If you were developing an A-Z of ways to ­tackle shipping’s carbon emissions, you would begin with ammonia. When deliberations start in the coming days at the IMO, you will hear that A-word more than ever.

Delegates to the IMO’s Intersessional Working Group on Reduction of GHG Emissions from Ships will also talk a lot about LNG.

This may all happen on the sidelines of this important series of meetings in London, as the formal ­agenda is rather more technical.
