NZF Delay Risks Locking in Another Generation of Fossil-Fuelled Ships: WinGD
Engine manufacturer WinGD has highlighted the risk that delays to the IMO’s Net-Zero Framework (NZF) could lock in another generation of fossil-fuelled ships.
“Thanks to the adjourned vote in 2025, a whole generation of fossil-fuelled vessels will enter service at the same time as the Net Zero Framework was originally due to enter force in 2028,” Dominik Schneiter, CEO of WinGD, outlined in a LinkedIn post today.
He said further delays would make shipping's decarbonisation more expensive, requiring faster emissions cuts from existing vessels and newbuilds.
Despite industry climate targets, most new ships are still being ordered to run on conventional fuel oil or LNG, often in near-record numbers.
“Current ship ordering shows how, in the face of regulatory uncertainty, owners will rationally choose to maintain the status quo,” Schneiter said.
He called for clear rules on how alternative fuels would be treated under carbon pricing to guide investment by shipowners and fuel producers.
Schneiter said existing engine designs could use renewable versions of diesel, methane, ammonia, methanol, ethanol and LPG.
“What is needed now is the clarity on how those fuels will be treated under carbon pricing,” he said.
WinGD also called for clear rewards for zero- and near-zero-emission fuels and emissions accounting rules to help shipowners assess the costs of different fuel choices.
The IMO's Marine Environment Protection Committee is due to revisit the NZF in November, following the adjournment of its adoption process in 2025.
