"Nobody", really?

As a bare minimum, many people can choose to take more environmentally friendly vacations. You don't have to go on a cruise, and yet that's a booming industry. You don't have to fly across an ocean. Almost everybody who does these things has the option to go on perfectly fine, perhaps even better, less carbon intensive alternative vacations.

And yes, there are people who consciously make that lifestyle change. Not enough, of course. But only a Sith deals in absolutes.

You guys are naive. Sure, it's possible, but most people don't do this, don't want to do this and will not do this. And of those that DO some of these things, a large subset probably does it in a ineffective way that OP so nicely illustrated in the phone/1 extra km by car example.

No, the solution must be technical while people are allowed to maintain most of the comfort they are used to. Anything else and you will simply not be able to convince people to do so even if that means burning the world down.

This is one those cases of "why not both"?

I totally agree that we need technical solutions. We have no hope without them. But it's also naive to think that endless growth without lifestyle changes is possible.

That said, if you really think about it, the most important lifestyle change of all is happening, and quite dramatically so: People are having fewer children.

This is problematic though, isn't it?

It's effectively mass subsidization for bad behavior at the expense of people who are altruistic. I don't see how it can be a winning strategy in the long run.

For just a second, let's set aside our hopes and idealism, because I do realize how distasteful this world view may be.

If the best hope for the environment is that altruistic people suffer a disadvantage so that everyone (including defectors who don't want to help anyone and only help themselves) can win, how is that not a strong long term advantage for anti-social behavior?

"Great, don't take that plane ride, stop burning fossil fuels. More for me until we run out! I can even afford to have more kids because I don't care how impactful they are, while you responsibly go extinct."

Feels like a losing battle, and not a fun way to lose either. I suspect that we all know, despite our hopes, that eight billion people will not decide to collectively give up their own happiness for the betterment of billions of strangers they aren't related to.
