Biodiversity

Constructing and managing a large real estate portfolio means we have an impact on the local climate and ecological environment of our neighborhoods. These are located primarily in major metropolitan areas, where the value of green spaces and trees is particularly high. This offers huge potential for sustainable action. We want to exploit this potential – not least to improve the quality of living for our tenants. Therefore, we maintain and design over 24 million square meters of green spaces, over 300 km of hedges and around 263,000 trees to create a sustainable and livable environment.

Promoting biodiversity in our residential developments is not just an ecological obligation, but also an opportunity to build a future worth living.

Our Objectives and Key Performance Indicators

Vonovia positions itself as a green residential real estate company, aiming to become the market and innovation leader in sustainable residential environment construction. What this means for us: 

  • We build and manage our residential environment in a resource-efficient, economical and safe way.  
  • We reduce and bind harmful greenhouse gas emissions.  
  • We protect and promote a diverse range of plant and animal species in our planted areas.  
  • We are already preparing for the potential consequences of climate change and are focusing on building resilience.  
  • We involve those who live our neighborhoods in the design of their living environment and want to raise their awareness of environmental issues and inspire them to live in an environmentally conscious way.  
  • We see ourselves as responsible not just for ensuring that our own portfolio is designed in a way that adds ecological value, but also for providing the impetus needed for environmentally conscious action.  

Target for 2024: Implementing and establishing our planning guidelines for sustainable open spaces and our design manual – developed in-house – in Vonovia’s construction planning and execution processes. 

Medium to long-term Target (2030-2045): Successively redesigning and upgrading our neighborhoods to transform them into resilient communities of plant species and habitats.

Challenges, Opportunities & Risks

Opportunities

By enhancing the ecological value of our properties and designing them to be resilient, we ensure a high quality of living and increase tenant satisfaction. Our large number of qualified professionals and the standardization of design modules and processes enable us to generate efficiency and cost advantages in planning and implementation. Through positive residential environment design, we also influence the development of neighborhoods and raise awareness among residents about the importance of climate protection.

Risks

Natural environmental conditions are noticeably changing: heat waves, rising temperatures, storms, and heavy rainfall are increasingly causing vegetation damage and infrastructure failures. Monoculture farming and soil sealing exacerbate this development. The result: biodiversity declines, as does the quality of life in the neighborhood. Additionally, pests like the oak processionary moth are becoming more prevalent.

Management Approach

We pursue a balanced approach that considers the individual requirements on-site while also relying on standardized processes with consistently high quality. Four aspects are particularly important to us:

  • Increasing biodiversity
  • Adapting to climate change
  • Engaging our tenants
  • Responsible use of resources

Our standardized solutions are documented in a design manual that includes a modular system for ecological neighborhood design. It provides the framework within which structural and design measures are implemented in the neighborhoods.

Before a measure is included in our modular system for ecological neighborhood design, it undergoes a qualitative development process, for example, involving experts from the Nature and Biodiversity Conservation Union (NABU). Together, we test various habitat types and nesting boxes for insects, bats, or endangered bird species (such as the common swift) in numerous projects. We also explore revitalizing habitats through blue-green infrastructure in water-retaining infiltration basins. In our pilot neighborhood in Bochum-Weitmar, after three years of collaborative development and testing, we have achieved the maximum number of habitats implementable for the housing industry. We will let this neighborhood develop for three to four years before conducting a new survey of flora and fauna.

Additionally, we consider the neighborhood criteria of the German Sustainable Building Council (DGNB) for biodiversity (ENV2.4) and water cycle systems (ENV2.2), whose standards we already meet in numerous neighborhoods.

ORGANIZATIONAL FOCUS

Responsibilities

Today, our portfolio includes over 24 million square metres of green space - around seven times the area of New York's Central Park - over 337 km of hedges and around 263,000 trees. The associated tasks are carried out by our Residential Environment Service and selected partner companies. Our Residential Neighbourhood Service, which concentrates on the German holdings, employs around 1,300 people. It carries out traditional open space maintenance and repairs and also realises larger gardening and landscaping projects.
