Aderco Launches 2055G+ Program for Verified Emissions Reduction

Aderco links fuel treatment performance to carbon credits in new maritime programme

Aderco has launched 2055G+, a maritime programme designed to convert fuel-treatment performance data into verified emissions reductions and subsequently into Gold Standard carbon credits. The company positions this as both a decarbonisation tool and a commercial opportunity for ship operators working with conventional marine fuels. The programme targets vessels facing compliance and reporting obligations under IMO CII and EU ETS regulations.

The platform combines fuel additive technology with monitoring systems. Consequently, emissions claims rest on verifiable operational data rather than projections alone. Aderco states that the process moves from fuel efficiency gains through measured CO₂ reductions to certified credits. These credits can then be sold or applied to reduce a vessel’s carbon footprint.

More than 100 ships have already entered the programme according to Aderco. Fuel savings range from 2% to 5% based on performance data the company has collected. Verified examples include an ABS-referenced reefer vessel achieving 4.84% savings and a RINA-referenced capesize vessel recording 3.25% savings. The programme is scheduled to launch fully in 2026.

How the programme converts efficiency gains into certified credits

The 2055G+ system operates by capturing real-time fuel consumption and emissions data from vessels using Aderco’s fuel treatment technology. This data feeds into a monitoring framework that measures actual CO₂ reductions against baseline performance. The company then submits these verified reductions for certification under the Gold Standard, an internationally recognised carbon credit standard.

Gold Standard certification requires robust measurement, reporting and verification processes. Therefore, the programme includes third-party validation of emissions data. Classification societies such as ABS and RINA have referenced specific vessel performance under the system. This external verification is central to the programme’s credibility in carbon markets.

Once certified, the carbon credits represent verified tonnes of CO₂ reduced through improved fuel efficiency. Ship operators can sell these credits on voluntary carbon markets or retain them to offset their own emissions reporting. The dual outcome addresses both regulatory compliance needs and potential revenue generation.

Esteve Servajean, Aderco’s Head of Marine, described the tool as creating a bridge between technology, data and monetisation. He added that it helps operators and charterers go beyond pledges and demonstrate measurable progress toward sustainability commitments. This positions the programme as a response to increasing scrutiny of corporate environmental claims in the shipping sector.

IMO CII and EU ETS requirements drive demand for verified data

Shipping companies face mounting pressure from two major regulatory frameworks. The International Maritime Organization’s Carbon Intensity Indicator came into force in 2023. It rates vessels from A to E based on their carbon efficiency. Ships receiving D or E ratings for three consecutive years must submit corrective action plans. Poor CII ratings can affect charter rates, insurance premiums and port access in some jurisdictions.

Meanwhile, the European Union Emissions Trading System expanded to include maritime transport from January 2024. Ships calling at EU ports must now surrender emissions allowances for CO₂ released during voyages. The system covers 100% of emissions within EU waters and 50% of emissions from international voyages departing from or arriving at EU ports. Compliance costs are significant, particularly for operators running older vessels on conventional fuels.

Both frameworks require accurate emissions data. However, measuring actual fuel efficiency improvements versus theoretical baselines remains challenging. Many fuel-saving technologies quote estimated performance gains. Translating those estimates into auditable emissions reductions acceptable to regulators or carbon credit certifiers requires robust data collection and independent verification.

This is where Aderco’s programme enters the picture. By linking fuel treatment performance directly to verified emissions data, the system provides operators with documentation that satisfies both regulatory reporting and carbon credit certification requirements. The operational data can support CII rating improvements. Simultaneously, the certified credits offer a financial return that can offset compliance costs under EU ETS.

Financial and operational considerations for vessel operators

Fuel represents the largest operating cost for most shipping companies. Therefore, even modest efficiency gains translate into substantial savings over time. A 3% reduction in fuel consumption on a vessel burning 50 tonnes per day saves approximately 1.5 tonnes daily. Over a year, this amounts to roughly 550 tonnes of fuel at current marine fuel prices of around £400 per tonne. Annual savings would therefore approach £220,000 per vessel.

Carbon credits add a second revenue stream. Prices in voluntary carbon markets vary considerably. However, Gold Standard credits typically trade between £10 and £30 per tonne of CO₂. A vessel achieving 3% fuel savings might reduce emissions by approximately 1,700 tonnes of CO₂ annually. At £20 per tonne, certified credits could generate an additional £34,000 in annual revenue or offset value.

