The climate check with A&O's CO2 calculator

A&O's CO2 calculator for study groups


A&O wants to contribute to environmentally friendly travel by giving school classes and teachers the opportunity to inform themselves about their carbon footprint, climate change and sustainability here A&O Info portal (German only).

In order to make the issue fun and entertaining to students, you can try out your newly acquired knowledge using our CO2 quiz (again, German only) and earn discount codes for your next A&O accommodation.

  • Did you know what planet has got the largest amount of CO2 in the atmosphere?
  • Or what happens when water and CO2 come into contact?

We want to promote awareness of independent, climate-conscious behavior and thereby act as a motivator, not as a "party pooper".

Example of a climate-friendly school trip to Vienna:

A particularly environmentally friendly group of students from Sarajevo has documented their class trip for us. They have travelled by bus, ate 60% vegetarian food and selected activities that could be explored on foot or by bicycle. In the evening they have kept themselves entertained with board games, our hotel piano, billiard, table football and our A&O PhotoFunBox.

We are setting a good example!

The past years we have instructed an independent institution to check all our buildings on their CO2 emissions. This CO2 emission check allows a measurement of the climate impact on human activities. The average level of CO2 emissions of all A&O hostels is 8.96kg CO2/ overnight stay. This value in fact corresponds to the climate efficiency class B in the categories youth accommodations, being 3 times lower than in other two and three star hotels. The average value is 26 kg CO2/ overnight stay. We can achieve this climate friendly value by means of our simple and functional facilities plus our optimal use of space.
