Passenger transport CO2 emission and mitigation policies in developing mega-city: A case study of Shanghai

Economic growth and rising demand of mobility in developing mega-city are leading to the increase of car ownership, and consequent emission increases. Reliable methodology is needed to estimate CO₂ emission in passenger transport sector, and integrated policies framework should also be built. In this study, CO₂ emission of Shanghai´s passenger transport from 2002 to 2008 is estimated. The total CO₂ emission increases constantly from 2002 to 2008, and the increase is mainly attributed to the increase of private car transport; but the passenger transport emission intensity (emission divided by GDP) decreases from 2002 to 2008. To achieve low-carbon transport in mega-cities, an integrated policy framework is introduced. Analysis shows that, integrated policies are needed to achieve this goal.
