- ques, for  example in the area of tenant-related utility services, which are invoiced directly to tenants.

Energy certificate data forms the basis for calculating the portfolio's energy consumption and greenhouse gas emissions.

Third Party Assurance

Like the Non-financial Group Declaration in the Annual Report, the ESG Factbook was subjected to a separate limited assurance audit conducted by PwC GmbH Wirtschafts- prüfungsgesellschaft, Essen, in accordance with ISAE 3000. The Supervisory Board passed a corresponding resolution at its meeting on March 16, 2023 (see Supervisory Board Report). All references to content outside this ESG Factbook are considered additional information and are not covered by the business audit.

Key Figures

In the sections below, you will find selected key sustain­ ability figures for our company. We have structured this information­ based on the three sustainability pillars:

E(nvironment), S(ocial) and G(overnance). The table

­structure is based on the pattern that, for each of the past

three fiscal years (2021, 2022 and 2023), we report on a consolidated basis for the Group as a whole, also making distinctions at country level (Germany, Austria and Sweden) for the current 2023 reporting year.

Notes on the Greenhouse Gas Emissions

This greenhouse gas balance (GHG balance) was prepared on the basis of the standards of the Greenhouse Gas Protocol (GHG Protocol Corporate Standard and Corporate Value Chain (Scope 3) Standard, the internationally recognized standards for calculating greenhouse gas emissions. The recommendations set out in the guidance issued by the Federal Association of German Housing and Real Estate Enterprise Registered Associations (GdW), "Arbeitshilfe 85 (CO2 Monitoring)", and the recommendations published by the Wohnen 2050 housing initiative (IW2050), have also been taken into account. The scope of consolidation relevant to Vonovia's greenhouse gas balance matches that of the other environmental indicators in this ESG Factbook. GHG emissions were calculated in carbon dioxide equivalents (CO2e), the standardized unit to measure the relative contributions to the greenhouse effect of the greenhouse gases CO₂, CH₄, N₂O, SF₆, HFCs and PFCs regulated by the Kyoto Protocol.

The calculation of GHG emissions in the portfolio is conducted according to the financial control approach. Emissions produced as a result of portfolio operations over which Vonovia has full control are disclosed under Scope 1 and Scope 2 emissions. For the part of the portfolio, in which the company holds a minority interest, the carbon emission figures are reported under Scope 3.

As actual measured values for the relevant reporting year are not available at the required time, we calculate the emissions on the basis of the valid energy certificates of the individual buildings. The energy consumption of those buildings that do not have energy certificates is extrapolated based on the age of the building and corresponding average values based on the rest of the portfolio.

To calculate the emissions from the combustion of fossil fuels and location-based emissions in Scopes 1, 2 and 3.3, the CO₂e factors from version 5.1 of the GEMIS (Global Emission Model for Integrated Systems) database were used. GEMIS is an internationally recognized model for determining energy and material flows with an integrated database. The model calculates life cycles for all processes and scenarios, i.e., it takes into consideration all material steps from pri­ mary energy and raw material extraction to effective energy and material provision, and also includes the auxiliary energy and cost of materials to produce energy plants and transport systems.

In order to calculate market-based emissions, the specific emission factors of the energy suppliers were used where this data was available. With regard to the purchase of district heating from combined heat and power (CHP) plants, we use emission factors based on the Carnot allocation method, as this allows for more realistic allocation of

emissions to heat or electricity in physical terms. If no specific emission factors were available, the corresponding location-based factor was used. If other emission factors are applied in individual cases, this is indicated accordingly.

Explanatory information on the scopes included in the GHG balance:

Scope 1 - Direct emissions: GHG emissions from stationary combustion for heating and warm water, as well as mobile combustion (vehicles owned by the company).

Scope 2 - Indirect emissions from energy purchases: GHG emissions from the generation of (general) electricity, local and district heating for heating and warm water. When calculating the GHG emissions, we have changed the emission factor for district heating from combined heat and power (CHP) plants from the energy-based allocation method to the Carnot allocation method with effect from the Sustainability Report 2022. Accordingly, the values for 2021 are not directly comparable with those of the subsequent years.

Scope 3 - Indirect emissions in the upstream and down­ stream value chain (where these are identified as material and can be calculated):

• Scope 3.2 Capital goods: GHG emissions from the produc- tion of building and other materials used for the new buildings completed in the fiscal year in question. The GHG emissions are calculated using emission factors based on the building construction method as prepared by external experts as part of a comprehensive life cycle assessment for a model home. In previous years, these emissions were reported as Scope 3.1 emissions. Starting in the 2023 fiscal year, we adjusted this in accordance with the GHG Protocol and switched to reporting them as Scope 3.2 emissions.
• Scope 3.3 Fuel and energy-related emissions (not Scope 1+2): GHG emissions from the upstream chain of energy sources not reported as Scope 1 or Scope 2 emissions (e.g., for the extraction and transportation of fuels or the pro- duction and transportation of electricity and district heating) - both for the wholly owned real estate portfolio and for apartments managed on behalf of third parties (their Scope 1 and 2 emissions are reported as Scope 3.13 emissions).
• Scope 3.6 Business travel: GHG emissions from business trips billed to the company. To calculate Scope 3 emissions from business rail travel, we used emission factors taken from Deutsche Bahn and Österreichische Bundesbahnen. Business travel and transport were also reported for

Vonovia SE ESG Factbook 2023

Sweden for the first time in 2021. The emission factors from external travel agencies were applied for flights.

• Scope 3.13 Downstream leased assets: GHG emissions generated from household electricity used by tenants in their homes for electrical appliances (excluding general electricity or electricity required for heat and warm water). The corresponding electricity consumption is estimated based on a method developed at sector level, since real data is not available to the landlord. The national emission factor for electricity is used to calculate emissions (location-­based). In addition, GHG emissions result from the supply of heating and warm water to rental units that belong to a residential property owners' association (WEG).

Vonovia will expand its GHG balance on an ongoing basis to include further material Scope 3 categories and include them in its reporting in the future.
