Green Meeting

The STS Conference Graz is a Green Meeting

The STS Conference Graz is committed to climate protection and sustainability. That’s why we chose to get certified by the Austrian Ecolabel for "Green Meetings and Green Events". The Green Meeting certification process helps to identify areas where sustainability can be improved. Our goal is to make the conference as eco-friendly as possible.


What makes the STS conference a Green Meeting?

In order to get certified as a Green Meeting, an Event has to fulfil several criteria (see here). The STS conference Graz committed to the following criteria, amongst others.

  • The event location allows for car-free transportation to the venue
  • Participants will be informed about options for climate-compatible travelling to and from the event venue
  • Side-events are within walking distance or can be used by public transport or a share-ride shuttle service
  • All proposed accommodations are located at walking distance or accessible by public transport
  • Greenhouse gas emissions arising from the travels are calculated (see below)
  • Participants are encouraged to engage in greenhouse gas compensation
  • Event times are adjusted to allow for public transport to the event
  • Badges are collected after the event and kept available for reuse
  • Any printed products of relevance to the event are produced according the principle of minimum resource expenditure: small number of copies, small printing format, double-sided copies, replacement by electronic carriers, mail services, internet, apps etc.
  • Paper used for printing jobs is Eco-labelled according to ISO type I33
  • Giveaways that produce large amounts or environmentally harmful waste are note distributed
  • The catering is completely vegetarian and is comprised of regional and seasonal food and drinks
  • Tableware is reusable
  • 100% of electricity is generated by renewable energy sources
  • Participant’s feedback on their conference experience is collected


Greenhouse emissions of the STS Conference Graz 2019.

Sixty-two conference participants answered our survey on the distances and modes of transport to and from the STS Conference Graz 2019. Analyses show that the largest amount of distance (50%) to and from the conference was covered by long-distance flights.

To estimate the total amount of emissions generated by travel to and from the STS conference 2019, we extrapolated the survey data to the number of conference participants who were not living in Graz (N = 174). The results were multiplied by the emission factors for the different modes of transportation provided by the Environment Agency Austria.1

Results show that most of the emissions in CO2 were generated by short- and long-distance flights, amounting to a total number of emissions around 123 tons CO2.2


To bind the total amount of CO² generated by travel to and from the Graz STS Conference 2019 (123 tons) within one year 25 football fields of grown spruce trees would be needed.

Greenhouse emissions in CO2equ/passenger-kilometeres: Train: 14g, Bus: 52g, Car: 178g, Short-distance flights (<= 750 km): 767g, Long-distance flights (> 750km): 390g according to the Environment Agency Austria for 2017.

Due to the small sample size of the survey, the extrapolation is rather inaccurate. Calculating the 95%-confidence interval of extrapolated emissions even results in a potential maximum of approx. 230 tons CO2.
