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 2021, TAG has already invested 107 million euros in its own portfolio and could increase this investment to 124 million euros in 2022. These investments comprise around 1/3 of our rental income.


More than 43,000 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 half of our office locations are supplied with 100% certified green electricity.
