It’s not to say individuals can’t do anything collective action works in most any aspect of life. What the concern becomes is the fact the major populous needs to forgo so much just to make up for the activities of a few people too special to stand in line with the rest.

A recent study here puts private flight as being somewhere around 10X more emissions costly in a per-person basis globally based on and more than 1000X less efficient that train travel where it available on the same distance. That just counting personal flight which may have some buisiness existing, though many could be forgone and done by a web confrence save for the ‘drinks amd golf’ aspect to those meetings, but large pleasure boats and non-comercial space flights are pure luxury expendatures that the world could do without. Still the larger populous is told we need to cut back while such things continues on.
