commissioned by the Canadian Government is recommending individual governments,
including Canada, to take unilateral action to restrict or prohibit scrubber
discharges from both open-loop and closed-loop systems.
Scrubber-fitted cruise ships cheat global fuel standard says the study
released by the International Council on Clean Transportation, claims that
ships, particularly cruise ships, fitted with scrubbers, were basically
‘cheating the global fuel standard’.
According to the
findings of the study, scrubbers, which are being used as an alternative to
low-sulphur fuels to comply with IMO 2020 Sulphur Cap, are harmful to both the
air and the sea.
Compliance with IMO does not guarantee that scrubber discharges are
exhaust gas cleaning systems, known as scrubbers, have been approved by the
International Maritime Organization (IMO). However, even though scrubber
discharges usually comply with IMO guidelines; the study indicates that
compliance does not guarantee that scrubber discharges are safe.
sulfur dioxide emissions, but when compared to low-sulphur fuels like MGO other
emissions were higher, specifically those of carbon dioxide, particulate
matter, and black carbon, the council said.
Scrubber discharged water more acidic and turbid than the surrounding
For water pollutants,
all scrubbers (open-loop, closed-loop,
and hybrid) discharge water that is more acidic and turbid than the surrounding
scrubbers emit nitrates, PAHs, and heavy metals, all of which can negatively
affect water quality and marine life.

Hence, the study
recommended the Canadian government to issue an immediate prohibition on using
scrubbers to comply with the Canadian portion of the North American ECA because
they are not equivalently effective at reducing air pollution as ECA-compliant
fuels. It also called for an immediate prohibition on all scrubber discharges
in Canadian ports, internal waters, and territorial seas saying that they

Resident killer whales and belugas already suffer from high levels of

IMO to prohibit use of scrubbers as a compliance option for new build
“We also recommend
that the IMO should consider prohibiting the use of scrubbers as a compliance
option for new build ships and work to phase out scrubbers installed on existing
ships…we found that using HFO with scrubbers is not equivalently effective at
reducing air pollution compared to using lower sulfur fuels, such as MGO,” the
Regulations have very little to do with science or ecosystem
“One thing this
federally-funded report makes abundantly clear is that the regulations have
very little to do with science or ecosystem protection,” said Anna Barford,
Canadian Shipping Campaigner, of Stand.earth environmental organization.

get ahead and bring in rules that protect people and vulnerable coastlines from
