The growing concern of shippers on the carbon footprint of their supply chains has led to the development of various environmental indices that enable the measurement of the transport supplier environmental performance. This paper is focusing on the environmental performance indices that have been developed for the shipping industry and enable the measurement and comparison of the environmental performance of individual vessels. Two environmental indices for shipping – the Environmental Ship Index (ESI) and the Clean Shipping Index (CSI) - are analyzed in this paper highlighting their particular features and giving some evidence of their practical implementation. The scope of this paper is to investigate the usefulness of these indices for shippers and freight suppliers’ decisions and identify their effectiveness for the improvement of the environmental performance of shipping services. According to our findings, both indices are comprehensible and transparent. The credibility of the CSI is quite larger compared to the ESI, due to third party verification that is performed by various classification societies. The CSI also has a more holistic approach, consisting of a network of members built up from a broad range of maritime stakeholders in contrast to the ESI that is restricted to shipping companies and ports. The ESI is the most commonly used index for the provision of economic incentives by ports, which is an expected outcome, as this index was developed by the International Association of Ports and Harbors (IAPH, which is formed by the ports themselves in their efforts to improve their environmental performance. The environmental differentiated port fees offered by Port Metro Vancouver and Port of Gothenburg on the basis of the vessels’ ESI and CSI scoring were investigated. The fact that, in both ports, the number of vessels that have an ESI score or a CSI Class is constantly growing, suggests that eco-labelling initiatives and the use of environmental performance indices is becoming more and more popular in the shipping industry. Apart from the shipping companies that might choose a port that rewards ‘cleaner’ vessels, the shippers themselves may require employed vessels to have such an ecolabel to demonstrate their commitment to sustainable transport. Given the growing concern of shippers on the environmental performance of their supply chains, this paper suggests that these indices are useful tools for the evaluation and measurement of the transport supplier environmental performance and could be employed by shippers and freight suppliers for their transport mode choice decisions.
