Among the flurry of announcements at the COP26 climate conference was the formation of a body to set sustainability reporting standards for investors.

And buried in the hundreds of pages of industry-specific standards to be considered by the new International Sustainability Standards Board (ISSB) are a set of proposed rules for how shipping is expected to disclose its climate impacts to investors. (They are on page 562 of a supplement, to be exact.)

Amid the calls for shipping to take a more ambitious approach to decarbonisation, the industry-specific rules put forward are built on the existing disclosure requirements of the Sustainability Accounting Standards Board (SASB).
