It has been suggested that ecological damage is being done by excessive academic travel. Students and academics are among the most frequent flyers, they thus significantly contribute to climate change. This is in part a response to the increasingly globalised nature of research in recent decades.

In addition, the expectation that researchers attend international conferences has grown exponentially. What steps can we take to decrease our impact?
