 Agency (“ EPA”) or the states where we operate, compliance with these regulations could entail significant capital expenditures or otherwise increase the costs of our operations.

The amended Annex VI also established new tiers of stringent nitrogen oxide emissions standards for marine diesel engines, depending on their date of installation. Tier III NOx standards were designed for the control of NOx produced by vessels and apply to ships that operate in the North American and U. S. Caribbean Sea ECAs with marine diesel engines installed and constructed on or after January 1, 2016. Tier III requirements could apply to additional areas designated for Tier III NOx in the future. At MEPC 70 and MEPC 71, the MEPC approved the North Sea and Baltic Sea as ECAs for nitrogen oxide for ships built on or after January 1, 2021. The EPA promulgated equivalent (and in some senses stricter) emissions standards in 2010. As a result of these designations or similar future designations, we may be required to incur additional operating or other costs.

At MEPC 70, Regulation 22A of MARPOL Annex VI became effective as of March 1, 2018 and requires ships above 5,000 gross tonnage to collect and report annual data on fuel oil consumption to an IMO database, with the first year of data collection having commenced on January 1, 2019. The IMO used such data as part of its initial roadmap (through 2023) for developing its strategy to reduce greenhouse gas emissions from ships, as discussed further below.

As of January 1, 2013, MARPOL made mandatory certain measures relating to energy efficiency for ships. All ships are now required to develop and implement Ship Energy Efficiency Management Plans (“ SEEMP”), and new ships must be designed in compliance with minimum energy efficiency levels per capacity mile as defined by the Energy Efficiency Design Index (“ EEDI”). Under these measures, by 2025, all new ships built will be 30% more energy efficient than those built in 2014.

MEPC 75 adopted amendments to MARPOL Annex VI which brought forward the effective date of the EEDI’s “phase 3” requirements from January 1, 2025 to April 1, 2022 for several ship types, including gas carriers, general cargo ships, and LNG carriers.

Additionally, in 2022, MEPC amended Annex VI to impose new regulations to reduce greenhouse gas emissions from ships. These amendments introduced requirements to assess and measure the
