Making the heat supply to DB buildings more climate-friendly and no longer using fossil fuels wherever possible is another lever for achieving our 2040 climate protection target. In 2024, we made progress with the heat transition No. 97 by replacing a total of 19 old heating systems at our prioritized locations with more climate-friendly alternatives (such as heat pumps or biomass heating). Among other things, we converted the Osnabrück and Hamburg-Stellingen stations from heating oil and natural gas to heat pumps, and connected Jena West and Pforzheim to district heating. We have also started planning the conversion at more than 20 other locations.
