The related Food and produce miles is a big thing according to friends in the UK. How far does your food have to travel before reaching your plate? That would seem to work against NZ freight exports. However presumably it is not such a big thing for the current Conservative government as they have policies that will put up more barriers to trading with the EU, which is their largest and closest supplier of produce.
Yep it is becoming a big thing, wine, meat etc will eventually suffer.
In terms of tourists there already quite a few in the more enlightened countries (Scandinavia, Netherlands etc) that are swearing off air travel. Might just be a fad with all the GretaThunberg brigade, or it might become a proper thing.
