India remains heavily underdeveloped domestically. And the cultural gap - most remarkably, India's enormous vegetarian community - plays a bigger role than it's economic model in curbing gross emissions.

It should also be noted that India has had and continues to have one of the largest active Communist Parties in history. In fact, the 34 years of the Left Front rule in West Bengal is the longest-serving democratically elected communist-led government in the world.

So you can't really use India as a pure capitalist counterexample, unless you only want to discuss the corners of the county under decisive BJP rule (itself a relatively new political turn for India).
