Sustainability is important to us in all areas, which is why we also pay attention to it in procurement and disposal as well as with our partners.

Cooking oil disposal

In Vienna, more than 320,000 kilograms of used cooking oil are disposed of every year. This is used to produce 100 percent carbon dioxide-neutral biodiesel. This saves more than 880 tons of carbon dioxide annually. For the same amount of diesel from rapeseed oil, a cultivation area of 9.54 km² would be necessary.


We are also proud of the fact that we collect and hand in all our used cooking oil in so-called "Wöli containers" and in this way also contribute to sustainability.

Public accessibility

Switching to public transport saves up to 1,500 kg of CO2 per year, which is about 8,300 kilometres not driven by an average car. Or to put it another way, this saving replaces the cleaning power of 120 trees!


The Luftburg - Kolarik restaurant in the Prater is so centrally located that we have perfect connections to the public transport network. The double benefit is that you can travel in an environmentally friendly way and enjoy your beer (or several) with a clear conscience at our place without having to worry about driving afterwards!

100% hydropower

The restaurant Luftburg - Kolarik in the Prater is supplied by Wien Energie Vertrieb GmbH & Co KG with 100% electricity from hydropower and guaranteed without CO2 emissions. Through environmentally friendly supply with renewable energy, we help to significantly reduce CO2 emissions.
