I already thought about remote conferences last year and it seems like it’s becoming a reality with all those canceled conferences now only taking place online. Although it is not for environmental reasons (but rather to protect people), it may show some organizers that remote conferences are perhaps not such a bad alternative. It just needs to be technically well implemented and it will take a few less flights.
Climate change is reaching the media more and more, every day we hear more stories about the bad things caused by climate change and also the youth protests “Fridays for Future” are very popular (at least here in Germany and Europe). That is one side to it.
On the other hand, I read on Twitter almost every day about conferences and developers all over the world who fly there just to listen to some presentations or give some themselves.
