The Environmental Ship Index (ESI) entered a new era in March, with the confirmation of an expanded suite of performance modules to support ports and vessel owners on the journey to decarbonisation and lowering emissions. Coming online in 2026, ESI’s revised and expanded offering will take into account a range of potential emissions, introduce a new GHG methodology, and reward innovation and application of zero-emissions techniques onboard vessels. The decision to revise and expand ESI’s modules and formulae, and the introduction of the new GHG and innovation modules, came as a result of major developments in global maritime environmental regulation, which the scheme encourages ships to exceed. The transition process to the new suite of ESI modules will take place through 2024 and 2025, with support from ESI’s Board and administrator, as well as IAPH, ensuring that ample support and time is available to facilitate a smooth migration for the scheme’s Incentive Receivers and Incentive Providers.
