Iindustry made clear that efforts to signi? cantly lower the carbon footprint of shipping presented “biggest technol- ogy challenge in the past 100 years”.

This statement was not an exaggera- tion. In fact, the transition to a low- carbon future will take more than an un- precedented commitment to the research and development that traditionally un- derpins technological advance. Finding complex solutions that are at once com- mercially viable, technically feasible, sustainable and safe will require a stable regulatory environment that provides long-term certainty for a wide range of investors in new low-carbon technolo- gies.

The IMO last year set an ambitious course with its preliminary greenhouse- gas (GHG) strategy, which was aimed at reducing CO2 emissions by at least 40% per cargo tonne-mile by 2030 (pursuing a 70% reduction by 2050) and a 50% reduction in GHG emissions by 2050 (against 2008 levels).

According to the organization’s 3rd
