People don't use energy because it's sexy, they use it because they need or want things that cost energy and they pay according to their need.
The concern is not importing carbon, the concern is countries using the energy themselves. For every Tesla there's a thousand little diesel trucks driving around on the african continent, and that number will only go up, especially if western demand for oil goes down.
I don't think the 'attractiveness' of decarbonization has any consequence at all. Just look at Texas, one of the most oil dependent, climate change denying anti-green states there is, yet they're also the largest producer of renewable wind energy, and are closing their coal plants. That's got nothing to do with attractiveness, it's just economics. Selling wind power is simply profitable.
Vice versa, no one cares more about the planet than the rich people of the world. You won't find more green movement startups, solar panels on roofs, high efficiency buildings, electric cars and even vegetarians in any other slice of the population. Yet those same nature lovers are also the ones who do the most international flights. With each round trip burning as much fuel as a regular person would in a year of commuting to work. It's got nothing to do with attractiveness, they want to, there's no other way, they can afford to, so they do it.
