IMO MEPC 66 NOx Regulations and Arguments on SCR Technology

Last Friday on April 4, 2014, IMO MEPC on its 66th session, agreed on stricter requirements for vessels’ NOx emissions in specific areas, the so called NECAs. During this session the entry into force date of these requirements has been also agreed, although until the final MEPC decision, there was a disagreement for this matter from a number of countries headed by Russia.

Cutting NOx Emissions from Ships

A new ICCT study confirms feasibility of implementing new IMO standards for NOx emissions from ships on schedule in 2016. The study is a survey of technical literature and industry reports to assess equipment costs, environmental side effects, urea and catalyst availability and disposal, and overall system costs of SCR in the marine sector.
