Do we want cleaner cars

Concerns about environmental pollution linked to transport activity raise the question on how we can reduce emissions from private cars. Considerable research efforts have been devoted to the development of cleaner fuels and car technologies, which seem to have some environmental potential. The aim of this paper is to make an assessment of the environmental and welfare impact of a shift from conventional to alternative vehicle technologies.
