This paper proposes a second-best approach to cutting CO2 emissions caused by the urban mobility of passengers. We develop policy scenarios that compare the first-best tool of carbon tax, to a combination of second-best tools, not originally aimed at reducing CO2 (i.e. congestion charging,...

Low CO2 emitting urban infrastructure projects are expected to play an important role in mitigating climate change. By enabling projects to sell their CO2 emission reductions on the international carbon market, the Clean Development Mechanism (CDM) turns the positive environmental benefits of...
