I have written an attempt at a guide about how to measure the carbon footprint of a scientific conference (or other event). This is largely inspired by the computation of the carbon footprint of the AGU 2019 Fall Meeting, and also by our experience computing the carbon footprint of SWERC 2019–2020.
This blogpost is published on the blog of the TCS4F initiative, an attempt by theoretical computer scientists to reduce the carbon footprint of our activities and help mitigate the climate crisis. I'm involved in the initiative (mostly as an author of blog posts, for now) and I have signed their manifesto: I encourage you to do the same if you agree with taking action on this important issue!
In any case, head here to read the blog post!
