It’s 2020 and Christoph Kueffer is now into his fifth year of (almost) not flying. Whereas not flying hasn’t been difficult, talking about social change still is, he asserts.
I took the decision not to take any more flights right after the UN Climate Change Conference in Paris in 2015. It was an experiment to find out if an international career in science is feasible without flying – and I wrote two blog posts on this for the ETH Zukunftsblog. 2020 is now the fifth year of my endeavour. My conclusion remains the same: it is indeed possible to pursue an international career in science without (or almost without) flying.
