To talk about shipping and ESG — environmental, social and governance factors as they relate to business and finance — is to talk about the “E”.

More than the other two factors, environmental issues tend to be the focus when ESG comes up in shipping circles.

Because, unlike the “S” and the “G”, the “E” has incentives behind it as a worldwide emphasis on ­climate change has pushed regulations in the form of the Inter­national Maritime Organization’s carbon emission targets, giving the industry’s business partners a way to push change.
