Despite making the right environmental noises, the likes of Amazon, Tesla and Facebook came under fire earlier this year for failing to disclose their responses to climate change.

The failings of big tech emerged after global non-profit investors' organisation Carbon Disclosure Project (CDP) revealed in June that just 56% of the 1,320 companies it targeted this year had, at that point, responded to its request to disclose details of their activities.

But what of the nine “marine transportation” companies it has targeted this year?

Shipping has historically been graded average by the CDP, which requests information on the world’s largest companies' low-carbon policies on behalf of more than 590 institutional investor signatories.
