Astronomers for Planet Earth (A4E) is an international grass-roots movement of astronomers (scientists, students, educators, and amateur astronomers) who work together to address the climate crisis from an astronomical perspective. While some of us focus on incorporating the topic of climate change into their curriculum or outreach activities, others are working on assessing the carbon emissions in connection to the Astronomy profession. An overview of published work separated by categories (inkl. hyperlinks to each publication embedded in its title) can be found here (last updated June 2024).In addition, you can also find a lot of information in the book Climate Change for Asronomers - Causes, consequences, and communication, or the New York Times article titled Alarmed by Climate Change, Astronomers Train Their Sights on Earth.
I am an active member of A4E since 2021 and have mostly been involved with analysing the emissions related to astronomers travelling to (international) conferences. Together with several A4E members from different countries, I have published the results of our quantitative analysis from conference travel in the year 2019 under the title Astronomy’s climate emissions: Global travel to scientific meetings in 2019 in the journal PNAS Nexus. In addition to the assessment of the travel emissions, we also discuss how meetings including an online component are more accessible and inclusive for entire scientific community.
