Summary:
The IMO has set different
SOx limits over the years, including different limits for SECA and areas
outside SECA. The EU has formulated stricter limits for its member states. The
EU port and SECA areas have reduced SOx emissions vastly. Ocean acidification,
degradation of the environment, and human health has been improved in the EU
ports and SECA areas. However, the improvement at the global level is limited.
SOx emission causes a
cooling effect on temperature and decreases the warming effect of GHG emissions.
The lowering of SOx can impact global warming. Further, the Black Carbon
emission from alternate fuels can lead to increased GHG emissions. The acidic
wash water from EGCS contains toxic metals and PAHs which when discharged at
sea cause severe damage. The SOx reduction, Black Carbon emission and wash
water discharge adversely impact oceans and violates the UNCLOS, UNFCCC, Paris
Agreement, CBD, and even the UNDRIP. An IPCC report will help analyse the SOx,
Black Carbon emission, and wash water impact, which can be taken up in COP 28.
The 2022 MEPC Guidelines
for Environmental Risk Assessment and reception of wash water, with Port
authorities are based on the submissions by nations and environmental
organizations to the PPR 9, which have highlighted the environmental problems
and challenges in the use of EGCS and the discharge of its wash water. The
guidelines are non-binding and may not have the desired impact. Much stricter
regulation is required to ensure the protection of the marine environment.
