How to EGU22: Five ways you can help us make a greener EGU22!

For several years, EGU has committed – both in terms of resources and research – to helping to create a cleaner and greener environment. As our biggest event of the year (EGU22) soon approaches, nearly 10,000 people are expected to travel to Vienna for the week-long conference. An event of this scale can of course impact the environment any number of ways. The good news? Even the smallest of actions can help mitigate this impact and make a difference to our environmental footprint, and you can support us in this mission!

We list five ways that require just a little planning ahead to support EGU’s green initiatives. Read on to discover how you can help.


#1: Prioritize eco-friendly travel

If you are travelling to Vienna, we recommend making conscious choices when it comes to your travel – whether this is to and from Vienna or even travel within the city. The Austria Center Vienna (ACV) is well accessible by all modes of transport, which can be compared using the website Instead of private vehicles, choose the city train, bus, or metro whenever possible – made even easier by the free public transport pass that all on-site attendees are given as a part of their registration fee! You can also bike to the conference center (bicycles can be rented through CityBike Vienna, Donkey Bike, or Copa Cagrana Rad und Skaterverleih) and if you’re feeling adventurous, how about a walk?

#2: Embrace the digital life, it’s 2022!

EGU22 will combine all the best elements of our previous virtual General Assemblies with the pre-pandemic on-site experience – this means exciting new ways to communicate digitally. Some simple ways to do this include creating an online personal programme using the EGU22 website (avoid printing programmes) and sharing your messages/material through scannable QR-codes (avoid the distribution of flyers or other printed materials). If you have other suggestions to support EGU’s digital initiatives, please let us know in the comments below.

#3: Pack reusable products

Did you know that since 2018, EGU’s move to encourage reusable water bottles has saved about 30,000 single-use PET water bottles per year? This is based on the number distributed in 2017. As organisers, we do our best to minimize waste as much as possible, but our attendees can make a big difference here! With a little planning, you can ensure a well packed bag with essentials like reusable water bottles, coffee cups and mugs, straws, and cloth napkins. Biodegradable waste bags are also a good idea, as well as reusable food containers that replace throw-away containers. For more ideas, check out this blog or read this article for inspiration.

#4: Adhere to the Center’s waste practices

The Austria Center Vienna, our host in the city, particularly welcomes and certifies green meetings. Over the years, the Center has introduced several initiatives to reduce its environmental impact. Some of these include the use of energy-saving LEDs, a solar array to heat the water used in the kitchens and toilets, and working with an in-house catering company compliant with green standards. During EGU22, we advise all participants to follow the Center’s practices on waste segregation and the reusing of personal cutlery during the conference. There will be physical signs displayed to guide you at all times, but if ever in doubt, just ask a member of the support staff or the event organisers.

#5: Join the discussion!

If you would like to learn more about sustainability and the latest research to mitigate climate change, we encourage you to participate in the TM8 townhall session “Exploring the nexus of geoethics and climate change education,” taking place on 24 May, 19:00–20:00 (CEST). This Townhall aims to start a wide-ranging conversation to bring these two interdependent areas closer together. You can also look out for the ITS4 session – “Local solutions that have global impact: mitigation measures in geosciences to reduce the global temperature increase.” This includes topics like ITS4.2 “Solutions for a resilient natural environment: opportunities and challenges of ecosystem services assessment” and ITS4.4 “Nature-Based Solutions and Climate Engineering in Climate Governance.”


We hope this blog has inspired you to make a difference to the environment in ways big and small! In closing, we’ll leave you with a few initiatives that EGU has been putting in place toward a greener General Assembly:

  • We no longer print a paper programme book and instead encourage attendees to access the programme online and/or through smartphones. This has saved about 1 million printed A5 pages per year since 2018!
  • The daily newsletter EGU Today went to fully digital in 2019, saving 15,000 double-sided A4 printed pages per year and remains a popular source of information throughout the week. Make sure to check it regularly from Sunday 22 May to Friday 27 May here!
  • EGU note pads and flyers are printed on FSC-certified recycled paper, offsetting the environmental impact of producing the flyers on regular paper.
  • Since 2020, EGU pens distributed at the EGU booth are made of bamboo rather than plastic.
  • Name badges consist of lanyards made of 100% recycled PET and a paper badge made of 100% FSC-recycled paper. Since 2020, the paper badges are no longer pocketed in a plastic sleeve. Attendees are also encouraged to bring their EGU lanyard from a past conference or, if taking a lanyard this year on site, return it at the end of the conference or keep it for next year.
  • The meeting’s 1,500 sqm of signage is made from polyurethane hard foam (PU). We reuse these signs for 3 to 5 years and limit the production of new ones. These signs are stored directly in the ACV to avoid transport.
