1.
Use of low-sulphur fuel
2.
Use of after-treatment such as scrubbers
Basically:
Guidelines for exhaust gas cleaning systems and wash water criteria are finalised as interim guidelines
Regulation 4: Equivalents
Emission reduction must be at least effective as using low S% fuel
Relevant guidelines should be taken into account
No impact on environments of other States
Using a SOx Scrubber is an acceptable Equivalent
How can new regulations for SOX and PM be met?

Low sulphur fuel
Use of low-sulphur crude oil, but limited availability
Blending of fuels is a possibility, and is done today
Desulphurisation of HFO
According to the major fuel companies :Much better investment to build high-efficient refineries that can produce more valuable products such as gasoline, diesel and LPG than to build desulphurisation plants for HFO.

Challenges of Low-sulphur HFO - Catfines
