The IMO adopts greenhouse gas reduction strategy

The IMO’s vision is to phase out greenhouse gas (GHG) emissions as soon as possible within the end of this century. The aim is to reduce total emissions from shipping by 50% in 2050, and to reduce the average carbon intensity by 40% in 2030 and 70% in 2050, compared to 2008.

TecReg - greenhouse gas reduction strategy

Relevant for ship owners and managers, shipyards, design offices, suppliers and flag states.

On 13 April 2018, the IMO adopted a strategy to reduce GHG emissions from shipping. The strategy is the first step of a roadmap adopted by the IMO to address GHG emissions in shipping.

Ambitious targets

The 50% emission reduction is ambitious, and will likely call for widespread uptake of zero-carbon fuels, in addition to other energy efficiency measures. These fuels are not available today, and there needs to be a consorted effort towards developing such fuels and making them available in the necessary quantity. At the same time, all other industries and nations are expected to contribute to reducing GHG emissions. This will both complement the efforts in the shipping industry, but at the same time there will be competition for the zero-carbon fuels.

Possible policy measures

The strategy contains a long list of possible measures that the IMO can implement, both regulatory measures and supporting measures. The IMO’s next step will be to prioritize and decide on which measures to follow up and to develop an action plan. 

Some of the measures under consideration are:

Short term (until 2023):

  • Review and strengthen EEDI, including new phases
  • Develop operational indicators
  • Speed reduction/optimization
  • National Action Plans (domestic measures, decided independently by countries)
  • Life cycle GHG/carbon intensity guidelines for fuels

Medium term (2023 to 2030):

  • New reduction mechanism, possibly including operational indicators
  • Market-based measures
  • Implementation programme for low-carbon fuels

Long term (2030 onwards):

  • Development and provision of zero-carbon fuels
  • Other innovative reduction mechanisms

Next steps

This is an initial strategy, and according to the roadmap there will a review in 5 years, based on the results from the Data Collection System and a 4th IMO GHG study to be undertaken in 2019. A programme for follow-up actions of the strategy will be discussed at the IMO in a working group meeting, likely in September, and at MEPC 73 in October, 2018.

Recommendations

This will not impact existing ships in the short term, but over time requirements are expected to apply for both new designs and existing ships. Ship owners and builders are recommended to monitor and explore energy efficiency and alternative low-carbon fuel options.

2020 Sulphur update - outcome of the MEPC 74

The 74th session of the Marine Environment Protection Committee (MEPC 74) was held at IMO in London on 13–17 May 2019. This was the last MEPC meeting before the 0.50% global sulphur limit takes effect on 1 January 2020, and the focus was on the implementation and completion of guidelines to help stakeholders prepare and ensure consistent implementation. We strongly recommend stakeholders to prepare in due course and update plans according to the latest IMO guidance. This statutory news contains a summary of sulphur-related resolutions and circulars adopted at MEPC 74.

Survey by remote inspection techniques - use of approved service suppliers

The use of remote inspection techniques (RIT) is increasing. Today, drones, climbers, or robot arms, can be used as an alternative to close-up surveys in both the DNV GL rules and IACS Unified Requirements. RIT may significantly reduce the survey time and costs, while improving the safety of surveyors and the owner’s personnel. From 1 January 2019, DNV GL has approved the use of service suppliers for RIT. This technical news explains how RIT can be used and how suppliers can achieve DNV GL approval.
