About Castellum
Castellum’s agenda for the sustainable city 2030
Our vision for our sustainability initiatives is to be, over time, the most sustainable property company in Europe and actively promote sustainable development. One of our sustainability goals is to become entirely climate neutral by 2030.
We create the sustainable cities of the future
Castellum works sustainably. We are reducing our environmental impact, we work on energy efficiency, and we certify our properties for sustainability. We are a long-term community developer. Sustainability is integrated into everything we do. And in all of our investments.
We regard laws and regulations as minimum requirements, and strive for continual improvements. Castellum is a responsible community developer, and we drive development forward. “The sustainable city 2030” consists of four areas of focus: The Planet, Future-Proofing, Well-Being and Social Responsibility. Based these areas of focus, Castellum conducts its operations responsibly and creates long-term solutions from an economic, ecological and social perspective. By 2030, Castellum will have net-zero carbon emissions. In 2017, the Board of Directors adopted a concrete sustainability strategy – The sustainable city 2030 – with 21 measurable targets that are revised and updated annually. The majority of the targets are monitored and reported quarterly. The climate-related goals that Castellum has adopted have been approved by the Science Based Targets initiative (SBTi).

Sustainability initiatives are integrated into everything we do
Castellum should promote sustainable development, and its sustainability goals should be integrated into its operations, yielding tangible results. This work permeates the entire business. Corporate social responsibility is crucial to the company’s success and drives profitability and the development of long-term shareholder value. Key starting points for our sustainability initiatives are the ten principles of the UN Global Compact – which we support and have signed on to – as well as the Paris Agreement, and we actively promote the efforts to realise the UN Sustainable Development Goals.
