This is pretty common amongst most people, not just climbers, not just flying. The explanation I've heard is that no one wants to be the only one giving up something when others are clearly not. For one individual actions won't make much difference and secondly it seems a bit pointless and unfair to do so when no one else is. Action really needs to come from governments. There are various schemes suggested, like a personal carbon allowance, but politicians are pretty much in bed with the worst polluting industries so don't want to do anything that might upset them.
> Foreign trips are nice. Putting tax on fuel will not reduce the amount of air travel. It will simply price out a few people.
If it prices out some people then surely that amounts to fewer flights. The higher the tax the more people are priced out. Other forms of transport will then be more able to compete with aviation.
