In 2020, Castellum continued to receive international recognition for its sustainability efforts. The awards are proof of the company’s strong position in sustainability, creating continued drive for leading development in the industry.

Dow Jones Sustainability Index

For the fifth consecutive year, Castellum retained its position as the only Nordic company in the property and construction sector on the Dow Jones Sustainability Index (DJSI), which includes the companies in all of the world’s industries that are the best performers in the field of sustainability. Every year, the DJSI – owned by S&P Global – invites over 3,500 listed companies in all industries internationally to take part in the evaluation. The top performers globally qualify for this prestigious index, established in 1999 for the purpose of steering investors towards more sustainable investments. Castellum is one of seven Swedish companies that qualified for the index.

Named first in the world by GRESB

Every year, the Global Real Estate Sustainability Benchmark (GRESB) conducts a global review of sustainability efforts in major property companies and funds; 1,200 property companies around the world took part in this year’s study. For the fifth consecutive year, Castellum was named a global sector leader, which means it ranks first in the world in the office and industrial premises sector.

The European Public Real Estate Association (EPRA) works to improve standards and transparency in the property industry in order to strengthen credibility and thus increase security for investors. The prize for the best sustainability reporting in Europe, EPRA Gold, is a recognition that Castellum both does what it promises in the area of sustainability and additionally is clear in its communications.

Climate targets approved by SBT

Castellum is the first property company in the Nordic region to have its climate targets approved by the Science Based Targets initiative (SBTi). Castellum’s target is to achieve 100% climate neutrality in its operations by 2030, thereby supporting the UN’s climate agreement and the national ambition for a fossil fuel-free Sweden.


In 2020, Castellum was ranked AA (on a scale of AAA to CCC) by the MSCI ESG ratings assessment.

Europe’s most equitable listed companies

In December, the company took part in one of the UN’s equality forums, at which Castellum’s equality initiatives were described; during the year, this resulted in Castellum being ranked by European Women on Boards as Europe’s most equitable company out of 600 listed companies in Europe.
