You have to look at the whole picture, not just what is coming out the exhaust pipe that instant.

Whole picture includes many details.
Non-plugin hybrids generally come out ahead over their life time. The fuel saved, and less brake work to a small degree, and what gets reused or recycled, will cover the extra environmental cost that want into their manufacturer.
In regards to plugins, just moving the emissions out of the city can mean a big health and quality of life improvement for residents, even if the power generator is dirty. It is easier to monitor, regulate, and clean up emissions from a few central, sationary sources than from thousands of tiny, mobile ones.
Electricity can also be made cleaner and increase the renewables percentage over time. With a non-plugin, the ICE and emission equipment wears over time, getting dirtier. Then renewable fuels are still a tiny portion, and then needed gasoline and diesel will come increasingly more costly, energy intensive, and dirtier sources.
Then there are the national security advantages in the US's case of switching from a foreign energy source to domestic ones. Look what effect the Saudis have had on world oil prices in order to hurt political and economic rivals. Tar sands and shale oil are the economic ones. Shale oil exploration is stopping because of the ow cost of crude, and the current wells will only last 18 months or so.
