Switching to compliant fuel overwhelmingly outweighs installing scrubbers when it comes to meeting the IMO's 2020 regulations, says a top investment bank.

A report by UBS found that only 2% of the global fleet would adopt scrubbers by 2020.

According to its survey of shipping executives, 68% of correspondents preferred adopting low-sulphur fuel to meet IMO’s cap on sulphur emissions, whereas only 21% chose installing scrubbers.
