A new study by University Maritime Advisory Services ( UMAS ) and Energy Transitions Commission ( ETC ) prepared for the Global Maritime Forum for the Getting to Zero Coalition, estimates that the cumulative investment needed between 2030 and 2050 to halve shipping’s CO 2 emissions amounts to approximately $1-1.4 trillion—an average of $50 billion to $70 billion annually for 20 years. The report authors note that these figures should be viewed in the context of annual global investments in energy, which in 2018 alone amounted to US$1.85 trillion. The global shipping fleet accounts for ~2.2% of CO 2 emissions. 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 trillion to $1.9 trillion. The estimate of investments required is based on ammonia (NH 3 ) being the primary zero carbon fuel choice adopted […]
