Since 2008, PKA has reduced its CO2 footprint by 85% in its Danish real estate portfolio, and by the end of 2025, there must be a further 50% reduction. The aim is to contribute to a greener housing stock in Denmark, but also secure an attractive and sustainable return to the members of the pension fund.

About a quarter of the world’s total CO2 emissions can be sourced back to building and operating properties. If the Paris Agreement is to be complied with, the climate impact of properties must be reduced.


When possible, PKA certifies properties with systems such as the DGNB (of The German Sustainable Building Council) and the LEED rating system (of the U.S. Green Building Council), where the entire building process from planning to deconstruction is obligated to fulfill various requirements and measures.

The pension fund continuously renovates existing properties and builds new ones according to the highest climate standards. Solar cells and wind turbines ensure direct energy savings and CO2 reduction, a better indoor environment, and efficient stewardship when it comes to daily maintenance.


From 2008 to 2020, the CO2 footprint in PKA’s Danish real estate portfolio has been reduced from 25,000 tons CO2 to an annual footprint of only 4,100 tons.
