Dear ASA members,

We invite you to join for a special Zoom colloquium on Wednesday 9 March at 1 pm AWST / 4 pm AEDT by Jürgen Knödlseder (IRAP, Toulouse). Jürgen will be discussing the study he recently led in assessing the carbon footprint of astronomical research infrastructure<https://protect-au.mimecast.com/s/HDlZCANpgjCNw4m73cQlV8U?domain=arxiv.org>, to appear in Nature Astronomy. This work builds on the momentum generated worldwide to push for the decarbonization of astronomical research, and we hope it is therefore of interest to each and every ASA member.

All are welcome and encouraged to join. Please feel free to share with your department mailing lists for those who are not yet ASA members.

The title and abstract for the talk and paper are below, as is information for the Zoom connection (or just use this link<https://protect-au.mimecast.com/s/RpQeCBNqjlC7wjZE9u18YDZ?domain=uwa.zoom.us>).

We will endeavour to record the talk for those who cannot attend live.

Best,
- Adam (on behalf of the ASA Sustainability Working Group)

Estimate of the carbon footprint of astronomical research infrastructures
The carbon footprint of astronomical research is an increasingly topical issue with first estimates of research institute and national community footprints having recently been published. As these assessments have typically excluded the contribution of astronomical research infrastructures, we complement these studies by providing an estimate of the contribution of astronomical space missions and ground-based observatories using greenhouse gas emission factors that relate cost and payload mass to carbon footprint. We find that currently worldwide active astronomical research infrastructures have a carbon footprint of 20.3 +/- 3.3 Mt CO2e and an annual emission of 1169 +/- 249 kt CO2e/yr, corresponding to a footprint of 36.6 +/- 14.0 t CO2e / yr per astronomer. Compared to contributions from other aspects of astronomy research activity, our results suggest that research infrastructures make the single largest contribution to the carbon footprint of an astronomer. We discuss the limitations and uncertainties of our method, and explore measures that can bring greenhouse gas emissions from astronomical research infrastructures towards a sustainable level.
Bio
Jürgen studied at the TU Munich and MPE in Garching and then moved to IAP, Paris and subsequently IRAP, Toulouse. He has been a CNRS staff scientist since 2001. Jürgen works in the field of gamma-ray astronomy on data analysis and instrumentation, initially using COMPTEL and INTEGRAL/SPI on the topics of nucleosynthesis and antimatter, followed by Fermi and more recently CTA on the topics of cosmic-ray physics. He chaired the CTA consortium board for 9 years and recently stepped down to focus on sustainability issues in astronomy. Jürgen recently completed a training on carbon footprint analyses.
