With the Greenhouse Gas Strategy towards 2050, the IMO has set the goal to reduce carbon intensity by 40% within the next decade up to 2030 and by 50% in total (70% intensity) up to 2050. The Greenhouse Gas Strategy was approved by the IMO in 2018. The reduction rates are related to the baseline of 2008. Short-term, mid-term and long-term measures are distinguished to achieve the goal.
Short-term measures are meant to be set into force by 2023. Different measures were considered and widely discussed, for example the introduction of a speed limit. With the experience of market-driven slow steaming for nearly one decade, this measure is promising with regards to its potential to save CO2Â emissions.
