Aderco has formally launched 2055G+, a programme that combines the company’s 2055G marine fuel additive with emissions monitoring, data verification and Gold Standard carbon credit issuance. The initiative targets ship operators, managers and charterers navigating compliance with the IMO Carbon Intensity Indicator (CII) and the EU Emissions Trading System (EU ETS).
Based on data from more than 100 vessels already enrolled, fuel savings through the 2055G additive range from 2% to 5%. Two results have been independently verified by classification societies: ABS confirmed 4.84% savings on a reefer vessel and RINA confirmed 3.25% on a Capesize bulk carrier. The company treats some 40 billion litres of fuel annually and has been active in additive development for over 45 years.
At the heart of the programme is the 2055G additive itself — marketed as 100% vegetal organic, ashless and metal-free — intended to improve combustion efficiency, disperse sludge, stabilise fuel and reduce exhaust emissions. Vessels enter a minimum six-month trial phase during which a consumption and emissions baseline is established from historical noon reports. The resulting performance data then feeds into a carbon credit workflow managed in partnership with Adi Terra, a project developer specialising in carbon and biodiversity credits.
Each verified tonne of CO₂ avoided generates one Voluntary Carbon Credit under the Gold Standard Retrofit Measure Improving Efficiency Methodology. These credits can be resold commercially or applied to demonstrate environmental compliance. Esteve Servajean, Head of Marine at Aderco, described the programme as “a bridge between the 2055G technology, data and monetisation” allowing operators to go beyond pledges and show verifiable action. Gérald Baiwir, Head of Environment, said the programme aims to “remove the guesswork from green accreditation”.
