Decarbonisation was a word almost never spoken in shipping circles until three years and one month ago, when the International Maritime Organization agreed its Initial Strategy to halve carbon emissions by 2050 from 2008 levels.

The word made its first appearance in TradeWinds in December 2015 in a story headlined: “Shipping lobbies to keep IMO as driver of emissions regulations”. It appeared in just 27 articles from then until April 2018, when the IMO deal began to bring shipping into line with the Paris agreement on climate change.
