CO2 Emissions Statistics for the World Commercial Fleet

Research output: Contribution to conferencePaperResearchpeer-review


Carbon dioxide (CO2) emissions from commercial shipping are currently unregulated, but nevertheless they are a subject of intense scrutiny by the world shipping community. According to the Kyoto protocol, definite measures to reduce CO2 emissions are necessary in order to curb the projected growth of greenhouse gases (GHG) worldwide. Shipping has thus far escaped being included in the Kyoto global emissions reduction target for CO2 and other GHGs, but it is clear that the time of non-regulation is rapidly approaching its end, and measures to curb future CO2 growth are being sought with a high sense of urgency. Various analyses of many aspects of the problem have been and are being carried out and a spectrum of measures are being contemplated. It is clear that a reliable emissions inventory is essential for both scientists and policy-makers in order to formulate and evaluate the implementation of relevant regulations. To contribute to this debate and possibly complement other studies onthe subject, the authors of this paper have conducted their own analysis on emissions of the world fleet database and can herein present some preliminary results of the emissions statistics of the following major ship types: bulk carriers, crude oil tankers, container vessels, product/chemical carriers, LNG carriers, LPG carriers, reefer vessels, Ro-Ro vessels and general cargo ships. A separate analysis was carried out for small vessels under 400 GRTand for passenger vessels.
