New analysis puts a price tag on maritime shipping’s decarbonization
Shipping needs to make a radical shift to zero carbon energy sources in the coming three decades to reduce the sectors total greenhouse gas emissions by at least 50% of 2008 levels by 2050 – a target set by the International Maritime Organization, a UN agency responsible for regulating shipping. This transition requires significant infrastructure investments in new fuel production, supply chains, and a new or retrofitted fleet.
A new study by UMAS and the Energy Transitions Commission for the Getting to Zero Coalition spells out the scale of the challenge. Depending on the production method, the cumulative investment needed between 2030 and 2050 to halve shipping’s emissions amounts to approximately $1-1.4 trillion, or an average of $50-70 billion annually for 20 years. If shipping is to fully decarbonize by 2050, this will require further investments of some $400 billion over 20 years, bringing the total to $1.4-1.9 trillion.
