Using satellite data to calculate carbon footprint in the shipping industry

The ICCT has showed interest in improving our ability to assess ships' carbon footprint. Therefore, ITCC teamed up with researchers at the University of College London on a novel way around those limitations using the Satellite Automatic Identification System (S-AIS). S-AIS is a tracking system used to identify and locate vessels. The IMO International Convention for the Safety of Life at Sea, passed in the aftermath of the sinking of the Titanic, now requires that every ship larger than 300 gross tons be equipped with an S-AIS transponder that transmits ship identification, speed, and location every few seconds. This almost continuous stream of data enables researchers to calculate ship speed and therefore CO2 emissions with greater resolution and confidence. The data also offer an improved picture of shipping routes across the globe. The initial results of this research indicate that ship speeds are substantially lower than previously thought and that in-use ship efficiency varied greatly even within individual ship types. Ship movement in August 2011, as recorded by the Satellite Automatic Identification System (S-AIS). The velocity of the dots in the video reflects ship speed. The onboard S-AIS transponder electronically transmitted ship information, location, and speed to satellite, which monitors and tracks ship locations ...

Georgia Ports Authority recognized for its environmental efforts

The Georgia Ports Authority has won recognition by the Environmental Protection Agency as a leader in reducing carbon emissions. The Southeast Diesel Collaborative (SEDC), a public-private partnership formed by the U.S. EPA Region 4 office, named the GPA as a Community Leadership Award winner. "The GPA has voluntarily undertaken many projects to decrease diesel fuel consumption, resulting in improved air quality," said GPA Executive Director Curtis Foltz. "Some of those projects include our innovative eRTGs or electric rubber tired gantry cranes, the repower of diesel RTGs with variable alternators, and the retrofit of 11 switch locomotives by GPA's partner, Rail Link." In December 2012, the Georgia Ports Authority unveiled its first four electrified rubber-tired gantry cranes. The GPA board recently approved spending $8 million for Phase II of the eRTG project, which will convert 10 additional diesel RTGs to electric power, and install conductor rails at 12 more container blocks. GPA's transition to an eRTG fleet should be complete by 2024. Foltz said greater attention paid to environmental stewardship pays off in financial savings and improved efficiency. "Cutting diesel consumption means not only cleaner air, but also lower energy costs," he said. "Better cross-terminal truck transit means less idling and ...
