Countries like US and Canada are much more polluting that India and China. The per capita emission in India is about 15 times less than of US and Canada. While everyone drives a car and enjoys all comforts of life in US, about 1 lakh villages in India don't even have electricity and most Indians use public transport for commutation. US and Canada should commit to reduce the emission levels before they could ask India and China to commit. How many people in US would commit to use public transport to save the environment? India cannot stop its development for a better environment.
