Who said anything about the majority? And that's certainly not the demographic of HN, or the people creating most of the carbon footprint.
Also, by advanced economy standards, most of the world is deep in poverty.
> majority don’t have the luxury to go for the more expensive option because of their love of the environment.
It's not luxury and love, but necessity, responsibility, and survival. The impovrished people will suffer the most. Also, the options aren't necessarily more expensive, and are generally much cheaper if you account for the costs of climate change.
