Perhaps considering something that people seem to love almost as much as oversize vehicles - that is, paving things in and building ugly buildings out of concrete - Italian researchers have developed a catalytic cement. Called TX Active, the material contains a titanium dioxide mix that catalyzes CO, NOx, and other pollutants into less dangerous compounds. In one test, use of the material in street paving apparently produced a 60 percent (!!!!) reduction in local NOx levels. Assuming costs are not prohibitive, this would be a fantastic thing to start seeing all over the place.
