We create the sustainable cities of the future

Castellum has a strong focus on sustainability. 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 three areas of focus: Future-proofed assets, Sustainable workplaces and Sound business. Based on 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 23 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).

Focus areas

Future-proofed assets

We will responsibly reduce our impact on the climate and biodiversity while increasing resource efficiency, promoting the circular transition, and developing a sustainable and future-proofed property portfolio in a changing world.

Sustainable workplaces

We will develop sustainable, attractive, and inclusive workplaces that promote the health and well-being of our employees and customers.

Sound business

We will conduct our business responsibly towards our society and stakeholders by setting clear requirements for our supply chain.

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.

Terms: LTI = Lost Time Injury, LTIR = Lost Time Injury Rate and TRIR = Total Recordable Injury Rate 

  1. No fatalities have occurred, which is why fatalities were not divided up according to workplace illness or workplace accidents, nor is any fatality rate reported.
  2. Serious injuries with more than six months of recovery, excluding fatalities. 
  3. Castellum’s interpretation of GRI’s “Work-related ill health”.
  4. The number of hours worked for contractors is based on an assumption that 60 per cent comprises labour costs at an hourly price of SEK 500.
