To provide an updated global emissions inventory for 2016–2023 using advanced methodologies to support the IMO’s strategy of achieving net-zero GHG emissions in international shipping by 2050, with interim targets for 2030 and 2040, and to evaluate emission trends including the growing impact of methane from LNG-fueled ships and black carbon to inform future decarbonization policies and strategies.
Fuel Type: e-fuel
Life cycle assessment of e-/bio- methanol and e-/grey-/blue-ammonia for maritime transport
to provide an independent and comparative assessment of key alternative fuels for the maritime sector, and to evaluate their energy efficiency, greenhouse gas (GHG) reduction potential, production scalability, maturity, and economic competitiveness, in both the short and long term
The cost of capital challenge in delivering a just and equitable transition for shipping
To examine the financial barriers to a just and equitable transition to zero-emission fuels in the shipping sector, this report focuses on the cost of capital as a critical determinant of project feasibility. It compares the levelised costs and investment risks of green ammonia (e-ammonia) production across regions, including both developed and developing countries, to illustrate how disparities in capital access affect global competitiveness. Furthermore, it explores policy instruments—such as grants and concessional finance—that can mitigate investment challenges in low-income countries, thereby supporting the IMO’s objective of a fair transition while enabling the widespread adoption of renewable marine fuels.
Synthetic fuels for shipping
To explores the potential of synthetic fuels, specifically e-methanol, e-methane, and e-diesel, as viable alternatives for shipping decarbonization.
To evaluates their production technologies, sustainability, availability, economic feasibility, and regulatory challenges.
How the IMO’s mid-term measures might shape shipping’s energy choices and transition to e-fuels
To examine how the IMO’s mid-term measures will influence shipping’s transition to e-fuels and decarbonization.
To evaluate different policy scenarios, including fuel standards, levies, and financial incentives, to determine their effectiveness in promoting low-emission fuel adoption.
Regulatory trends and impact: Second Edition
To provide the explanation of the latest adopted and anticipated IMO regulations, offering insights into their impact on the maritime sector.
To highlight key regulatory changes at regional and national levels, emphasizing their potential implications for industry stakeholders.
Maritime Forecast to 2050
To emphasize the necessity of improving energy efficiency and establishing fuel transition strategies to achieve the decarbonization targets of IMO. This report explores methods to maintain the competitiveness of international shipping by 2030, focusing on fuel reduction, digitalization, and carbon capture technologies. Additionally, it examines strategies for expanding related infrastructure and addressing cost increases, providing insights into strategic responses to these challenges.
Availability of E-fuels and E-fuel-capable Vessels from 2027–2030
To assess the market readiness of e-fuels and e-fuel-capable vessels for commercial deployment in the maritime sector between 2027 and 2030. The report seeks to provide insights into the production capacity of e-fuels, the readiness of vessels to use these fuels, and the alignment of these elements to support ZEMBA’s next tender process. The study also aims to identify challenges such as financial barriers and deployment mismatches, offering strategies to accelerate zero-emission technology adoption in shipping.
Preparing Tanker Vessels for Conversion to Green Fuels
To analyse the technical, economic, and environmental impacts of converting tanker vessels to green fuels such as methanol and ammonia. This report aims to assess the readiness level and costs of fuel transition, providing insights to propose optimal design and operational strategies that align with sustainable shipping practices and regulatory requirements.
Exploring the technical feasibility of carbon capture onboard ships
To assess the technical feasibility of implementing carbon capture systems on ships to help reduce CO2 emissions, particularly concentrating on both retrofit and newbuild vessels.
