Direction of the focus area

We will responsibly and efficiently reduce resource use and carbon emissions that cause global warming.

Targets

  • 15% in energy savings per square meter in 2025, compared with the 2015 index and energy savings of >1.5% yearly in the like-for-like portfolio.
  • Net-zero carbon emissions and 100% non-fossil fuel energy by 2030
  • 100% of all vehicles to be non-fossil fuel powered by 2020
  • 1% water conservation per year in the like-for-like portfolio

Outcome

  • 8% savings (1%) cf. 2015 and 8% reduction (3% increase) in the like-for-like portfolio
  • 77% (81%) less CO2 emissions from property management (Scope 1 and 2) since 2007*. For monitoring of Scope 3, see Background data. 96% (95%) renewable energy
  • 86% (62%) non-fossil fuel powered vehicles, which is in line with the goal of achieving 100% in 2020
  • 3% water conservation (1%)

*As of 2019, Castellum reports the trends for scopes 1 and 2 separately from Scope 3.

Efficient use of resources

Castellum’s efforts to reduce the company’s climate impact are ambitious, and are in progress throughout operations. The ambition of working efficiently to develop a more sustainable property portfolio has been a goal of the company since the mid-1990s. This work has yielded results, and Castellum is now among the most sustainable companies in the industry.

To future-proof Castellum’s property portfolio and promote the sustainable development goals established by the UN and prioritized by the company, several challenging goals have been set. Buildings must be more energy-efficient, natural resources must be more efficiently utilized, biodiversity in urban environments must be increased, renewable energy must be improved and changing weather conditions must be taken into account. Castellum is involved in the climate plans and policies of its customers and of government agencies. It supports international treaties such as the Paris Agreement, displays leadership and to the greatest extent possible influences the industry to reduce its climate impact. Castellum is the first property company in the Nordic region to have its climate targets approved by the Science Based Targets (SBT) initiative. 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. Despite the strong possibilities we see for adjusting emissions from property management (scopes 1 and 2), there are major challenges to achieving climate neutrality in Scope 3. At present, we are far from having all the solutions to becoming climate neutral by 2030. But we know that ambitious goals drive innovation.

More efficient energy use

Castellum works continuously to reduce energy use by optimizing operations and investing in energy-efficient technologies. Over the past year, 74 developments comprising MSEK 70 were implemented for the purpose of enhancing efficiency. Energy use within the Group is systematically monitored and then analyzed. The measures implemented are prioritized in order of greatest potential for enhancing efficiency.

Target and outcome, energy consumption per SQ. M. (Bar Graph)

The actual change in the like-for-like portfolio was -8%. Castellum began systematically measuring energy consumption and heating in 2007, which is why it is utilized as a comparison year.

Expansion is underway for Castellum’s own portal for web-based property monitoring, to check values for operations, alarms, elevators and entries. This project saves energy and time, and simultaneously provides customer benefits in the form of better services through preventive measures. At present, 424 properties representing 3,164,000 square meters are connected to the portal.

In 2019, the normalized energy consumption for heating and property electricity in the comparable portfolio (like-for-like) decreased 8% year-on-year. The efficiency enhancements are due in part to active work to reduce energy use in Castellum’s buildings, and in part to milder weather in 2019 compared to the preceding year. Heating use decreased 7% in 2019, while electricity use decreased 10%. Since 2007, energy consumption has decreased by a total of 32% per square meter. Castellum’s heating consumption of 60 kWh per square meter can be compared with the industry average, which uses the Swedish Energy Agency’s reference value for heating premises of 122 kWh per square meter. This means Castellum’s buildings are 51% more energy efficient than the Swedish average for these premises.

Increased share of renewable fuels

Of Castellum’s total carbon emissions, 7% can be directly influenced by oil, gas, and service, benefit and pool vehicles (Scope 1); the remaining 93% – for example, purchased energy such as district heating and electricity (Scope 2) – can only be influenced indirectly.

To reduce emissions, work is underway to phase out fossil fuels; currently four oil furnaces are still in operation. Approximately 12% of Castellum’s customers are responsible for their own heating and 23% for electricity on the property. A total of 1,720 kW of solar cells have been installed on Castellum’s properties, equivalent to a total of approximately 12,040 square meters of solar cells. Four large solar cell installations were built in 2019.

Castellum’s use of district heating means that its carbon emissions are dependent on the fuel mix used by the district heating facilities. At present, Castellum makes use of 27 district-heating facilities, which represent 93% of the Group’s total emissions under scopes 1 and 2. Castellum is in dialogue with the district-heating suppliers with the highest carbon emissions per kWh in order to influence these suppliers to reduce emissions. The transfer to green district heating with renewable fuels is ongoing and currently amounts to 59% of our district heating suppliers.

During 2019, scope 1 and 2 carbon emissions increased by 23% per square meter; since 2007 they have decreased by 77% per square meter. The increase is largely due to an increase in emissions from district heating suppliers during the year. Of Castellum’s total energy use, 96% is renewable.

Since 2001, only green electricity has been used in the Group.

Reduced amount of waste

Castellum has long worked actively to reduce the amount of waste that goes to dumps by offering household waste sorting facilities. Monitoring the work is complicated by several sanitation companies being hired, only a few of which can report follow-up in terms of weights. In addition, customer operations differ, which means their needs for waste management differ as well. Statistics are currently obtainable from 27% (24%) of the sanitation companies and Castellum is working actively to increase the amount of available data. The statistics include waste from buildings managed by Castellum, but not waste from projects or construction contracts.

Water consumption

Castellum utilizes water from the municipal water system, monitors consumption and takes measures to reduce it.

In 2017, Castellum adopted the objective of reducing water use per square meter in the like-for-like portfolio by 1% per year up until 2030. Conservation in the like-for-like portfolio was 3% year-on-year.
