Shipping's perception in the public mind as a "dirty" industry is probably speeding up its decarbonisation efforts, according to one executive trying to clean up the sector.

Martin Prokosch, head of Torvald Klaveness' decarbonisation company ZeroLab, said shipping's indirect Scope 3 emissions were really not on the radar for cargo owners a few years ago.

"But of the people we are talking to now, most are including shipping in their emissions scopes," he told the group's latest decarbonisation webinar.
