CO2 Emission Statistics for the World Commercial Fleet

The purpose of this paper is to present an analysis of carbon dioxide (CO2) emissions of the world commercial fleet. The analysis is based on the Lloyds-Fairplay world ship database for 2007 and produces various 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 is carried out for small vessels under 400 GRT and for passenger vessels. The main outputs from this analysis for each ship type-size bracket are the emitted grams of CO2 per tonne-km and an estimate of the total CO2 produced in a year. The methodology for estimating these statistics is described, and a comparison with other studies is made.
