Our commitment

We take our ecological responsibility very seriously. This is why TAG is already implementing its own goals in various business areas. We invest continuously in the maintenance and modernisation of our portfolio. The focus here is on energy and emission-reducing measures in and on buildings, building technology and heating systems. In 2023, TAG invested approx. EUR 126 million in its portfolio in Germany alone, including maintenance expenses. These investments comprise around 1/3 of our rental income.


More than 42,000 trees grow on our properties, which not only positively influence the quality of stay in the neighbourhood, but also store around 1,000 tonnes of CO2 annually. The amount of CO2 saved in this way corresponds to approx:

  • the consumption of a car (petrol engine) travelling 3.3 million kilometres or
  • approx. 1,000 passenger flights from Frankfurt/Main to New York or
  • 8.8 million cups of coffee.

Around 80% of our office locations are supplied with 100% certified green electricity.
