Sustainability involves creating long-term solutions from economic, ecological and social perspectives, and refining these values through our operating processes.

In addition to taking responsibility and creating value for our society, the planet and future generations, Castellum’s sustainability efforts also provide the Group with a competitive advantage. Moreover, well integrated sustainability efforts contribute to better management and improved control of our properties. This means more satisfied customers, dedicated employees and increased profitability. In other words, sustainability is about taking the right decisions today so that the stakeholders – on whom Castellum’s operations depend – will choose Castellum in the future.


Castellum’s sustainability activities form an integrated and natural part of the Group’s business operations. Over time, Castellum will be one of the leading companies within the field of sustainability and actively promote sustainable development. Castellum sees society’s laws and regulations as minimum requirements and strives for continuous improvements to reach clearly stated goals in order to promote sustainable development. Castellum will help drive development forward by taking corporate social responsibility.


Operations will contribute to sustainable development, and sustainability efforts will be integrated with all business actions and result in tangible results. Sustainability efforts will permeate all business undertakings such as ownership, management, portfolio development, customer relations, employees and financing. Operations conducted in a responsible manner are vital for the company’s short- and long-term success, as sustainability action drives profitability and long-term shareholder value.

All business operations will be characterized by high skills levels, good business ethics and benchmark assumption of responsibility.

Our position on climate change and the environmental limits of the planet

Castellum acknowledges the scientific evidence that human activity accelerates climate change. Breaching the planet’s environmental limits poses great risks for our future. To contribute to the global agenda, Castellum will therefore guide and target business operations in accordance with the UN Sustainable Development Goals and the Global Climate Change Agreement.

In order to future-proof Castellum’s portfolio, buildings are to be energy-efficient; life-cycle perspectives have to be considered when investing; responsibility will be taken for natural resources and biodiversity; the proportion of renewable energy will increase; and operations are to be adapted to mitigate climate change. Castellum will be committed to customer and government climate plans and policies. Castellum will remain at the forefront and, as far as possible, inspire our entire industry to become more climate-friendly.


As a responsible social developer, Castellum will be involved in pushing development forward toward a sustainable society. Castellum considers the precautionary principle and society’s requirements in the form of legislation and regulations as minimum requirements, and the Group strives for continuous improvements in order to promote sustainable development.
To achieve well-functioning sustainability activities, Castellum will,


  • Manage operations in accordance with the UN Sustainable Development Goals that we are able to influence.
  • Comply with Castellum’s Code of Business Conduct, which is based on the UN’s Global Compact principles. All Castellum employees and partners are to understand and comply with their respective codes of business conduct.

  • Regularly monitor, report and improve our work.

Ecological sustainability

Organization and governance of sustainability efforts

A joint operational sustainability group develops activities, shares experiences and monitors relevant changes in the global environment. There is also a Sustainability Forum with the aim of updating and integrating development efforts into Castellum operations. The Sustainability Forum consists of managers from the core business: HR, Project Development, Executive Management, Regional CEOs, Finance and Purchasing.

Castellum’s sustainability efforts require committed and skilled employees; further training in sustainability issues is therefore offered on a regular basis. The ambition is that all new employees will undergo introductory sustainability training.
