Sustainability at Instone

It is our self-image to take a leading role in the development of an ecologically sustainable economy with social responsibility and good corporate governance.


Sustainability vision

We are committed to fulfilling our social responsibility: the environment, society and economy are the foundation of our business activities. 

They all carry equal weight and are taken into account in everything we do.

As a company, we aim to achieve lasting business success while at the same time taking responsibility for people and the environment.

"We clearly assume a social responsibility with our projects and our general entrepreneurial activities.

For the future, we have set ourselves a significant reduction in CO2 emissions as a key strategic goal in the area of sustainability. In the future, we want to successively analyze our ecological footprint, already starting from a good base, and improve it even further. "

Dr. Foruhar Madjlessi, CFO


Guiding principles for our business policies and activities


Instone Real Estate is committed to fulfilling its environmental, social and economic responsibility. This commitment forms the foundation of our business activities.



Our customers are our main focus. We deliver them sustainable products and reliable quality.


Environmental and climate protection and resource usage are factors evaluated and taken into account in all project developments and carefully considered in relation to climate action goals.


Instone Real Estate strives to grow based on a strategy oriented towards long-term business success.


Our employees are our Company’s main asset. The cornerstones of Instone’s corporate culture are trust and respect as well as working together to achieve the goals we have set.


Our aspiration is to develop projects precisely tailored to meet the needs of our customers with environmentally, socially and economically sustainable qualities.


We generate ideas and leading-edge processes to benefit sustainable corporate development through our collaboration with associations, start-ups, organisations, municipalities and other groups in society.

Sustainability management

The Management Board member responsible for sustainability is our CFO, Dr Foruhar Madjlessi. 

In the Sustainability Steering Committee, the board of directors and a representative of the management as well as the sustainability officer and two representatives of the coordinating sustainability team come together to bundle, discuss and initiate measures on all relevant strategic and operational issues. The sustainability officer coordinates the issues relating to the areas E, S and G internally with the specialist teams and externally the inquiries about sustainability.


Climate action and environmental protection are among the main challenges of the 21st century facing society and businesses.


Housing and functioning infrastructure are some of the most basic human needs. However, a material percentage of CO2 emissions stem from housing stock.
Instone Real Estate’s business activities are therefore associated with a material impact on the environment, both direct and indirect.

In future we will successively analyse and improve our environmental footprint. In terms of our own business activities, this includes issues such as the vehicle fleet, paper consumption and the energy usage of buildings used by Instone itself. 


Social responsibility

Instone Real Estate views itself as part of society and would like to make an active contribution to the positive development of society as a whole.

Responsibility is firmly rooted in our corporate culture and therefore in the day-to-day actions of the Group. Instone Real Estate is aware of its impact on society and the environment and wants to contribute to positive development with its projects.

Instone Real Estate is aware of the impact it has on society and the environment, and aims to make a positive difference with its projects. This includes engaging via the media, services and the knowledge of our employees and financially where help and support is required outside the Company, for  instance for the creation of a lively residential district..

As a good corporate citizen, Instone Real Estate also takes action especially in locations where the Company has projects. Organisations and initiatives that promote the neighbourhood, the development of social service facilities in an urban district or make infrastructure improvements are our preferred efforts to support.

Corporate Social Engagement



As one of Germany’s leading real estate developers, we are confident that we will be able to successfully pursue our business model in future only if we act responsibly for the long term. 


In the 2020 reporting period, we further deliberated on defining specific activities and topics relating to our understanding of our social engagement and will continue to do so in 2021. 

Against this backdrop we would like to provide a glimpse of the responsibility we have taken for social projects in addition to our involvement in projects and neighbourhoods and the associated infrastructure such as daycare centres and school places.


Human rights

Respecting human rights is an integral part of our responsible corporate governance efforts.

We require respect for all human rights along our entire value chain from our own Company as well as from our business partners. We expect that all participants will meet their duty of care with regard to human rights.

The core values of lawful and ethical behavior are summarized in a group-wide Code of Conduct . His specifies existing duties and responsibilities and derives various codes of conduct on the basis of the law or existing official instructions. 

The code of conduct offers employees, service providers and contractual partners of Instone Real Estate orientation and assistance in their day-to-day work and interactions. It also sets out values to which Instone Real Estate is expressly committed.

Although our Code of Conduct covers many different topics, it is possible that laws could be violated or duties could be breached. Our employees can report violations or suspected violations of the law, statute or Company guidelines and rules to their supervisors, the Compliance Officer, a whistle blower hotline or an online whistle blower portal 


Cooperation Partners

We are aware that there are sustainability risks throughout our entire supply chain.

Our aim is to promote sustainability throughout the supply chain, increase transparency and therefore further minimise procurement risks.
