It is beyond doubt at all that we are faced with a climate emergency. In order to respond effectively, we need concrete measures, fast. Among other types, pollution caused by air travel is considerable and we have to think about viable alternatives.
One such alternative is a train network, possibly subsidised by governments. It could be either a network of sleeper trains or something more comprehensive, depending on the means available and feasibility. There are already useful governmental initiatives in Germany and Sweden, which are most welcome. There are also Europe-wide political initiatives, so far unfortunately without a wider impact.
It goes without saying that such initiatives should become truly global, the sooner the better.
We believe that this is a welcome step forward in probably the biggest long-term crisis that we are facing. It is a matter which must be considered urgently.
