ESI: A Trusted Tool for Sustainability in the Shipping Industry

In the realm of sustainability and operations management within the shipping industry, the challenge of reducing emissions and decarbonizing is paramount. The multitude of options available can be overwhelming for managers seeking to make informed decisions. One established solution that port and shipping professionals can rely on is the Environmental Ship Index (ESI), a global standard created in 2011 by ports in collaboration with the International Association of Ports and Harbors (IAPH). With over 60 ports and maritime administrations worldwide using ESI to incentivize environmental performance improvements on more than 6,000 vessels, including half of the world’s container fleet, it has become a trusted tool in the industry.

Recognized by the International Maritime Organization (IMO) in 2023, ESI is evolving to meet the changing landscape of global maritime environmental regulation. The revised and expanded offering of ESI will consider a broader range of emissions, introduce a new GHG methodology, and reward innovation in zero-emissions techniques on vessels. This development aligns with the industry’s focus on exceeding regulatory standards and embracing sustainable practices to combat climate change.

ESI’s voluntary and automated environmental-scoring system for ships provides incentives for lower port dues and other benefits for vessels that surpass current emission standards. The system is designed for simplicity and effectiveness, with participating ports able to set their own qualifying levels and incentives. As ESI continues to adapt to meet the decarbonization challenge, it remains a valuable tool for industry stakeholders committed to reducing emissions and protecting the environment.
