German bulker owner Oldendorff Carriers has added its name to the growing Getting to Zero Coalition.
This is an alliance of more than 100 like-minded companies and organisations within the maritime sphere, supported by key governments, it said.
Members commit to decarbonising shipping and meeting IMO targets.
It was launched at the United Nations Climate Action Summit in New York on 23 September, when it had 70 members.
The first target is to reduce shipping’s greenhouse gas (GHG) emissions by at least 50% by 2050.
"The coalition is committed to getting commercially viable deep sea zero emission vessels into operation by 2030," Oldendorff said.
Getting to Zero is a partnership between the Global Maritime Forum, the Friends of Ocean Action and the World Economic Forum.
The UCL Energy Institute, Environmental Defence Fund, Sustainable Shipping Initiative and the Energy Transitions Commission will support the work.
"Following the recent COP25 Climate Change Conference in Madrid, Oldendorff Carriers recognises the urgency to stop climate change," it added.
"We will continue to investigate non-GHG causing methods of energy and propulsion for ships. Over 95% of the Oldendorff fleet, and most of our chartered vessels, are eco-type vessels."
Last month, it signed a research agreement with the Massachusetts Institute of Technology’s (MIT) Center for Bits and Atoms (CBA), which will investigate "disruptive improvements" in ship design and propulsion.
The initial emphasis will be directed at improving hydrodynamic efficiency, which builds on work CBA has been doing with the aerospace and automotive industries.
