astronomy carbon footprint (IMAGE) PNAS Nexus Caption A map showing the distribution of all 2019 astronomy/astrophysics meetings around the globe. Conferences are shown as circles and schools are shown as squares. The size of each marker corresponds to the overall amount of GHG emissions related to travel to each meeting, while the color-scale indicates the mean emission per participant for each meeting. A darker color implies a higher carbon footprint per person, which is related to travel over larger distances.
