Strong sustainability can only work if we’re willing to downshift our economy and lifestyles. “Less is more” should be the new credo and one part of it should be a more responsible way of travelling.
When I travelled by plane during the last years it was either for work or social reasons like weddings. The social expectations will be the hardest to deal with if I won’t fly at all anymore, while my career is my own choice. Flying to conferences all over the world and presenting my work on sufficiency-based lifestyles doesn’t go together very well, so there has to be another way of making a meaningful contribution in academics while sticking with my own ideals and beliefs.
