The International Maritime Organisation (IMO) has committed to achieving net-zero emissions by 2050. The goal was agreed upon by all 178 countries who are members of the IMO, with indicative targets of a 20-30% reduction in emissions from 2008 levels by 2030, and a 70-80% reduction by 2040. However, environmental groups have criticised the plan for being insufficient to restrict global temperature increase to 1.5C above pre-industrial levels, as set out in the Paris Agreement.
