…another ArXiv paper on “The carbon footprint of large astronomy meetings”, compares the annual meeting of the European Astronomical Society held physically in France in 2019, but online in 2020. They conclude a 3000-fold reduction in C footprint resulted. Full paper also in Nature Astronomy.
Presumably the BAA’s C footprint has also reduced, but less so since few members travel by air. Nevertheless, I am longing for the time we can meet F2F again….
