"The government" is a vague term.

I specifically referred to the Chinese, Russian and Indian governments.

The US government is doing much in the realm of being "green", but what this country does to clean up is more than cancelled out by the three countries I mentioned in particular.

A modern SUV pollutes less running on the highway at 75 MPH than a 1980 subcompact does sitting in place.

You also have to consider what being green/eco friendly really means.

One popular "feel good" way to lower pollutants you are producing is to get a hybrid. There's more pollution and energy use involved in the production of
a hybrid auto than you could ever save by using the hybrid. Batteries, special electrical components, etc. produce more pollutants than a normal vehicle will over a lifetime.

Electric cars? Again, sounds good, but where does the additional electricity come from? Also, back to the sticky issue of high density storage batteries.
