The new frugality has let sustainability become more firmly established in our everyday lives – doing good as a side effect, if you will. All over Europe, people are turning to second-hand goods and changing their travel habits: although climate protection is not always the main reason for avoiding air travel, we are still flying less than we were before the pandemic.

New behaviours like these may have a chance of bringing about a long-term change in attitude. In fact, many of us have now begun to really understand what environmentalists have long been proclaiming: there is no planet B – and the more people join in, the more we can achieve.
