As part of its commitment to addressing climate change, the IMO has been working on the development of a Carbon Intensity Indicator (CII) for international shipping. The CII is intended to measure the carbon efficiency of ships and assess their relative carbon emissions performance.
The concept of the CII was introduced in the IMO’s Initial Strategy on Reduction of GHG Emissions from Ships, adopted in 2018. The strategy sets out a vision to reduce total annual greenhouse gas emissions from international shipping.
The CII is being developed as a key tool to assess and monitor the carbon intensity of ships, providing a standardized and transparent measure for evaluating their energy efficiency and emissions performance. It is expected to be a dynamic indicator that can be updated periodically to reflect technological advancements and best practices.
The CII requirements will take effect from 2023, so in 2024 the industry is expecting to receive the first feedback of CII measure. The Royal Institution of Naval Architects is proposing the technical conference to gather key stakeholders of the maritime industry to discuss challenges and opportunities of this measure.
