Increasingly strict emission standards apply to shipping around the coastlines of many developed countries. Presently these are mainly focussed on SOx, but in future, reflecting health concerns, increasingly strict limits are likely to address NOx and particulate matter. A variety of compliant solutions can meet present, and may be able to meet emerging and future standards. However, some of these solutions may lead to secondary impacts and new waste streams. The principal challenge is to better understand the comprehensive environmental impacts from the wide scale adoption of a range of potential emission reduction solutions together with any secondary effects on the on the marine environment.
To address these challenges, proposals should address all of the following aspects:
Assess the range of emission reduction technologies and designs which may be deployed, consider their cost benefits.
Experimentally characterise waste streams from emission control technologies, identifying the substances and quantities involved.
Considering several possible scenarios for the wide scale adoption of different emission control technologies depending on fuel costs, availabilities service needs etc model the disbursement of to the marine environment around the European coastline. Modelling should consider the main shipping routes, use real ship traffic, hydrological and weather data and the variety of constituents discharged. Consideration should be given to vulnerable regions such as estuaries and enclosed waters.
For the scenarios modelled assess the environmental impact on the marine environment in the medium and long term including consideration of any potential bio accumulation.
Considering SOx, NOx and particulate matter, assess and propose sustainable cost effective emission reduction strategies and technologies. Assessments should also include consideration of waste stream costs and their cost effective treatment.
