- WinGD becomes the first engine designer to join MAMII, strengthening efforts to cut methane emissions from LNG-fuelled ships.
- Methane slip reduction is progressing, with WinGD lowering emissions from 1.7% a decade ago to under 0.8% today, targeting 0.5%.
- Collaboration beyond engine design — including measurement, certification, and regulation — is seen as key to solving methane emissions at scale.
Engine developer WinGD has joined the Methane Abatement in Maritime Innovation Initiative (MAMII), becoming the first engine manufacturer to partner with the cross-sector coalition. MAMII was established to address methane emissions from LNG-fuelled shipping, which remain a critical challenge despite LNG’s potential as a lower-emission alternative fuel.
As a leader in LNG-based marine engines and power systems, WinGD brings technical expertise and valuable operational data to the group. This addition will help the coalition better evaluate practical applications of methane abatement technologies across the maritime industry, according to Clean Shipping International.
Tackling Methane Slip
Methane, the primary component of LNG, offers emissions advantages compared with conventional fuels — but only if methane slip (unburned methane escaping into the atmosphere) is effectively controlled.
MAMII Chair Panos Mitrou noted that WinGD’s participation provides “deeper visibility into how an engine manufacturer achieves continuous improvement.” He emphasized that the partnership aims to make methane slip “a problem of the past.”
WinGD’s Progress in Emission Reduction
WinGD CEO Dominik Schneiter highlighted that engine performance has advanced rapidly, with methane slip from WinGD engines falling from 1.7% of gas volume ten years ago to less than 0.8% today. The company is targeting levels below 0.5%.
However, Schneiter stressed that tackling methane requires more than engineering solutions. Broader progress is needed in measurement standards, certification frameworks, and regulatory structures to ensure meaningful reductions across the industry. By joining MAMII, WinGD is signalling its commitment to collective action at what Schneiter called a “pivotal moment” for shipping’s energy transition.
Industry Collaboration and Next Steps
WinGD also took part in technical sessions during the first “MAMII Day” in June 2025, where industry leaders and EU officials shared data, explored retrofit options, and discussed how voluntary industry initiatives could shape future regulation.
The inclusion of an engine manufacturer like WinGD marks a significant step for MAMII, expanding the coalition’s expertise and momentum as the industry works to scale proven solutions and influence policy development.
