Passenger Transport CO_2 Emission and Mitigation Policies in developing Mega-city: A Case Study of Shanghai

摘要

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 CO_2 emission in passenger transport sector, and integrated policies framework should also be built. In this study, CO_2 emission of Shanghai's passenger transport from 2002 to 2008 is estimated. The total CO_2 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.
