Port of Açu to implement Environmental Ship Index as of 2021

Commencing in 2021, the Port of Açu will implement the Environmental Ship Index (ESI), which rates vessels that exceed the emission standards established by the International Maritime Organization (IMO).

Ships that perform better than required by the current environmental standards, including greenhouse gas emission levels, will have access to preferential port tariffs. The ESI project is headed by the World Ports Sustainability Program (WPSP), created by the International Association of Ports and Harbors (IAPH).

“We have world-class port infrastructure and capacity to welcome the largest ships in the world. By adopting the Environmental Ship Index, we make it clear that Açu is committed to participating in the global effort to reduce emissions,” explains José Firmo, CEO of Porto do Açu Operações.

The Environmental Ship Index (ESI) identifies seagoing ships that perform better in reducing air emissions than required by the current emission standards of the International Maritime Organization. The ESI evaluates the amount of nitrogen oxide (NOX), sulphur oxide (SOX) that is released by a ship and includes a reporting scheme on the greenhouse gas emission of the ship. The ESI is a good indication of the environmental performance of ocean-going vessels and will assist in identifying cleaner ships in a general way. All stakeholders in maritime transport can use the ESI as a means to improve their environmental performance and as an instrument to reach their sustainability goals. With over 8,000  registered vessels, ESI has become the standard tool used by the world’s ports to reward and incentivise shipowners meeting and exceeding IMO emissions standards.
