About the Southampton Marine and Maritime Institute (SMMI):
The SMMI is a community of academics from across the University of Southampton, whose interests and research are linked to the marine/maritime realm. It is an internationally recognised multi-disciplinary centre of excellence for research, innovation and education spanning both the marine and maritime sectors. Read more here.
What further action is needed by […] the International Maritime Organization to drive emissions reductions? What can the UK Government do to drive international action on emissions?
a) From a legal perspective, climate justice is achieved through the implementation of the principle of CDR. Although the principle is not yet recognised as a norm of customary international law, it has already been incorporated in numerous international instruments, including the United Nations Framework Convention on Climate Change (UNFCCC). The principle in its UNFCCC form entails that “the Parties should protect the climate system […] on the basis of equity and in accordance with their common but differentiated responsibilities and respective capabilities”. Thus, it nuances the efforts from states with varying national circumstances to solve environmental problems of a global nature on the basis of two criteria: responsibility (for causing the environmental problem – both historical and present); and capability (to tackle the problem – both financial and technical). Importantly, not only is the principle incorporated in several IMO documents (e.g. the London Convention), the IMO’s GHG Strategy also recognises the need to be “cognizant of the principles enshrined in instruments already developed, such as […] the principle of common but differentiated responsibilities and respective capabilities, in the light of different national circumstances”. Focusing on the design and operation of climate mitigating measures proposed to/by the IMO, the GHG Strategy provided that their impacts “should be assessed and taken into account as appropriate before adoption of the measure[s]”, and added that “particular attention should be paid to the needs of developing countries, especially small island developing states (SIDS) and least developed countries (LDCs)”. In practice, this assessment has been difficult to conduct, as demonstrated in the experience of the technical and operational measures to improve the energy efficiency of ships, the scope of which were expanded during the MEPC’s 76th session. According a United Nations Conference on Trade and Development’s (UNCTAD) report (July 2021), the impact assessments conducted were inaccurate and highlighted important challenges, including the existence of many uncertainties and variables due to the limited availability of data. Recognising these limitations, the MEPC adopted the measures while agreeing to keep under review their potential impacts on the most vulnerable states in order to make adjustments where necessary. A similar approach to MBM is very unlikely as implications on SIDS, LDCs and developing States would be more substantial. Hence, the MEPC agreed to formally address them but deferred the discussion to its next session (22 to 26 November 2021).
b) From a policy perspective, the universal agenda embodied in the United Nations (UN) Sustainable Development Goals (SDGs) requires member states to adopt an integrated and indivisible approach to tackling the SDGs and their 169 associated targets in order to achieve “inclusive, people-centred and sustainable development with no one left behind”. This entails that prospective MBM adopted by the IMO towards achieving SDG 13 (Climate Action) should at least not contravene SDG 1 (No Poverty) and SDG 10 (Reduced Inequalities).
a) Fill important knowledge gaps through investing and leading in research and development around ship design/efficiency, green fuels and technologies, safe handling, port infrastructure, CCUS; and continue to investigate how remote operation and autonomy optimisation of uncrewed or lean-crewed vessels can reduce environmental impacts.
b) Continue to support zero emission feasibility and demonstration projects to push forward the transition to zero emission fuels for the shipping industry and urgently move ahead with the deployment of carbon capture and storage (CCS) at scale, including shipping of CO2 from orphan-industrial clusters with no regional geostorage.
c) Update its laws and regulations to accommodate the energy transition (including the transport of CO2, Renewable Transport Fuel Obligation obligations, HM Maritime Coastguard Agency’s codes of practice, Emission Trading System and carbon pricing), and develop forward-looking and coherent policies for an over-abundance of renewable energy, green hydrogen production, and energy storage.