EU ETS allowances currently trade around £60 per tonne. Consequently, reducing reportable emissions under the scheme delivers direct cost savings. A vessel operating primarily on EU routes would avoid approximately £102,000 in annual allowance costs through the same 1,700-tonne reduction. The financial case strengthens considerably when fuel savings, carbon credit revenue and avoided EU ETS costs combine.

Upfront costs remain a consideration. Fuel treatment programmes typically involve initial setup fees, ongoing additive costs and monitoring equipment installation. Operators need to assess payback periods against their specific routes, fuel consumption rates and commercial structures. Charterers may share efficiency savings under some contracts, complicating cost-benefit calculations. Nevertheless, the combination of regulatory pressure and financial returns is making verified efficiency programmes more attractive across the sector.

Key programme details for shipping companies

• The programme launches commercially in 2026 and targets vessels using conventional marine fuels including heavy fuel oil and marine gas oil.
• More than 100 ships have entered the programme during its development phase, with reported fuel savings ranging from 2% to 5% depending on vessel type and operating profile.
• Verified performance data includes an ABS-referenced reefer vessel achieving 4.84% fuel savings and a RINA-referenced capesize bulk carrier recording 3.25% savings.
• Emissions reductions are certified under the Gold Standard, an internationally recognised framework for carbon credits in voluntary markets.
• The system provides data suitable for IMO CII reporting and EU ETS compliance documentation alongside carbon credit generation.
• Ship operators can choose to sell certified credits on voluntary carbon markets or apply them against their own emissions reporting obligations.
• Third-party validation from classification societies forms part of the verification process for emissions data submitted for credit certification.

What this means for decarbonisation pathways in shipping

The shipping industry faces a fundamental challenge. Alternative fuels such as methanol, ammonia and hydrogen remain expensive and require new bunkering infrastructure that barely exists today. Meanwhile, the global fleet continues to run predominantly on conventional marine fuels. Regulations are tightening faster than the fuel transition is progressing.

Efficiency improvements therefore represent the most immediately available decarbonisation tool for the existing fleet. However, proving those improvements to a standard acceptable for carbon accounting has been difficult. Many efficiency technologies rely on estimated savings that cannot be independently verified. This creates problems for companies making public commitments to reduce emissions or seeking to participate in carbon markets.

Programmes like 2055G+ attempt to close this verification gap. By combining operational technology with structured data collection and third-party validation, they convert efficiency gains into certified reductions. This matters particularly for charterers facing pressure from cargo owners and investors to demonstrate measurable environmental progress. A verified carbon credit represents tangible evidence of emissions reduction in a way that estimated savings cannot.

The broader implication is that operational efficiency may become a tradable asset. Ship operators who invest in proven fuel-saving technologies can potentially monetise those investments through carbon markets. This creates a financial incentive beyond fuel cost savings alone. For companies evaluating whether to adopt efficiency measures, the addition of credit revenue improves the business case.

There are limits to what efficiency alone can achieve. Even significant percentage gains in fuel consumption do not put the shipping industry on a pathway to absolute zero emissions. Alternative fuels and propulsion systems will eventually be necessary. However, efficiency measures buy time, reduce costs and generate verifiable progress while the industry develops longer-term solutions. Verified efficiency programmes therefore serve as a practical interim step in a multi-decade transition.

Where to find additional information on maritime emissions regulations

The International Maritime Organization publishes detailed guidance on the Carbon Intensity Indicator and related greenhouse gas regulations through its official website. Operators can find the latest CII calculation methodologies, rating thresholds and reporting requirements in the organisation’s marine environment protection committee documents.

Information on the European Union Emissions Trading System’s maritime provisions is available through the European Commission’s climate action directorate. The Commission provides regulatory texts, compliance guidance and updated emissions factors for shipping fuels. Additionally, the UK government maintains guidance on maritime emissions reporting requirements for vessels calling at UK ports following similar principles to EU ETS.

The Gold Standard Foundation offers comprehensive documentation on its certification standards for carbon credits. This includes methodologies for calculating emissions reductions, verification requirements and registry procedures. Ship operators considering carbon credit programmes should review these standards alongside their existing emissions monitoring systems.

Classification societies including ABS, RINA, Lloyd’s Register and DNV publish technical guidance on fuel efficiency technologies and emissions measurement systems. These resources help operators understand verification requirements and select monitoring equipment appropriate for their vessels. Furthermore, specialist support for emissions reporting and regulatory compliance can assist companies in navigating the documentation requirements across multiple jurisdictions.
