A decade of mandatory energy efficiency measures for ships

More than ten years have passed since the International Maritime Organization (IMO) first defined binding international measures to improve the energy efficiency of ships aimed at reducing greenhouse gas (GHG) emissions. The package of measures combined with support for implementation has put maritime transport on the path to decarbonization.

During this period, the Sea Cargo Charter also joined in the issue of controlling air pollution from ships by establishing a framework to align charter activities with responsible environmental behavior.

How to measure a ship’s CO2 emissions?

Despite all the regulatory foundations laid in recent years and the upcoming revision of the 2023 GHG Strategy, there is still confusion in the industry as to how CO2 emissions are calculated before they can be reduced. Even with the massive adoption of low sulfur fuels and ship washers, the CO2 footprint of shipping is still high.

While owners and operators have the flexibility to reduce their emissions or pay to offset their carbon footprint, it is essential to be able to calculate the cost before they can make a decision. This is where the great void comes in – what methodology would you use? There is the Energy Efficiency Indicator (EEOI) using grams of CO2 per nautical ton-mile, and the Annual Efficiency Ratio (AER) using grams of CO2 per deadweight-ton-nautical mile. Then there is the question of who is actually responsible for the payment. Overall, it’s still unclear exactly who and how this will be affected.

A new calculator is online to help you

This is where AXSMarine says they can help. The pioneer in providing advanced solutions for shipping professionals recently released a new complementary addition to its portfolio – a calculator that can estimate the CO2 effect of each ship’s journey on the environment.

AXSMarine’s CO2 Calculator is a fully automated tool, which works with both EEOI and AER methodologies. It takes into account the carbon factors HSFO, VLSFO and LSMGO and provides an alignment delta to the EEOI trajectory values ​​for its users.

While the CO2 emissions calculations are fully automated and do not alter the workflow of its users, AXSMarine’s new tool also has the ability to estimate the specific CO2 costs of each trip, based on the region of operation.

AXSMarine CCO Steve Fletcher says that while the confusion created by unclear regulations can only be dispelled by the regulators themselves, it can also be resolved by releasing the instruments the industry needs to monitor its carbon footprint on the environment:

“AXSMarine’s new CO2 calculator is what the dry bulk industry has been waiting for to stay compliant with environmental regulations. It is just the latest of a number of steps we’ve taken to ensure professionals industry can monitor the impacts of their fleets on the environment.

Besides the full automation of our calculator, which will deliver new information without impacting the workflow of its users, it is also fully integrated into our product ecosystem. This turns the need to track CO2 emissions from its ships into just one more digit on the screen. “
