Verra has launched VM0053 Alternative Low-Carbon Fuels for Shipping, the first independent carbon accounting methodology designed to quantify and verify emissions reductions from alternative marine fuels such as green ammonia, hydrogen and e-fuels. The framework aims to unlock carbon finance for low-carbon shipping fuels and support the maritime industry’s decarbonisation efforts.
Washington | June 16, 2026 – Verra has introduced a new carbon accounting methodology designed to accelerate the adoption of alternative low-carbon fuels in the maritime sector, providing shipowners and fuel producers with a structured framework to quantify and verify greenhouse gas (GHG) emission reductions from cleaner marine fuels.
The methodology, VM0053 Alternative Low-Carbon Fuels for Shipping v1.0, has been released under Verra’s Verified Carbon Standard (VCS) Program and is being described as the first independent accounting framework specifically developed for emissions reductions achieved through the use of low-carbon fuels in shipping.
Addressing a Key Gap in Maritime Decarbonisation
The new methodology aims to bridge a longstanding gap in maritime carbon markets by establishing standardized rules for measuring and verifying emission reductions generated when alternative fuels replace conventional fossil marine fuels.
According to Verra, VM0053 applies to project activities involving fuels such as:
- Hydrogen produced through water electrolysis
- Green ammonia
- E-methanol
- E-diesel
- E-LNG
- E-LPG
- Other electro-fuels (e-fuels)
The methodology can be used for both newbuild and existing vessels, regardless of size, operating in territorial waters or on international voyages across the high seas.
Supporting Investment in Alternative Marine Fuels
Maritime shipping accounts for more than 80% of global freight transport and remains one of the most difficult sectors to decarbonise due to its heavy reliance on fossil fuels and the high cost of emerging alternatives.
Verra said the methodology is intended to help unlock additional financing for low-carbon fuels by creating a pathway for generating verified carbon credits linked to emissions reductions. The resulting carbon revenue could help offset the significant cost premium associated with e-fuels and other low-carbon marine energy solutions.
The framework also supports the use of drop-in fuels that can be used in existing vessel engines, allowing shipowners to reduce emissions without requiring major fleet replacement or extensive engine modifications.
Facilitating Value Chain Emissions Reductions
Beyond supporting vessel operators, Verra believes the methodology can provide a credible mechanism for companies across maritime supply chains to source, verify and scale reductions in value chain emissions.
As pressure grows from regulators, cargo owners and investors for greater emissions transparency, the methodology could become an important tool for demonstrating verified emissions reductions associated with cleaner shipping operations.
Industry Collaboration Behind Development
VM0053 was developed through a collaboration between Japanese shipping company Iino Kaiun Kaisha, Ltd., climate consultancy Grütter Consulting, and Verra.
The methodology underwent a public consultation process in 2024 as part of Verra’s standard methodology development framework before receiving final approval and publication.
Growing Momentum for Maritime Carbon Markets
The launch comes as the global shipping industry faces increasing pressure to meet decarbonisation targets set by the International Maritime Organization (IMO), while fuel producers continue investing in alternative fuels including green methanol, green ammonia, hydrogen and synthetic e-fuels.
By providing a recognized framework for quantifying and verifying emissions reductions from these fuels, Verra’s new methodology could help stimulate investment and support broader adoption of low-carbon fuel solutions across the maritime sector.
