The Katowice Climate Change Conference just ended and I’m taking this as an opportunity to reflect on academic carbon footprints. Given how much more carbon-heavy air travel is than any other means of transport, and how limited train connections are where I’m based, my academic carbon footprint is huge, even though I do my best to minimize my personal, I will write a couple of posts on this topic, starting with a retrospective review of my year in travelling and travel decisions.
