The impact of astronomy on climate change

The global climate crisis has prompted the astronomy community in recent years to assess, primarily, the impact of its activities upon climate change, and secondarily, the impact of climate change upon astronomy. This Collection contains articles that have appeared in Nature Astronomy related to these topics, starting with preliminary inventories of greenhouse gas emissions arising from professional activities, including: work-related travel and conferences, the operation of supercomputers and observatories, the construction of astronomical facilities, the launch of space missions, and other sources. Taken together, these articles demonstrate that the research community needs to take rapid action, changing the ways it conducts science, in order to limit the impact on the climate and create a sustainable future for astronomy.
