How to make emission regulations for NOx and SOx work
This paper discusses gaps related to emission regulations for ships with a focus on enforcement. Several gaps have been identified, some of them are regulatory gaps that typically include negative side effects of abatement technologies that could be addressed by policymakers. Other gaps relate to the enforcement of regulations. An important identified need is the development of onboard exhaust gas sensors that can be used in an enforcement context. These include NOX and ammonia sensors downstream an SCR, methane sensors for LNG engine exhaust and BC sensors for potential coming regulations on soot emissions from ships. Also methods and protocols for remote surveillance should be developed further. Enforcement regulations should ensure reliable performance over time, upstream and downstream of any abatement technologies.
