To assess the emissions for all meetings, we used the Travel Carbon footprint calculator programmed by Didier Barret (travel-footprint-calculator.irap.omp.eu), which can also be used to find an emission-minimized meeting location.

For more details, check out the paper, published under open access in PNAS Nexus (doi.org/10.1093/pnas...). We hope that our article encourages more conversation about the meeting culture in academia and are very interested in constructive discussion 💚
