A common argument in favor of building sprawl-generating roads and highways is that if we just pave over enough of the United States, we can actually reduce pollution and greenhouse gas emissions by reducing congestion.  For example, a Reason Foundation press release cited a report by two University of California/Riverside engineering professors, “Real-World CO2 Impact of Traffic Congestion” (available online at ).    But if you read the report carefully, its policy impact is a bit more ambiguous.
