car emissions consist of hydrocarbons, nox, carbon monoxide, and
carbon dioxide. A lot of the emissions occur when the engine is in a
transitional state or not running at optimal efficiency. With a
parallel battery power, hybrids can keep engines running at optimal
efficiency (or off). Hybrids produce less emissions than simply the
difference in mpg.

A gallon of gasoline burned in a Civic or a Hybrid still puts
22 pounds of carbon dioxide in the air. Its just the Hybrid
goes 40% further per gallon.

It's true that the realistic mpg of Prius is about 45 mpg, which is only about 30% better than the 35 mpg I get from my gasoline Civic. But I think most people neglect the emissions benefit of hybrids: typically 90% less than gasoline cars. And probably way more than that compared to a Hummer.
