What is it about?

Greenhouse gases (GHG) emissions from the logistics sector were investigated using Hong Kong as an example. The data including cargo freight between Hong Kong and other places by different transport modes (i.e. aircraft, container ships, trucks, and trains) for the period of 2007–2012 were collected and GHG emissions were estimated.

Why is it important?

International transport is crucial to the development of world trade and the logistics sector contributes to a country’s gross domestic product. This paper is one of the first papers investigating GHG emissions from the logistics sector in one of the world's trading hubs.


The total cargo throughput via Hong Kong was 299,522 kilotonnes in 2012 while GHG emission amounted to 35,834 kilotonnes of CO2-eq. due to freight services in the same year. The results of scenario analysis showed that the amount of GHG emissions could be reduced at about 100 kilotonnes of CO2-eq. per 100 kilotonnes of cargo by switching a portion of air cargo movements to and from mainland China to land freight (rail freight preferable) or sea freight.
