The Science Based Target Initiative, a partnership between Carbon Disclosure Project (CDP), the United Nations Global Compact (UNGC), World Resources Institute (WRI) and the World Wide Fund (WWF), has launched the SBTi maritime tool. The sector specific tool is the first initiative that provides corporations operating, associated with, or using services from the shipping sector with a concrete way of benchmarking their activity against a 1.5°C target that can guide their short, medium and long term actions.
The SBTi tools provide corporations with an approach that can enable and clearly communicate their adoption of a strategy unambiguously aligned with the science from Intergovernmental Panel on Climate Change. The SBTi guidance and tools enable the recommendations from the High Level Expert Group on the Net Zero Emissions Commitments of Non-State Entities, released at Sharm el-Sheikh during COP27, which suggest that goals and net-zero alignment should be independently verified by third parties, which includes SBTi among others, to avoid ‘net-zero greenwashing’.
Adopting the SBTi targets enables long-term strategy and planning that can protect corporations against the risks of asset-stranding and technology-obsolescence that can arise from policy ambition that ratchets up over time (incremental target setting).
Dr Jean-Marc Bonello, Principal Consultant at UMAS, UCL Energy Institute’s maritime consultancy wing, provided the technical input to the SBTi maritime tool. He said:
While the rate at which the carbon intensity of maritime transport needs to decline can feel daunting, this is what the science is dictating. Initiatives such as SBTi are providing a tool for companies to assess their performance and plan ahead to mitigate against costly changes to their operations too far down the line.
By including upstream emissions and all GHG emission species, the SBTi for maritime tool captures all the impact of the combustion of maritime fuels and the use of energy to operate ships. The tool is based on the IPCC’s Special Report “Global warming of 1.5°C” the most recognised and authoritative source of information on the scale of GHG reductions needed. That makes the SBTi tools the most ambitious sector-specific target in contrast to the levels of ambition in the IMO Initial Strategy, which aims for a minimum of 50% GHG reduction by 2050 on 2008 levels. Whilst ambition in the IMO’s strategy may increase through the strategy’s revisions, reliance on multilateral regulation alone is not sufficient for guiding and communicating a strategy that contributes to avoiding dangerous climate change.
Shipping’s decarbonisation can be achieved by both improving energy efficiency and substituting the oil-derived fuels the sector currently uses e.g. with electricity and hydrogen-derived fuels. Whilst many of the technologies to achieve this are mature, new energy supply chains based on low and zero GHG emission hydrogen are still scaling up. The shipping trajectories in the tool therefore take into consideration the rate of diffusion of new technologies and scalable zero emission fuels by basing the trajectory on a S-curve similar to the approach taken by the Getting to Zero Coalition. This means that carbon intensity reduction rates are slower for this decade, as new fuels and technologies emerge, but accelerate sharply in the 2030s, as those technologies scale up, to achieve decarbonisation by the first half of the 2040s.
Many corporations, for example through coZEV (Cargo Owners for Zero Emission Vessels), which includes major retailers such as Amazon and IKEA, have set long-term targets for their maritime freight to be zero emissions by 2040. The new SBTi targets will allow them to benchmark their progress in the short and medium term, including actions that maximise energy efficiency and transparently reporting on their progress against the trajectories

For more information a webinar will be hosted Tuesday 6 December 2022 3:30 - 4:30pm GMT.
Learn about the SBTi Guidance for the Maritime Transport Sector, and how businesses in this industry can set robust emissions reduction targets in line with climate science to accelerate their decarbonization efforts at the depth and pace needed to enable a 1.5°C future.
