The richest countries are the biggest polluters per capita, no competition. Accusing the "Indians and Chinese" for pollution which is in fact the direct consequence of "Western" consumption is misleading, hypocritical and redirects attention from the real, underlying problems.

No argument at all about per capita energy consumption. My point isn't to blame developing countries at all. It's to illustrate that as over 2 billion people try to emulate Western lifestyles, their energy consumption is going to skyrocket. And Western expectations that they should just limit their growth/advancement is the hypocritical view.
When you view Western energy consumption, it's growth is largely correlated to population increases.
