When we look at the per capita numbers, we see that indeed the west has higher numbers compared to countries such as India and China, with higher populations. However, when we look at yearly CO2 emmissions, we notice a very different story.
Asia in it's entirely is pushing out 22 Billion ton of CO2 each year. China is the big reason for that, with over 11B Ton, together with India, nearing 3B Ton. It must be noted that these figures must be taken with a grain of salt, seeing how China tends to manipulate figures, so it most likely is higher.
Compared to Europe, that has 5B Ton each year. Or to Northern America (including US), which has just over 2B ton.
Added to that, world wide there is almost 1B Ton each year for shipping and aviation.
But when we look at those numbers, We see Asia having an extreme large portion of the combined amount. A big reason for this is, offcourse industry. A lot of our products get made in those regions. Another one is over population. India has over 1.4B people, compared to 334 million in the US. Even if the per capita number is lower in India, it's total statistic will always be higher, because they have a lot more people.
Keep in mind, it's not just the people, but also the industry there to produce enough products to keep the country going. Electricity, food production, clothes, ...
It's easy to blame the west based on those per capita numbers, but reality is that the big change has to come from those regions. Population controls, more control on working environments, ... . And especially, start producing more products in the own countries, it would cut back on transportation polution. Yes, that will drive up the price of a lot of products. But it would make a lot more sense going that way, than banning cars.
See, I can actually be a nice person sometimes. I hope you got something from all of this.
