Book-and-claim methodology decouples the CO2e savings from the initial service generating the savings. In turn, the savings can be allocated to any shipment carried by ONE for customers who choose ONE LEAF+.

As per the United Nations' Intergovernmental Panel on Climate Change (IPCC), CO2e is the measure of the global warming impact of different greenhouse gases, with CO2 as the common baseline of reference. Hence, CO2e is more comprehensive than CO2 taking into account all global warming gases instead of only CO2. 
 
Under the Well-to-Wake methodology, ONE will account for the warming effect of all significant global warming gases (for eg CH4, NO2, SO2)

Scope 3 emissions refer to indirect emissions arising from a company's value chain. It covers 15 categories upstream and downstream. A company's scope 3 emission is your valuechain supplier scope 1 and 2 emissions.

It is a separate premium and not a surcharge. For biofuel, recognising the volatility of the feedstock market, the premium for ONE LEAF+ is tied to the market basis of UCOME B100 and is subject to change. Please contact your local sales representative for more information.

ONE LEAF+ is available for all container types/trade lanes subject to the supply availability of our biofuel choice. 

To calculate our customer’s existing emissions, ONE employs the industry-standard Clean Cargo Working Group methodology managed by Smart Freight Centre.

Under ONE LEAF+, CO2e savings are calculated by subtracting the well-to-wake CO2e emissions of our use of biofuel under ONE LEAF+ from that of conventional fuel. The CO2e savings, verified by 3rd-party verifier, are allocated to our customers who choose ONE LEAF+ to reduce their estimated emissions. 

Customers that purchase ONE LEAF+ will receive a certificate (see image) certifying the volume of CO2e savings on an annual basis (any additional requirements subject to negotiation).

ONE’s selection criteria for biofuel is to employ only Used Cooking Oil Methyl Ester (UCOME) feedstock, which generates about 84% less well-to-wake CO2e emissions considering B100 compared to Very Low Sulfur Fuel Oil (VLSFO). UCOME is a second-generation biofuel made from used cooking oil which satisfies the definition of waste or residue under EU RED. UCOME is a type of Fatty Acid Methyl Ester (FAME), which follows more stringent criteria.

Biofuel is the first alternative fuel available under ONE LEAF+. ONE has placed an order for 12 Methanol Dual-Fuelled boxships which will be delivered in 2027 and continues exploring further emission reduction solutions.
