Reducing Shipping Emissions Through Innovation and Collaboration

The International Maritime Organization (IMO) plays a critical role in global efforts to combat climate change by addressing greenhouse gas (GHG) emissions from the shipping industry. Aligned with the United Nations Sustainable Development Goal 13 and the 2015 Paris Agreement, the IMO’s mission is to reduce GHG emissions that contribute to global warming. This blog explores the IMO’s ongoing initiatives, achievements, and plans to mitigate emissions from international shipping, driving the transition to a sustainable and low-carbon future.
A Decade of Regulatory Action: Energy Efficiency Measures
On July 15, 2011, the IMO implemented the first-ever international mandatory measures aimed at improving the energy efficiency of ships. These measures set the foundation for a series of additional regulatory steps. Notably, the Initial IMO GHG Strategy was adopted in 2018, providing a framework to reduce GHG emissions and promote energy-efficient shipping practices.
In 2023, the IMO revised its GHG Strategy, setting ambitious new targets and reinforcing its commitment to curbing emissions. To facilitate these measures, the IMO has developed a robust capacity-building and technical assistance program, supported by global projects to ensure effective implementation.
The 2023 IMO Strategy on GHG Reduction
The 2023 IMO Strategy on the Reduction of GHG Emissions from Ships marked a significant milestone. Adopted during the Marine Environment Protection Committee’s (MEPC) 80th session, the strategy set an enhanced target of achieving net-zero GHG emissions by 2050. Key objectives include:
-
Carbon Intensity Reduction: A 40% reduction in the carbon intensity of international shipping by 2030.
-
Adoption of Alternative Fuels: Ensuring that zero or near-zero GHG emission fuels represent at least 5%, striving for 10%, of energy used by international shipping by 2030.
-
Mid-term Goals: Achieving at least a 20% reduction in GHG emissions by 2030 (striving for 30%) and a 70% reduction by 2040 (striving for 80%).
These targets reflect the urgency of transitioning the shipping industry towards sustainable energy solutions.
Developing and Implementing Mid-term Measures
The 2023 strategy introduces a basket of mid-term measures designed to accelerate emission reductions. These measures include:
-
Technical Elements: A marine fuel standard aimed at reducing the GHG intensity of marine fuels over time.
-
Economic Elements: A GHG emissions pricing mechanism to incentivize the adoption of low-carbon technologies and practices.
A comprehensive impact assessment has been conducted to evaluate the potential effects of these measures on the global fleet and member states. The strategy aims to foster a just and equitable transition, ensuring no disproportionate burden on developing nations.
Timeline for Mid-term Measures
The timeline for implementing these measures is as follows:
-
April 2025 (MEPC 83): Approval of mid-term measures.
-
October 2025: Adoption of the measures at an extraordinary MEPC session.
-
2027: Entry into force, following a 16-month preparatory period.
The adoption of these measures will provide a regulatory framework to guide the shipping industry’s energy transition.
Support for Developing Countries
Recognizing the unique challenges faced by Least Developed Countries (LDCs) and Small Island Developing States (SIDS), the IMO’s strategy includes targeted capacity-building programs. These initiatives, funded by member states, aim to provide technical and financial assistance, enabling these nations to participate in and benefit from the global energy transition.
Tracking Progress and Future Reviews
The 2023 IMO Strategy will undergo a review in 2028, ensuring its alignment with emerging technological advancements and global climate goals. This iterative approach allows for adjustments to maintain the strategy’s relevance and effectiveness.
Mandatory Energy Efficiency Requirements
Under the framework established by the 2018 Initial Strategy, ships are required to enhance their energy efficiency. Key measures include:
-
Energy Efficiency Existing Ship Index (EEXI): Mandated since January 1, 2023, this index evaluates a ship’s design efficiency.
-
Carbon Intensity Indicator (CII): Ships are assessed annually and receive ratings from A (best) to E (worst) based on operational carbon intensity.
Ships with low ratings are encouraged to adopt practices such as hull cleaning, speed optimization, and the use of renewable energy sources to improve efficiency.
Alternative Fuels: Pioneering the Energy Transition
Decarbonizing the shipping industry necessitates a shift to low- and zero-carbon fuels. Promising alternatives include ammonia, biofuels, hydrogen, methanol, and wind-assisted propulsion. However, these options come with challenges such as safety concerns, infrastructure requirements, and lifecycle emissions.
The IMO has adopted Guidelines on the Lifecycle GHG Intensity of Marine Fuels, evaluating emissions from production to end-use. Ongoing research and pilot projects are exploring the feasibility of these fuels, with a focus on addressing barriers to adoption.
Future Fuels and Technology Project
In collaboration with the Republic of Korea, the IMO’s “Future Fuels and Technology” project investigates global trends in low-carbon marine technologies and fuels. The project’s objectives include:
-
Identifying incentives and regulatory mechanisms to promote the adoption of sustainable fuels.
-
Addressing safety and training requirements to ensure smooth implementation.
Global Collaboration and IMO’s Role in COP Events
The IMO actively participates in the United Nations Framework Convention on Climate Change (UNFCCC) Conferences of the Parties (COP) to align maritime policies with broader climate goals. By engaging with stakeholders and fostering international collaboration, the IMO strengthens its capacity to address global challenges.
The Road Ahead
The IMO’s commitment to reducing GHG emissions is a cornerstone of global efforts to combat climate change. With the adoption of the 2023 GHG Strategy and the introduction of mid-term measures, the shipping industry is on a clear path toward decarbonization. By prioritizing innovation, collaboration, and capacity-building, the IMO continues to lead the way in promoting sustainable and resilient maritime practices.
As the world moves closer to the 2050 net-zero target, the IMO’s initiatives will remain pivotal in shaping a cleaner and more sustainable future for international shipping. By fostering partnerships and leveraging technological advancements, the organization underscores its role as a global leader in environmental stewardship.
