providing digital solutions for a carbon-free maritime industry

Optimise your CO2 exposure commercially with zero44.

The problem


This number is expected to rise by 20% in the coming years. New ship technology and fuels are needed - but they need 10 more years to develop. Once ready it will still take decades to replace the world fleet with the new ships.

C02 challenge

The shipping industry is hugely challenged to manage the new CO2 costs

Decades or today

New technologies and fuels are needed - and fleet replacement will take decades

Cost increase

Carbon intensity ratings will cause significant costs starting January 2023

Up to 20%

Emissions from global shipping will grow by 20% until 2050


International Maritime Organisation

Starting January 2023, shipping companies will see their ships being rated in an A to E scheme based on their CO2 emissions in a calendar year. D and E ratings will require corrective actions to reduce CO2 emissions. These actions will have an impact on the ship’s commercial operations. More info on IMOs work to cut GHG emissions from ships.

European Union

The shipping industry will become subject to the EU Emission Trading System (ETS), which requires shipping companies to surrender allowances for 40% of verified emissions for 2024; 70% for 2025; and 100% for 2026 and beyond. As part of the ETS, all emissions emitted by vessels calling at an EU port for voyages within the EU, as well as 50% of emissions from voyages that start or end outside the EU, and all emissions at berth in EU ports, will be included. In EU waters, this will increase ship voyage costs significantly. More info on the EU strategy to reduce emissions from the shipping sector.

Poseidon principles

In June 2019 11 leading banks joined forced to commit to the so-called “Poseidon Principles”: a set of 4 principles that provide guidance on what it means to be a responsible bank in the maritime sector. Today, 27 banks have signed the agreement and take their financing decisions accordingly. In December 2021 seven large marine insurance companies adopted their version of the Poseidon Principles. More info on the Poseidon Principles.

Getting to Zero coalition

The Getting to Zero Coalition is an alliance of more than 150 companies within the maritime, energy, infrastructure and finance sectors, supported by key governments and IGOs. The Coalition is committed to getting commercially viable deep sea zero emission vessels powered by zero emission fuels into operation by 2030. More info on the Getting to Zero Coalition.


EU Emission Trading System
& Carbon intensity indicator

IMO CII and the extension of EU ETS to include maritime transport poses major challenges for shipowners, charterers and operators. zero44’s all-in-one solution optimizes your EU ETS and CII exposure on auto-pilot.

We guide you through every step required to ensure full compliance, monitor your CO2 exposure, and provide AI-enabled commercial optimization. In addition, you will be brought as close to the auctions and secondary market for EUA emission certificates as possible.


We provide customised digital solutions for shipowners, charterers, and operators.

  • Carbon monitoring and reporting based on the ship's daily data
  • Smart commercial voyage planning to reduce CO2 emissions
  • Trusted data to agree on which charter party will bear the CO2 costs

Flexible data input

We use your existing data sources for the daily vessel data. No hardware or specific software required.

Data quality control

We will control data quality by using algorithmic plausibility checks, external data sources and machine learning.

Modular frontend design

We will calculate actionable projections and simulations visualised in ways that fit our clients' needs.
