(Fun) Facts

WU is committed to protecting and advancing environmental sustainability on its campus. As an institution, the university is certified by EU Eco-Management and Audit Scheme (EMAS) as well as ISO 14001:2015. WU is actively engaged in offsetting its annual CO2 emissions as well as in raising awareness of our consumption of energy and resources (note, for example, the real-time WU Energy Screen in the entrance area of the TC Building). More details can be found on our Campus Management website (in German) and in the relevant reports.

There are many ways in which WU seeks to set an example as a socially responsible university. Its family friendly, barrier-free campus, active engagement in Occupational Health Management (if you are staff or faculty, visit the Well-Being@WU SharePoint page in German), and external cooperation with the United Nations Industrial Development Organization (UNIDO) are a few of its many concrete initiatives to make responsibility a lived value and practice.

Here are some interesting facts about our campus life:*


200,000 — the number of avocados one could grow with our university’s annual water consumption of 62.5 million liters (2019 est.). Our tip: It is up to each of us to use water sparingly and responsibly. We should also inform ourselves about, and raise public awareness of, the so-called “hidden” water usage (amount of water required in manufacturing products and foods).

Basketball matches

15,000 — the number of complete basketball games that could be played over the course of the 10,000 hours (2019 est.) WU students contribute annually to Volunteering@WU in supporting youth from disadvantaged socioeconomic backgrounds with afterschool tutoring and joint music performances. Our tip: Become a study- or music buddy! We guarantee you will learn more than you teach.

Tapei 101

3 — how many Taipei 101 towers one could cover using the 1.5km of tactile paving on the WU campus that helps people with visual impairments. WU also operates 90 audio induction loop systems in its lecture halls and event rooms to stream directly to the hearing aids of the hearing impaired. There are more than a 100 barrier-free restrooms and showers. Our tip: Think about how you can contribute to fostering inclusive study, work environments at WU and the BeAble program!

female professor

1989 — the year the first female professor at WU, Renate Rathmayr, was appointed at the Institute for Slavic Languages. Today, 29% of WU professors are women (see here). To keep this number growing, the Female Scholar Program supports early career researchers, and the Wise Women of WU mentors WU alumnae on career planning. Our tip: Insights on gender sensitive language usage are provided in WU’s official guideline (in English and German). Have a look!


21 — the number of Apollo 11 Space Shuttle crews represented by the 63 essential workers (staff of the external service provider Götz) who keep WU's buildings and grounds in excellent condition. This team encompasses 11 different nationalities and speaks double that number of languages. During the nationwide COVID-19 lockdowns, the cleaning staff not only continued but also intensified its disinfection operations. Our tip: Saying "hello" and "thank you" is the least we can do.

100 percent offsetting

Our campus is carbon neutral! Of course, this does not mean that WU emits no CO2. In fact, our university’s emissions are proportionate to its size—at around 655 tons a year (2019 est., excluding faculty travel). However, WU offsets this number by supporting three sustainability projects. Our tip: Although WU actively strives to reduce its carbon footprint as an institution, you still can make a difference. If you can, join the 25% of our WU members who already bike or walk to campus.

Wiener Riesenrad

430 tons — how much the Wiener Riesenrad in Prater weighs, similar to the total number of tons of annual waste generated on our campus (2019 est.). WU’s waste-reduction initiatives include waste separation and recycling options as well as awareness-raising campaigns, such as Bring Your Own Box or the Vienna-wide reusable coffee cup system. Our tip: Support our Environmental team's efforts, respect the work of our cleaning staff, and do not forget that small steps lead to big changes.
