Emission reduction, and especially greenhouse gas (GHG) reduction, is the challenge of the century.
Decarbonisation usually refers to the overall process of reducing “carbon intensity.” This means that the amount of greenhouse gas emissions is decreased. The ways to achieve this include increasing energy efficiency, replacing fossil fuels with low carbon alternatives or carbon emission abatement.
Decarbonisation has become a global imperative and a priority for governments, companies, and societies because it plays a key role in limiting global warming.
The marine sector must contribute significantly to fighting climate change, and decarbonisation is the way.
The best ways to reduce emissions in shipping are different for existing fleets and for newbuild vessels.
Decarbonisation in shipping means that the shipping industry needs to transform into a form of green transport. The International Maritime Organization (IMO) has put regulations in place to drive this transformation. The IMO’s Initial Greenhouse Gas Strategy has three interlinked ambitions:
It is expected that the IMO will revise this Initial Strategy in 2023 to put the sector on a 1.5ºC compatible pathway.
Newbuild ships must meet the requirements set in the Energy Efficiency Design Index (EEDI). The result is that new ships will be increasingly energy efficient.
Now, existing ships must also meet certain requirements, set by the Energy Efficiency existing ship Index (EEXI).
More information on complying with EEXI: this article explains how to speed up decarbonisation without slowing down vessels.
In addition, vessel fleets worldwide must adapt and comply with the new Carbon Intensity Indicator (CII). The IMO has set this measure for operational efficiency, and it comes into effect in 2023.
The CII requires consideration from ship owners and operators. Ships get their CII rating every year, and the rating ranges from A (best performance) to E.
If a ship is rated E for one year or D for three years in a row, the owner/operator must submit a plan to correct the situation. The plan must outline how the ship will achieve a C rating or better.
Do you need expert advice on complying with 2023 maritime regulations? This article on maritime regulations and opportunities explains why upgrading to comply represents a chance to secure long-term competitiveness and profitability.
If any of your vessels are in danger of falling into D or E categories, you need to make positive changes to improve their ratings – and fast.

Decarbonisation and net zero emissions are important. The good news is that shipping can be more sustainable without sacrificing business success.
Vessel fleets must now comply with the new CII ratings. Thousands of ships need to start operating more efficiently – or there is a clear risk that they will become stranded assets. Knowing when and how to adapt will be critical for maximising business and ensuring that the vessels can stay in circulation.
If you own or operate ships that must reduce emissions and improve fuel consumption, you have several options, including

Another option to consider is a lifecycle agreement with an expert partner such as Wärtsilä. In addition to a maintenance agreement, the partnership can include outcome-based business models. In practice, you would get a guarantee that your vessel would achieve a suitable CII rating in the agreed schedule.

Decarbonisation will take more than technology. It is important that every actor in the shipping industry connects, collaborates, and shares their knowledge.
To power shipping in the future, Wärtsilä is investigating a wide range of fuels and developing engines that produce less and less greenhouse gas emissions. Five fuel types are particularly interesting for the shipping industry:
