Let’s not pretend anymore.
The uncomfortable truth is that that people in affluent countries don’t want to change their lifestyle. Affluent countries are less affected by global warming than countries responsible for a fraction of global emissions. All the emissions from manufacturing follow suit.
It also includes social pressure, try to have a kid and no car, people will look at you like you are crazy. I even live in a country with great public transportation.
As a nomad, can confirm. Coming back to America, the scale and quality of materials is remarkable.
It's not primarily a lifestyle issue, and the problem is no longer primarily developed countries. Per-capita carbon emissions in developed countries have decreased 30% in the past 20 years, and energy demand has remained relatively constant, in fact decreasing slightly in some places due to increases in efficiency. Meanwhile, developing countries like China and India are projected to account for 35-40% of total global emissions in the next decade, far outweighing the impact of individual lifestyle choices in the West.
Of course, people should do everything they can to reduce or offset their own emissions. But the solution is going to have to be societal, keeping up with energy demand by adding more nuclear, solar, and wind to the grid.
