About Castellum
The Nordic region’s most sustainable property company
Castellum is the Nordic region’s most sustainable property company, and sustainability initiatives are fully integrated into our operation.
Long-term community developer
Sustainability initiatives permeate ownership, property management, asset portfolio development, and financing as well as relationships with tenants and employees. We believe in the idea of responsible entrepreneurship. In creating economically, ecologically and socially sustainable solutions. As a long-term player and community developer, promoting the development of a sustainable society is a natural part of our work. Sustainability is usually divided into three dimensions: ecological, social and economic sustainability.
Three dimensions in sustainability

Ecological sustainability
For Castellum, this means using resources such as energy and water as responsibly and efficiently as possible, and that new construction, extensions and reconstructions are carried out in accordance with high environmental standards.

Social sustainability
Social sustainability concerns the long-term development of a society that puts people’s needs and wellness in focus. This means that we aim to be a committed party where we operate and collaborate with tenants, municipalities and other partners. We collaborate with schools and universities to offer young people internships and summer jobs. And – naturally – we take care of our own employees.

Financial sustainability
Concerns securing long-term growth while minimising any negative consequences for ecological and social sustainability. Our long-term sustainability strategy provides a natural foundation for economically sustainable growth. Castellum’s vision for its sustainability initiatives is to be the most sustainable property company in Europe and to promote sustainable development.
