I strongly support the Bush Administration's clean diesel rules, which will reduce air pollution from diesel engines by more than 90 percent, and reduce the sulfur content of diesel fuel by more than 95 percent.

Love is in the air but the air is highly polluted

The health effects of air pollution imperil human lives. This fact is well-documented.

Rhode Island works hard to reduce air pollution in our communities. We passed laws to prohibit cars and buses from idling their engines and to retrofit school buses with diesel pollution controls. But there is only so much a single state can do, particularly against out-of-state pollution.

I spend a year at the Hoover Institute at Stanford, researching market approaches to air pollution control.

Carpooling is important for urban density, air pollution and other reasons, but carpooling is not the kind of thing that actually changes the energy equation.
