Shipping could fall short of its goal to cut carbon emissions in half by 2050, analysis by classification society ABS suggests.

The IMO has challenged the industry to reduce its carbon intensity, chopping carbon per tonne of cargo carried by 40% by 2030 and 70% by 2050, compared to 2008 levels.

ABS’s projections, outlined in its report Setting the Course to Low Carbon Shipping, is set to meet those goals through a reduction in the use of conventional fuel oil and increased use of alternatives such as LNG, LPG, methanol, biofuels, ammonia and hydrogen.
