I wasn't particularly thinking of NZ, and I don't have any figures to back it up for NZ, but I think it's fairly well established that wealthy Westernised countries use more energy per capita than poor countries. e.g. https://en.wikipedia.org/wiki/List_of_countries_by_energy_consumption_per_capita
And intuitively it feels right to me for within NZ. We live in an energy economy; the cost of *everything* is dependent to a large extent on the energy involved in producing it. If a person owns more or consumes more goods, then they're using more energy. A poor person simply doesn't go on overseas trips, for example. Or even travel much around NZ. And we do have extremely wealthy individuals who fly around the country and internationally in their own bizjets, at a vastly greater energy cost per person. A wealthy person accumulates possessions of various kinds, all of which take energy to manufacture and distribute. A wealthy person has a better diet, a larger house which costs more energy to heat and cool, a newer car (or cars), etc.
So I'm interested now in why it doesn't feel true to you.
I was thinking more quantitatively than in principle, and I was looking at it from an NZ perspective. Eg, if the top 1% wealthiest people in NZ took a lifestyle dip to say the 5 top percentile level, would that really have a noticeable impact on NZ's emission profile? My suspicion is "no", but I'd be interested to see some stats if they were available.
I'm not using this as an excuse or justification for doing nothing, I was just curious to know whether your assertion had any factual backing.
Presumably if we as a country were really serious about this, we could stop inward tourism by air travel and limit outbound air travel to one per person per year (maybe making the outbound visa a tradeable commodity). But I don't think anyone is quite that serious about it yet (hence my first post in this topic).
Personally, to answer the original question, I'm taking NZ holidays in preference to overseas ones, have switched to a more economical car and have switched to LED lighting at home. Will probably replace the second family car with an EV within the next six months.
