I try not to use the car unless I have no choice. Fortunately we have a good bus service, in the city and a metro as well. Most of the time I use public transport unless I’m going to the grandchildren. Currently my daughter and I are trying out a car share. I use it in the week and she has it at the weekend. It’s working well at the moment but it’s early days.
Unfortunately the cost of a train journey and return to my daughter at the other end of the country is prohibitive. Even coaches cost more and additionally take over 8 hours so just now I take a plane, much to my chagrin. I do catch public transport to the airport and on the way back if it’s not too late.
I travelled on the trains daily as a child and later in my earlier years. I would prefer to go by train but as I said, the cost is enormous.
Even worse, long distance annually at the moment to New Zealand to see the rest of my family. It takes me all year to save and my family do usually contribute.
I’d like to see train tickets reduced, not much chance of that!
Sooner or later I’m sure governments will impose more tax on travelling by plane. At that point I’ll consider the coach.
I agree that freight should be taken by train as it always was in the past and that would need far more infrastructure, just as there used to be with goods yards, new tracks etc.
To answer OP, I do think about my carbon footprint and have tried to minimise use of plastics, recycling, repurposing, change of diet.
