Maritime Emission Control Areas

From 2011 to 2013
TML worked with the European Commission to investigate the effects of sulphur emission control areas and new NOx emission control areas on marine emissions, with the team updating emission inventories and developing scenarios for 2050. The analyses included cost-benefit assessments and emission scenarios for different sea regions, including the Baltic Sea, North Sea, and Mediterranean Sea.
The European Commission wanted to investigate the effects of sulphur emission control areas (SECAs) and new NOx emission control areas (NECAs) on emission limits for particulate matter, such as black carbon for marine sources. To gather quantitative inputs for such an assessment, a team with TML updated current information on ship emissions and developed scenarios for reducing ship emissions, especially in marine areas. Based on this, the team made an assessment in terms of costs and benefits.
TML's main role was to update the base year of the ship emissions inventory and develop emissions scenarios up to 2050. Scenarios include emissions of SO2, NOx, PM2.5, PM10, and BC.
TML was also involved in estimating the cost of emission reductions for each scenario.
The calculations covered the following sea regions within the EMEP grid: the Baltic Sea, the North Sea (including the English Channel), the North-East Atlantic, the Mediterranean Sea, and the Black Sea. In addition, these sea regions were divided into sub-regions depending on the distance from the coast. In the scenario analysis, regions that are candidates for new SECA and NEČAS were treated separately.
